The Garden Mural Project



This series of posts will cover many biology topics, especially for Preschool and Kindergarten aged students, although all elementary aged students will benefit from this study. This is a great study to begin in spring. The posts will cover nature study, hands-on projects and written science journal opportunities. The complete project takes about 16 weeks to complete.
1. Begin the Mural and Make A Field of Sunflowers: covers basic botany topics
2. Insects: Bees: includes parts of an insect and bee hive
3. Insects: Ants and Bees, begins the study of ants and their home, includes discussion of social insects and their behaviors
4. Insects: Butterflies and Metamorphosis: begins the study of butterflies and their life cycle, activities on butterfly behavior and how they protect themselves from predators. Also includes a comparison of moths and butterflies.
5. Helpful and Harmful Insects: Includes a study of ladybugs and aphids.
6. Spiders: Compares and contrasts the insect with the spider. Study of spiders and their homes.
7. Finishing Up the Mural: Study of what insects do in the winter, crickets and night insects. Sunflowers bloom and the meadow is complete.

Garden Mural Project, Lesson 7 Finishing up Insects and the Mural


Finishing up Insects and the Mural


Day 1: Learn what different insects do in cold weather (migrate, die, live dormant, hibernate, etc.)
Day 2: Read about other interesting insects such as Praying Mantises, Dragonflies, Damselflies, Crickets, Grasshoppers, Katydids and Cicadas and discuss what is learned. (Exploring Creation with Zoology I, by Jeannie Fulbright, chapter 13 is one such resource, or you may find books at the library.)

Day 3: On this week's nature walk, look for  Praying Mantises, Dragonflies, Damselflies, Crickets, Grasshoppers, Katydids and Cicadas (see the guidelines Handbook of Nature Study's Outdoor Hour Challenge, Dragonflies and Damselflies and Crickets, Grasshoppers and Katydids.) 

Day 4: If your student can find one, capture a cricket. Punch holes in the lid of a jar. Make a home for the cricket by picking plants and gather dirt from the area in which you find the cricket. Set a shallow container of water in the jar. Provide a variety in the cricket's diet with bits of lettuce, apple or oatmeal.  Have your student sketch the cricket in his nature  or science journal. 
Day 5: Have the student count the number of chirps in 15 seconds, add 40 and this is the approximate temperature. Do this several times to get an average. Discuss what an average is. Compare this with the temperature on a thermometer. Record all of this in the science journal. Do this as many times throughout the we as the student is interested. Release the cricket as soon as the activity is over.

Day 6: Take another insect nature walk, but this time at night. Compare what you find to what you found during the daytime.

Day 7: Your sunflowers' seeds have developed. Glue sunflower seeds to the paper flowers in your mural.

Garden Mural Project, Lesson 6: Spiders


Garden Mural Project, Lesson 6:  Spiders


Day 1: Teach the difference between an insect and a spider, by counting their legs (8, not 6) and body parts (2, not 3). Make a paper spider to add to your mural.

Day 2: For this week's nature walk, look for spiders and their webs. You may want to follow the guidelines at The Handbook of Nature Study's Outdoor Hour Challenge, Webs of All Kinds.

Day 3: Look at a variety of spider web designs. Place a sheet of waxed paper over the final web design. Secure the waxed paper to the background with tape. Using liquid glue on the waxed paper, have the student trace the web design. The glue should be in a continuous bead with not spaces. Let the glue dry overnight, Peel away the waxed paper, keeping the web of glue in one piece. Hang the web between two sticks or add it to your mural.
Day 4: Have your student select one type of spider to learn about and write a short report about it, including illustrations. (A good resource for this is chapter 13 of Exploring Creation with Zoology III, by Jeannie Fulbright or you can find resources at your library.)
Day 5: A Ground Spider uses a depression in the ground and, covering the hole with leaves and twigs, traps an unsuspecting insect as it falls through. You may make one of these, using a brad to make a door that can swing back and forth.

Day 6: Learn about other arthropods such as scorpions, centipedes, or isopods.  (A good resource for this is chapter 2 of Exploring Creation with Zoology III, by Jeannie Fulbright or you can find resources at your library.) What is an arthropod?

Garden Mural Project, Lesson 5: Insects/Helpful and Harmful Insects



Insects/Helpful and Harmful Insects


Day One: Learn about the damage that insects can do.  Loosen some of the tape that held the flowers on the mural, to make them "wilt" to represent the damage that aphids can do.

Day Two: Learn about helpful insects. Make paper ladybugs to eat the aphids. Fold a round shaped piece of paper in half and put dots of black paint on one half. Fold over again and the identical spots will appear on the other side. Discuss symmetry.

Day Three: On this week's nature walk, look for ladybugs and aphids (you may want to use the guidelines from the Handbook of Nature Study blog's Outdoor Hour Challenge #26.)

Day 4: Discuss and have your student make one list telling how insects are helpful and another telling how they are harmful.

Day 5: Read about beetles, flies and true bugs and discuss what is learned. (Exploring Creation with Zoology I, by Jeannie Fulbright, chapter 12 is one such resource, or you may find books at the library.) 

Day 6: On the next nature walk, take along a picnic to enjoy (see the guidelines Handbook of Nature Study's Outdoor Hour Challenge #10:Picnic.)  Discuss about which insects they see are harmful to the picnic. See if your student can find a beetle, fly or true bug on the nature walk.

Garden Mural Project, Lesson 4: Insects: Butterflies and Metamorphosis



Lesson 4: Insects: Butterflies and Metamorphosis

Note: On day 12 there is an option to obtain a butterfly raising kit or bring home caterpillars to raise to adulthood. You will want to do this in advance and you can begin day 12's activities whenever you receive the kit.


Day 1: Explain that every insect begins life as an egg. The growth time from egg to adult may vary from a few days to 17 years! Most insects follow one of three patterns of growth and development: simple growth and development, incomplete metamorphosis and complete metamorphosis. Have resources for your student about insect life cycles. (Exploring Creation with Zoology I, by Jeannie Fulbright, chapter 10 is one such resource, or you may find books at the library.) Simple Growth and Development: Show pictures of a Silverfish and Springtail in the field guide. These are wingless insects and they grow and develop in three stages: 1. an adult lays an egg, 2. it hatches and looks like a small adult, 3, it's looks don't change as it grows and molts and it reaches adulthood with almost no change. Look for these insects in your nature walks.
Day 2: Incomplete Metamorphosis: Look up grasshoppers, mayflies, roaches, damselflies, dragonflies or cicadas. They go through an incomplete metamorphosis: 1. An adult lays an egg, 2. A nymph that hatches from the egg looks much like the adult but wingless, 3. The adult comes of to the last most with wings. Look for these insects in their various stages on your nature walks.
Day 3: Look at pictures of butterflies, moths, beetles, flies, bees, wasps or ants. These insects grown and develop in a complete metamorphosis: 1. An adult insect lays an egg, 2. A larva hatches that looks completely different from the adult, 3. After the larva is grown, it turns into a pupa. 4. The winged adult emerges from the pupa. It appears completely different from earlier stages. Make butterflies from construction paper.

Day 4: Find resources, read about the Order Lepidoptera and discuss what is learned. (Exploring Creation with Zoology I, by Jeannie Fulbright, chapter 14 is one such resource, or you may find books at the library.)


Day 5: On this week's nature walk, look for moths and butterflies. Begin making your own Insect Field Guide, like the DIY Bird Field guide at the Handbook of Nature Study's Outdoor Hour Challenge #7.


Day 6: Have your students glue eggs (navy beans) to leaves of the paper flower he has made to represent the adult butterfly laying eggs on the leaves.

Day 7: The larva of butterflies are called caterpillars (larvae of flies are called maggots, larvae of beetles are called grubs, larvae of mosquitoes are called wigglers, etc.) Make caterpillars from construction paper. 

Day 8: The pupa of a butterfly is called a chrysalis. Make an oval pocket to represent the chrysalis by folding a piece of tan construction paper in half and cutting it into an oval shape and then sealing it, leaving an opening so that you can slip the butterflies the students have made into the chrysalis. Have your student sponge paint to add texture. 

Day 9: 
While your student isn't looking, slip their butterflies into the chrysalis pockets and tape them shut. Let your student help the butterflies emerge from their chrysalis.
    Butterfly Metamorphosis
Day 10: On a paper plate or piece of paper, have your student draw the arrows of the butterfly's life cycle, leaving a space for the four states between the arrows. Have your student glue dried beans to the plate for the eggs, spiral pasta for the larva, shell pasta for the pupa and bow tie pasta for the adult butterfly. Add leaves, a branch and paint to finish.

Day 11: On this week's nature walk, bring along a magnifying glass to look at the insects. You may want to follow the guidelines outlined at the Handbook of Nature Study's Outdoor Hour Challenge #8, Up Close and Personal.


Day 12: (Optional) Obtain a butterfly raising kit or bring home caterpillars to raise to adulthood. Make sure you know and have access to a supply of the caterpillar's chosen food. If you decide to do this, have your student keep note of observations in his science journal. Entries should be kept most days, noting changes that occur as the larva changes into the chrysalis and then into an adult butterfly. Tell him to draw pictures and record color, shape, size, texture and position of each stage. Encourage him to ask questions.

Day 13: Hungry butterflies go right to the flowers to gather nectar. Have your students drink nectar (juice) with probiscus (straws.)

Day 14: Learn how butterflies avoid predators. We learned that many butterflies have large circles of color on their wings called "eye spots." They are called that because they look like eyes of a large creature, like an owl, to a bird who might otherwise be a predator to the butterfly. This scares the birds away. Have your student add colored circles to his paper butterfly.

Day 15: Compare butterflies and moths. Make a Venn diagram in his science journal. (Butterflies fly during the day, have knobs at the end of their antennae, have thin, hairless bodies, rest with their wings held upright, etc. Moths fly at night, their antennae are not knobbed, have, plump, furry bodies and rest with their wings spread, etc.)

Day 16: For this week's nature walk, have your student rope off a small square of his backyard to observe what insects can be found in that area. You can use the guidelines Handbook of Nature Study's Outdoor Hour Challenge #9, One Small Square.

Garden Mural Project, Lesson 3: Insects: Ants and Bees


Garden Mural Project, Lesson 3: Insects: Ants and Bees

This lesson is designed to last three weeks or more.


You will need to purchase an ant colony kit in advance or have available the materials to make an ant colony in a glass jar. (Instructions on how to make an ant colony with jars can be found here.)


Day One: Ants and Bees are both social insects. Research and discuss social insects. (Exploring Creation with Zoology I, by Jeannie Fulbright, chapter 11 is one such resource, or you may find books at the library.) Make ants to add to your garden out of black construction paper. Use 3 ovals, a small, medium and a large one, and 8 thin rectangles. Guide your student to glue the three ovals, with the smallest at the top and the largest on the bottom. Review body parts. Have them glue the legs and antennae on in the appropriate places. Review how many legs insects have and the word antennae.

Day 2: Have your student look through books on ants and then write about one species of ant or draw and describe an ant colony in his science journal. 
"Children should be encouraged to watch, and quietly, until they learn something of the habits and history of the...ant..." -Charlotte Mason, Home Education, Vol. 1. p 57
Day 3: Set up the ant colony kit or make one in a glass jar. Have the student fill a large glass jar full of dirt and tape dark construction paper around it. Wait until tomorrow to add the ants. (Full instructions can be found here.)
Day 4: For this week's nature walk, focus on finding and observing ants. You can follow the guidelines at the Handbook of Nature Study blogOutdoor Hour Challenge, Ant Study. Look for an ant hill, and observe the ants coming and going on the hill. Discuss what they are doing. Carefully dig up the ant hill, including the surrounding dirt and place it all in the jar you have prepared. Place wet piece of cotton on the dirt and keep it damp to provide moisture for the ants. The ants may be fed by adding ant food or tiny table scraps twice weekly. Make holes in the lid and secure. To observe the ants, remove the dark paper. Have the student draw a picture of what he sees.
Day 5: Most insects have two antennae. The antennae are used to feel and smell and sometimes taste and hear. Ants and bees rely more on their sense of smell than their sight to tell who belongs in their colony. Give everybody in the family (or group of friends) cups with cotton balls - half scented with strawberry extract and half with vanilla extract. The strawberry scent represented the ants and the vanilla represented the bees. Have one student play the role of the sentry bee of the bee hive was responsible for letting in the bees (vanilla scented cotton balls) and stinging the ants (strawberry scented cotton balls). 
Day 6: Have your student make paper tunnels and chambers and have your student add this to the mural.
Day 7: Using the mural and the paper ants, act out stories of insect behavior. The hungry ants go searching for food and sometimes invade a beehive because they smell the sweet honey. They try to get in to get the honey but the hive's sentry bees won't let them. 
source
Day 8: The foraging ants can discover aphids on the flowers. Make paper aphids to put on the paper plants. These look similar to the ants, but are made from light green paper. Ants love to get honeydew that the aphids excrete from their bodies, and the aphids like the protection the ants can give. This is a symbiotic relationship.
Day 9: When a scout bee finds a good source of nectar, it dances a special figure 8 dance. The more rapid the dance, the nearer the food. The angle of the dance indicates the relationship of the nectar to the sun. Have the student pretend to be a bee that has just found a garden full of flowers containing nectar. Place a picture of a flower somewhere in the room and have the student do a dance of body language to show another student or family member where they can find the flower. Make sure the student knows he cannot point or look at the flower picture. 
Ants also forage. If you have a large enough group, you can have the ants forage and bring back food to their nests, too.
Day 10: Once bees are old enough, they follow the forager bees' instructions to find flowers and gather nectar and pollen. After having your paper bees visit the paper flowers on the mural, add pollen bags (of construction paper) on the back legs of our bees and glue pollen (cornmeal) to them, simulating the pollen they would have picked up from visiting the flowers. Give your students Cheetos for a snack and show them how they get the orange color from the Cheetos on their fingers just as the bees get the pollen on their legs.
Day 11: On this week's nature walk, have the student begin a list in his science journal of all the insects he finds and identifies. He may add to this list each week. (See Handbook of Nature Study blog's Outdoor Hour Challenge #5.)

Day 12: Give your student the seven hexagons that you made in lesson 2. Have him write a fact about bees on each hexagon and then glue the hexagons together in his science journal to make a honeycomb.

Garden Mural Project, Lesson 2: Insects, Bees


This lesson should last for two weeks.

Day 1: What insects live in a particular location?
Make a can trap to capture the insects of a particular location, such as a part of your backyard. 
Punch holes in the bottom of an empty, clean can. This will make sure that the can does not fill up with water if it rains. Dig a can-sized hole in the location of your choice and place the can in the hole so that its top is at ground level. Put some food for the insects in the can, such as fruit or meat. Cover the top of the can with a board, and put rocks around the edges of the board to life it a few inches from the ground. Check the can regularly and identify the insects that come to your can. Have your student count the number of each type of insect and record all of this in his science journal.
Day 2: Learn about the parts of an insect. 
Lead the student to identify the three body segments common to all insects: head, thorax and abdomen. Discuss how most adult insects have wings. 
Have your student make some aphids out of construction paper and put them on the leaves of the flowers he has made. 
Study the different mouthparts of insects by looking at pictures of insects in books.

Day 3: Insect Symmetry
Have your student make a paper adult butterfly. Fold a piece of construction paper in half. Open the paper and lay it flat on the table. Cut out a butterfly shape. Have student paint details of the butterfly on one side and fold the paper over again. When the butterfly is completed, both sides of the butterfly are exactly the same. They are symmetrical, mirror images of each other. Discuss the concept of symmetry.
Day 4: Nature Study
For this week's nature walk, encourage your child to look for insects. Take an insect field guide with you on a nature walk. Help the student look for and identify insects that you find. What physical characteristics do all insects have in common? Have the student draw a picture of the insect with every feature that makes an insect and insect. Allow the student to refer to the field guide to make an accurate drawing of the insect. Encourage the student to add the natural environment in which the insect was observed. Write any of the student's comments on the page. 

Day 5: Compound Eyes and Nature Walk
Many adult insects have compound eyes. Compound eyes are made up of thousands of tiny separate lenses that work together to complete a picture. Notice the eyes in the insects you find and record on your nature walks.

Day 6: Exoskeletons
All insects have a tough, shell-like outer covering called an exoskeleton. As an insect grows, it sheds or molts one hard shell that is replaced by another. Point this out for observation on your next nature walk.

Day 7: The Beehive
Cut out seven circles, nine squares and seven hexagonal shapes out of yellow construction paper. Allow the student to explore which cell shape is the most efficient building block for a beehive. The cells should fit together without wasted space. Lead the student to the conclusion that the hexagon's six-sided shapes are best because they fit the bee's body shape and fit snugly together. Save these hexagons for a later project.


Day 8: Adding a Bee Hive to the Garden Mural
Have your student make a bee hive out of a paper bag for our mural. Cut a hole in the paper bag for the hive entrance. Glue egg cartons inside the bag for the honeycomb.

Day 9: Bee Stings and a Nature Walk
Talk about bee stings and what is the best behavior for a person near a bee. 
For your next nature walk, focus on your student drawing a sketch in his science journal of a bee or other insect in his science journal. If your student is having difficulty with this, you can follow along with the Outdoor Hour's Getting Started Challenges found at the Handbook of Nature Study blog. Challenge #3 helps guide the student to draw in his journal and #27 focuses on Bees.

Day 10: Paper Bees and Honeycomb
Make bees out of paper and add a Queen Bee and Worker Bees to the hive. Review the parts of insects and compare them to the aphids. Discuss how newly hatched bees work inside the hive first, keeping the hive warm, making wax and feeding the larvae. 
Look at real honeycomb from a jar and taste the honey.

Garden Mural Project, part 1: A Field of Sunflowers



This project is a great spring activity to do with preschool, kindergarten or mixed age groups. Students of all elementary grades can benefit from this study. You only need to raise your expectations on how much they can learn and remember and how well they can express what they have learned. They can write their own narrations, for example.
This portion should take a preschool or kindergarten student two weeks to complete.



Mural: Obtain a very large piece of paper or tape several pieces together in order to get a wall-sized mural. Have your student paint the background brown on the lower half for the ground level and blue on the upper half for sky. 

Nature Walk: Weather permitting, take a nature walk with your student each day. It is beneficial for you to read the first part of Anna Comstock's Handbook of Nature Study, The Teaching of Nature-Study, if you have no experience in nature study and its goals. For your first nature walk, have your student just spend time outside and allow him to play in the dirt and point out the blue sky to him. Once inside, have him sketch his experience outside with the earth and sky. For all his nature journal entries, he may choose to just sketch or he may want to include some observations with the sketches. If he is able to write these observations himself, he may, but this is also a good opportunity to have him narrate verbally while you write these down for him on the page.

“...the teacher should have in mind clearly the names of the parts which she wishes to teach...When talking with the pupils about flowers let her use these names naturally...-Handbook of Nature Study, page 456

A Field of Flowers: Learn about the parts of flowers while making the blossoms from paper plates and stems, leaves and other parts from colored construction paper. 
Prepare for this project by gathering together plain white paper plates, tan and green construction paper and sunflower orange-yellow paint. Your student will paint the paper plate with the yellow paint. Then he can glue a tan circle made from construction paper in the center of the plate and glue strips of green construction paper to form the stem. Lastly, he can glue green leaves onto the stems. You must determine in advance whether you need to cut these parts out for him in advance or whether he should cut them out himself. It all depends of the development of the child and what you are working on with him. It is no less his project if you have to cut the parts out for him and he glues them together.
As you are working with the student, making the flower, casually use the correct terms for the parts of the flower. (See Anna Comstock's Handbook of Nature Study, pages 456-457 for details on how to do this.)


Seed Germination: In advance, purchase some sunflower and some bean seeds. You will also need a plastic cup, some potting soil, a glass jar, paper towels and water.

Have them observe the seeds, perhaps with a magnifying glass. Have him compare and contrast the seeds and sketch his observations in his nature journal, including his narrations, if desired.


Next. have him push sheets of paper towel, one at at time, into the glass jar. Once full, add water to wet the paper towels, making sure to dump out the excess water. This will allow more room for additional paper towels, which you can pack in the middle to soak up any excess water and will make sure that the seeds will stay in place.  Now have your student place the seeds in the jar between the wet towels and the glass of the jar. Have him draw this in his science journal. He can view the development of the seed and journal this during the weeks to come.



Have your student plant sunflower seeds in plastic cups of soil. Have your student observe and sketch the plant's development regularly in his science journal. Be sure to include the dates. 
Nature Walk: During this week's nature walk, look for some garden flowers in your own yard or neighborhood. You only need to spend 15-20 minutes on this nature walk. Compare and contrast the flowers that you see. Begin to use the correct labels for plant parts that you have learned. Give your student an opportunity to make a journal entry after each nature walk.

    Hands-On Middle School and High School Biology

    Here is the newest biology curriculum that I have put together. We will be doing some of the activities throughout the summer and on into the fall. This program is designed for students from Middle School level to High School grades. You will, therefore need to establish for yourself the level which meets the standard for your student(s) grade level(s). Everything should reflect the students' mastery of the material covered. Students will need a blank notebook to record information. I ask my students to keep wide margins on the left side of their notebook pages and double space their writing so that they can go back and add questions, comments and reflections in the margins.

    Part 1: Introduction to Biology


    from the experiment Osmosis and Diffusion...what is the difference?


    The Chemistry of Life

    Students review molecular biology concepts. They also observe and learn about the processes of diffusion and osmosis. Students learn the basics of organic chemistry and see how easily enzyme function can be destroyed.

    The Cell

    Students further their knowledge of internal structures of various cells by viewing cork and onion epidermis cells. Slides of cells are viewed microscopically and students are challenged to determine whether they are viewing plant or animal cells. Students observe cytoplasmic streaming and the response of plant cells by the presence of salt. Banana cells are also viewed to see what the largest part of the cells contain.

    Cellular Reproduction

    To observe the physical characteristics of DNA, students extract DNA from strawberries or onions. Students observe under the microscope how a cell divides during mitosis and observe the difference between plant and animal cell division. Students also construct a model of a virus and learn about its characteristics. 

    Genetics

    Students learn about the history of genetic research and how to make Punnet Squares. Students learn about a Di-hybrid cross to understand how multiple traits are passed from one generation to another. Students will also understand how sex - linked traits are passed from parents to offspring. 

    Evolution

    Students will learn about Charles Darwin and his theory. 


    Part 2: Aquatic Habitats


    Pond Life

    Study ecosystem of a pond and collect and culture specimens from a pond. We will collect four jars of pond water and culture them with hay, rice, egg yolk and soil, separately. 

    Microscopic Pond Life, part 1

    Identify and sketch organisms from the collected and cultured specimens using a microscope. 

    Microscopic Pond Life, part 2

    Look at the same cultures a week later. Do the organisms differ from the week prior?

    Constructing a Pond Model

    Using gravel, sand, water plants such as Elodea and 1 1/2 gallon aquarium, students create a pond model. They record what they have done in science journals and predict changes the habitat may go through in the future. Students also look at the  Elodea under the microscope.


    Kingdom Plantae

    Students learn about basic plant anatomy, macroscopic and microscopic structures of a leaf, Students begin leaf identification and a leaf collection. Students learn how anthocyanin and pH help determine leaf color. Students learn about plant stems and roots and look at examples of them (both monocot and dicot) under a microscope. Students learn the basics of plant classification. 

    Adding Tubifex Worms and Snails to the Pond Model

    Students add Tubifex worms or Daphnia and Snails to the pond model, one at a time and record observations. Students also observe Tubifex worms under the microscope to learn about their body structure.

    Adding Fish to the Pond Model

    After observing and recording the structures of fish, the Gambusia, Guppies or Goldfish are added to the model pond and then their behavior is observed and recorded. Predictions are also recorded. Fish scales are viewed under the microscope. 

    Mosquitoes

    As the pond model habitats begin to resemble an actual pond, interactions are observed and recorded. Decomposition may be covered. Mosquito larvae are observed and then added to the habitat. 

    Designing and Conducting Experiments

    Students will be asked to come up with their own question to investigate by designing and conducting their own experiment using the scientific method, which will be accurately recorded.


    Subkingdom Algae

    Students will observe microscopically and microscopically at least two of the five phyla of the Subkingdom Algae. 

    The Pond Models will be kept and observations recorded while we go on to further studies.

    Part 3: Forest Habitats


    Exploring Soil

    Soil will be collected from different places and compared. The samples will be viewed under the microscope. Soil profiles will be done on each of them. 

    Building the Forest Model

    Using a plastic container, sand, birdseed or grass seed, dry leaves, twigs and a strawberry,  alyssum, Violet or other small garden plant, students will create their own Forest models. They will record what they have done in their science journals.


    Inside a Flower
    source

    Plant Physiology and Reproduction

    Students learn how plants use water, including viewing xylem under the microscope. Students learn about plant growth and reproduction, including dissecting and labeling plant parts. Students observe various types of fruits and classify them based on their differences. 

    The Environmental Factor and  it's Effect on Radish Leaf Color

    Students will observe the effect that the environment has on a genotype to make its phenotype change.

    Ecosystems

    Carbon Dioxide and the Greenhouse Effect 

    Using a thermometer and a plastic 2-liter bottle, students will observe the ability of carbon dioxide to absorb energy from sunlight. These findings will be recorded in their science journals. The water cycle, the oxygen cycle and the carbon cycle are covered.

    Adding Earthworms to the Forest Model

    Earthworms are observed and recorded about before being added to the habitat. Their role as decomposes are discussed. 

    More About Earthworms

    Invertebrates as a class are studied. Earthworm anatomy, including internal structures, are recorded. Experiments are designed and conducted using g earthworms as the basis of the study.

    Adding Isopods to the Habitat

    Students will be encouraged to identify and understand Isopod structures and behavior while adding them to the Forest Model. 

    Adding More to the Forest Model

    Students can add one additional thing they collect to their Forest Model, such as Garden snails or slug, beetles, crickets and the like. They could instead add an inanimate object such as rocks, shells, and the like. Observations of any interactions are recorded. Just as the Pond Models were kept and ongoing observations were recorded, the Forest Models are also kept, observed and recorded. This will overlap with the activities in part 3, so that the activities in part three are conducted with both a cricket and the mammal.
    from Kingdom Fungi

    Kingdom Fungi

    Students observe fungi and learn how members of the class Basidiomycetes grow and reproduce. Can they grown in the Forest Model? Students also learn about the fungi of the Class Ascomycetes, in comparison and contrast to Class Basidiomycetes. Students observe how yeast reproduce through budding. This is compared to how Class Zygimycetes grow and bud. Various molds and mildew, as well as Impertfect Fungi, will be observed microscopically and microscopically.  

    Part 4: Mammal and Insect Observations


    The Animal Corral

    Students learn the basics of scientifically observing animal behavior as they read about scientists such as Jane Goodall and begin observing animals is a animal corral. They learn about how assumptions and anthropomorphism affect our ability to accurately observe animal behavior.

    Stimulus and Response

    Students introduce stimulus objects, such as foods, into the animal's environment and observe how the animal reacts. Students generate hypotheses about how certain behaviors help animals in the wild survive. Students discuss the shortcomings of observing animal behaviors. 

    The Sampling System

    As a continuance of the last section's discussion, students discuss the value of mapping animal movements. They then learn to use a time sampling system of mapping animal movements. 

    Holding and Observing Animals

    Humane treatment of animals is covered and students practice how to humanely handle both a cricket and a rat. They also observe and record the physiology of the  cricket. Using drawings, the internal structures of the cricket are also explored and compared to the internal structures of the mammal. Insect identification is also learned. 

    Designing Experiments

    Students design their own animal behavior experiment by choosing a single stimuli and a topic to investigate. The topic is then narrowed to one hypothesis that can be tested within a half-hour period. The choices available to the animal are identified as well as the actions that will be observed and recorded. The concept of a fair test will be covered.

    Mapping Animal Movements

    Students use a sampling system to map the movements of a rat and a cricket. First they are observed and mapped as they explore an empty container and then after food and a shelter are added.

    Identifying Movement Patterns

    Students construct bar graphs as a first step in analyzing the mapping data they have collected. They then compare the trials conducted with and without stimulus, and the differences in behavior revealed by the data for the rat and the cricket. How does the behavior of the cricket and the rat differ from each other? The concept of key location is also covered. Students can also take this technique into the field by conducting a similar experiment in the backyard or a park.


    Experiments

    Students get the materials they need and set up their experiments. After the experiment has concluded, students record their results and write their conclusions.  

    Scientific Convention

    With an audience, students describe their experiments and summarize their results. At the end of each report, there is a period of comments and questions from the audience. Students may wish to revise and improve their experiments.


    Part 5: Other Areas of the Animal Kingdom


    from Phylum Cnidaria

    Other Invertebrates

    Students observe a specimen from the phylum Porifera and note the simplicity, yet complexity of this animal's support structure. Students also observe the hydra and a planarian.


    Class Aves (Birds)

    Students observe bird embryology, look at feathers under a microscope,  learn types of feathers and skeletal structures. Student begin bird identification in the backyard and through field trips to nature centers, parks and bird sanctuaries.
