St. Patrick's Science: Seeing Rainbows

Learning About Lenses

Rainbow Density
Make a rainbow with different densities of sugar water.

Using six heat-safe containers, add 1 tablespoon of sugar to the first cup and add an increasing amount of sugar to each cup, adding an additional tablespoon each time. 
Add food coloring to each cup, according to the colors of the rainbow.
Dissolve the sugar and food coloring  in one cup of boiling water for each container.
Here is the secret to success-
move from least dense to most dense, releasing each new layer on the bottom of a test tube, with the straw, instead of trying to pour it onto the top.

Rainbow Milk



Begin with a bowl of milk. Drops of food coloring are added.
Soap is added.
As the soap breaks down the fats in the milk, it moves in currents, which move and mix the colors.


Rainbow Pizza


This isn't a science experiment, but it is a nice reward and it is its own rainbow.

Crust
Press sugar cookie dough into a pan, I used a tart pan, and bake according to cookie recipe. Allow to cool completely.

Filling
8 oz softened cream cheese
2 tablespoons powdered sugar
4-6 oz Cool Whip

Put all ingredients into a bowl and beat until smooth and creamy. Spread over center of sugar cookie crust. Cover and refrigerate until ready to top and serve.

Topping
Sliced fruit of your choice. I used strawberries, clementine sections, sliced bananas tossed with a little lemon juice, kiwi, and blueberries. Make sure all fruit is patted dry to keep the juices from making the crust soggy.

  2. Oops, clicked too fast or something, but blogger got mad.

    I love the collection of rainbow ideas you had. I'm waiting to try some of these until the kids are a little older.

  5. Now, if only I had all that fruit for the pizza, I'd make it first thing in the morning. Love all of this.
