The next "secret formula" we made was for ice cream.

Fifth Student eating green ice cream from a bag?Let me explain how we made ice cream, the "secret formula" way.
First they had to decide how much of each ingredient they wanted to add.
The ingredients were sugar, choice of either strawberry or vanilla flavorings and choice of any combination of red, blue or yellow food colors.
They added these to 3 ounces of cream in a baggie.

They added these to 3 ounces of cream in a baggie.
The baggie was put in a cup so they had both hands free to measure.
After some of each ingredient was added, they tasted them to see if they were "just right."Now the fun began. The small individual bags were put into a large (gallon) baggie. Rock salt and ice were also added to the baggie. Ice cream will not freeze unless the temperature gets below 27 degrees, so the salt is added because it lowers the freezing point of the ice.
The baggie was then put inside an old T-shirt. The boys took turns shaking the ends of the T-shirt to keep the ice cream churning.
Is it done yet?
Now they get to try their own ice cream.
They seemed to enjoy their own creations and eating ice cream from a bag.

GEMS Guide Secret Formulas Grades 1–3
Students eagerly investigate the properties of substances as they make their own personal brands of paste, toothpaste, cola, and ice cream. The activities have been designed to convey key science/mathematics skills and concepts, provide motivating real-life experiences with chemistry, and build comprehension of cause and effect, central to later understanding of controlled experimentation. Secret Formulas speaks to the need expressed by many primary school teachers for more high-quality physical science activities.
