Activities
1. Mix and Match: Mix different combinations of flour, sugar, and baking soda to observe how they react when combined with liquid ingredients.
2. Baking Powder Test: Mix baking powder with water to see the reaction and observe the formation of bubbles.
3. Baking a Treat: Follow a simple baking recipe and observe the changes in the ingredients as they are mixed and baked.
Seventh Grade Talking Points
- Chemical Reactions: "When we mix certain ingredients together, they undergo a chemical reaction, which means they change into something new."
- Baking Soda and Baking Powder: "Baking soda and baking powder are special ingredients that help our baked goods rise and become fluffy."
- Observing Changes: "As we mix and bake our ingredients, we can observe changes like bubbles forming and the dough rising, which are all part of the chemical reactions happening."
