Objective

By the end of this lesson, you will understand the basic concepts of chemistry related to baking and be able to apply them in your own baking experiments.

Materials and Prep

• Measuring cups and spoons
• Mixing bowls
• Baking ingredients (flour, sugar, baking powder, etc.)
• Oven or stovetop
• Apron and oven mitts

Make sure you have adult supervision and permission to use the oven or stovetop.

Activities

1. Explore the properties of different baking ingredients:

   • Take small samples of flour, sugar, baking powder, and salt.
   • Observe and describe the color, texture, and smell of each ingredient.
   • Discuss how each ingredient contributes to the final product.

2. Mix and measure ingredients:

   • Follow a simple baking recipe, such as making chocolate chip cookies.
   • Measure and combine the ingredients in a mixing bowl.
   • Talk about how the ingredients interact and change when mixed together.

3. Bake and observe:

   • Preheat the oven to the required temperature.
   • Place the dough or batter in the oven and set the timer.
   • Observe the changes happening in the oven, such as rising and browning.

4. Taste and analyze:

   • Once the baked goods are ready, let them cool and taste them.
   • Discuss the texture, flavor, and appearance of the final product.
   • Reflect on how the baking process affected the ingredients.

Second Grade Talking Points

• "Chemistry is the branch of science that deals with the properties and interactions of substances."
• "Baking involves a chemical reaction called 'baking' or 'cooking' that transforms raw ingredients into delicious treats."
• "Different ingredients have different properties. For example, flour helps make things rise, sugar adds sweetness, and baking powder makes things fluffy."
• "When we mix ingredients together, they often change their appearance and texture. This is because of the chemical reactions happening between them."
• "Baking in the oven or on the stovetop uses heat to speed up the chemical reactions and turn the mixture into a finished product."
• "By tasting and analyzing our baked goods, we can learn more about how the ingredients and the baking process affect the final result."
