Objective

By the end of this lesson, you will be able to understand the basic chemistry concepts involved in baking a cake.

Materials and Prep

• Measuring cups and spoons
• Mixing bowl
• Whisk or spoon for mixing
• Baking pan
• Oven
• Ingredients for cake (flour, sugar, eggs, butter, baking powder, vanilla extract)
• Apron and oven mitts (for safety)

Before starting the lesson, make sure you have all the materials ready and read the recipe for the cake.

Activities

1. Measure the ingredients:

   • Using the measuring cups and spoons, measure the required amount of flour, sugar, baking powder, and butter as mentioned in the recipe.

2. Mix the ingredients:

   • In the mixing bowl, combine the measured ingredients and mix them using a whisk or spoon until they are well blended.

3. Add eggs and vanilla extract:

   • Crack the eggs into a separate bowl, check for any shell pieces, and then add them to the mixing bowl.
   • Add the required amount of vanilla extract to the mixing bowl.

4. Blend everything together:

   • Continuing to mix, blend all the ingredients together until you have a smooth batter.

5. Preheat the oven and bake the cake:

   • Preheat the oven to the temperature mentioned in the recipe.
   • Pour the cake batter into a greased baking pan and place it in the oven.
   • Bake the cake for the time specified in the recipe.

6. Cool, decorate, and enjoy:

   • Once the cake is baked, remove it from the oven and let it cool.
   • Once cooled, you can decorate the cake with frosting or any other desired toppings.
   • Finally, enjoy your delicious homemade cake!

Third Grade Talking Points

• "Chemistry is the branch of science that deals with the properties, composition, and behavior of matter."
• "In baking, we use different ingredients like flour, sugar, eggs, butter, baking powder, and vanilla extract."
• "When we mix these ingredients together, a chemical reaction occurs, resulting in the formation of a cake batter."
• "The oven provides the heat needed for the chemical reactions to take place, causing the cake batter to rise and solidify into a cake."
• "After baking, the cake cools down, and we can decorate it to make it look even more appealing."
• "Chemistry is all around us, even in activities like baking a cake!"
