Objective
By the end of this lesson, the student will understand the science behind baking cookies, including the role of ingredients, the process of baking, and how different factors can affect the outcome of their cookies. They will also gain hands-on experience by making their own batch of cookies.
Materials and Prep
- All-purpose flour
- Granulated sugar
- Brown sugar
- Unsalted butter
- Eggs
- Baking soda
- Vanilla extract
- Salt
- Chocolate chips (or other mix-ins)
- Mixing bowl
- Measuring cups and spoons
- Baking sheet
- Parchment paper (optional)
- Oven
Before starting the lesson, ensure that the oven is preheated to 350°F (175°C) and that all ingredients are measured out and ready to use.
Activities
-
Ingredient Exploration: Discuss each ingredient and its function in the cookie-making process. For example, explain how flour provides structure, sugar adds sweetness, and eggs bind the ingredients together.
-
Cookie Mixing: Guide the student through the process of mixing the ingredients together. Encourage them to observe the changes in texture and consistency as they combine the ingredients.
-
Shape and Bake: Allow the student to shape the cookie dough into balls and place them on the baking sheet. Discuss the importance of spacing them out for even baking.
-
Observe and Taste: While the cookies are baking, encourage the student to observe changes in color and texture. Once baked, enjoy tasting the cookies together and discuss the results.
Talking Points
- "Flour is the backbone of our cookies; it gives them structure and helps them rise."
- "Sugar not only sweetens our cookies but also helps them to brown and become crispy on the edges."
- "Butter adds flavor and moisture; it makes our cookies rich and delicious."
- "Baking soda is a leavening agent; it helps our cookies rise and become fluffy."
- "Eggs play a crucial role in binding the ingredients together, making our cookies hold their shape."
- "The temperature of the oven is important; it affects how quickly our cookies bake and their final texture."
- "Different baking times can result in different cookie textures; a shorter bake time gives chewy cookies, while a longer bake time gives crispy cookies."
