Objective
By the end of this lesson, you will understand the basic principles of chemistry and how they relate to cooking.
Materials and Prep
- Measuring cups and spoons
- Mixing bowls
- Various ingredients used in cooking (e.g., flour, sugar, salt, baking powder)
- Stove or hot plate
- Pan or pot
- Apron and oven mitts (for safety)
- Access to a kitchen
- Prior knowledge of basic cooking techniques
Activities
-
Activity 1: Introduction to Chemical Reactions
Discuss with the student how cooking involves chemical reactions. Explain that when ingredients are mixed together and subjected to heat, new substances are formed.
Example: When baking a cake, the batter undergoes a chemical reaction in the oven, resulting in a fluffy and delicious cake.
-
Activity 2: Measurement and Proportions
Have the student measure and mix different ingredients in various proportions to understand how changing the amounts affects the final outcome.
Example: Prepare three batches of pancakes with different amounts of baking powder. Observe how the thickness and fluffiness of the pancakes vary.
-
Activity 3: Heat and Cooking
Guide the student through cooking a simple dish, such as scrambled eggs or pancakes, while explaining the role of heat in cooking.
Example: Demonstrate how eggs transform from liquid to solid when heated, and how different cooking times and temperatures can affect the texture and taste.
Seventh Grade Talking Points
- "Chemical reactions occur when substances combine and create new substances with different properties."
- "In cooking, ingredients undergo chemical reactions when mixed together and exposed to heat."
- "Measuring ingredients accurately is important to maintain the right proportions for desired outcomes."
- "Heat is a form of energy that causes molecules in food to move faster, leading to changes in texture, taste, and appearance."
- "Understanding the science behind cooking can help us become better cooks and experiment with new recipes."
