Objective
By the end of this lesson, you will be able to understand the properties of various chemicals and their applications in everyday life.
Materials and Prep
- Lab coat and safety goggles
- Chemical samples (e.g., vinegar, baking soda, hydrogen peroxide, lemon juice)
- Test tubes and a test tube rack
- Measuring spoons and cups
Activities
-
Introduction to Chemicals:
Start by discussing the importance of chemicals in our daily lives. Give examples of chemicals commonly found in households and their uses. Encourage the student to share their own examples.
-
Chemical Reactions:
Perform simple chemical reactions using the provided chemical samples. Guide the student in measuring and mixing different combinations of chemicals in test tubes. Observe and discuss the reactions that occur.
