CURRICULUM SAMPLE

Chemical Reactions

Students will learn about chemical reactions by observing the interaction between baking soda and vinegar.

  • Baking soda (2 tbsp per group)
  • Vinegar (1/2 cup per group)
  • Dish soap (1 tsp per group)
  • Food coloring (optional, a few drops per group)
  • Small containers or bowls
  • Tray or plastic tablecloth (to contain spills)
  1. Introduction (5 mins):
    • Explain what a chemical reaction is (a process where substances change into new substances).
    • Discuss safety (wear goggles and ensure the workspace is protected from spills).
  2. Activity Setup (5 mins):
    • Give each group a small container.
    • Distribute the materials to each group.
  3. Experiment (15 mins):
    • Step 1: Add 2 tbsp of baking soda to the container.
    • Step 2: Mix in 1 tsp of dish soap and a few drops of food coloring.
    • Step 3: Slowly pour vinegar over the baking soda and observe the reaction.
    • Optional: Experiment with different amounts to see how the reaction changes.
  4. Wrap-Up (5 mins):
    • Discuss why bubbles formed (carbon dioxide gas released during the reaction).
    • Ask students to share their observations and reactions.
  • Understand that chemical reactions can produce gas.
  • Observe how substances transform during reactions.
  • Practice making hypotheses about changes.
  • Chemical reaction
  • Carbon dioxide
  • Reaction
  • Wear goggles to prevent splashes in the eyes.
  • Clean spills immediately to avoid slipping.
  • Do not taste or inhale any materials.

6 to 10 years old.
