Step-by-Step Procedure

  1. 1

    Use the funnel to add 3 tablespoons of baking soda into the balloon.

  2. 2

    Pour 1 cup of vinegar into the plastic bottle.

  3. 3

    Carefully stretch the balloon opening over the bottle's mouth without spilling the baking soda.

  4. 4

    Lift the balloon to let the baking soda fall into the vinegar.

  5. 5

    Observe the reaction as gas builds up and inflates the balloon.

  6. 6

    Record the observations and measure how much the balloon inflates.

  7. 7

    Experiment with different amounts of baking soda or vinegar.

  8. 8

    Discuss the chemical reaction involved.

  9. 9

    Present the results and demonstrate the experiment.

  10. 10

    Conclude with the scientific principles behind the reaction.

Expected Results

The balloon should inflate as the reaction between baking soda and vinegar releases carbon dioxide gas. This demonstrates how chemical reactions produce gases.

Variables

Independent Variable

Amount of baking soda or vinegar used

Dependent Variable

Size of balloon inflation

Controlled Variables

Type of balloon, Temperature of the reaction, Container size

Safety Notes

Wear safety goggles during the experiment. Avoid contact with eyes and skin from the vinegar.

Presentation Tips

  • Show the inflation process live during the presentation.

  • Explain the chemical reaction in simple terms.

  • Engage the audience with questions about gas production.

  • Use visuals to illustrate the reaction process.

  • Practice your presentation to ensure clarity.

Frequently Asked Questions

What gas is produced in this reaction?
