- Learned that gases can be produced by a chemical reaction.
- Understood that mixing baking soda and vinegar can create carbon dioxide gas.
- Observed the process of the balloon inflating as it filled with the gas.
- Discovered that the gas takes up space and can expand the balloon.
- Realized that different amounts of baking soda and vinegar can produce varying degrees of inflation in the balloon.
For continued development related to this activity, encourage the child to:
- Conduct further experiments by altering the ratio of baking soda to vinegar and observing the resulting balloon inflation.
- Explore other materials or substances that can react with baking soda to produce gas, such as lemon juice or citric acid.
- Create a hypothesis about the effect of temperature on the reaction and test it by varying the temperature of the vinegar prior to mixing.
- Record their observations and findings in a science journal, including any changes they make to the experiment and their predictions for each variation.
- Discuss the importance of measuring precise amounts of baking soda and vinegar when conducting experiments, and practice using measuring tools like teaspoons or tablespoons.
- Research other chemical reactions that produce gas and conduct experiments to compare and contrast their outcomes.
