Earth Day is an annual event celebrated on April 22nd to promote environmental awareness and sustainability. It’s a great time to teach kids about our planet and how we can all work together to protect it. In honor of Earth Day, here’s a fun and educational STEM activity you can do with your child: the baking soda and vinegar balloon experiment!
The baking soda and vinegar reaction is a classic science experiment that kids love. It’s simple, safe, and produces impressive results. Before you start, ask your child to predict what will happen to the balloon when the baking soda and vinegar combine.
You’ll need:
- A balloon (we drew the Earth on ours for Earth Day)
- 2 tablespoons of baking soda
- 1/2 cup of vinegar
- A funnel
- A bottle with a relatively small opening
Instructions:
- Put the baking soda in the balloon using the funnel.
- Pour the vinegar in the bottle.
- Stretch the “tail” of the balloon to completely cover the bottle opening.
- Lift the balloon and let the baking soda drop into the vinegar.
As the baking soda and vinegar react, carbon dioxide gas is produced. The gas expands and fills the balloon, causing it to inflate. As your child plays with the balloon, ask them about what is happening. What do they see and hear? What happens if they use more or less vinegar or baking soda? Why does the balloon fill up?
For safety, it’s important to remind your child not to inhale the gas directly from the balloon or bottle, as it can be harmful. Additionally, you should always supervise your child while they conduct this experiment.
Variations:
You can vary the experiment by using different amounts of baking soda and vinegar. Try using more baking soda or vinegar to see how it affects the reaction. You can also try using different types of balloons or bottles to see if it makes a difference. Encourage your child to come up with their own variations and see what they discover.
Additional resources:
If you’re looking for more Earth Day activities or STEM experiments, there are many resources available online. Check out websites like NASA’s Climate Kids, National Geographic Kids, or the EPA’s Environmental Education for Kids. You can also find many books and documentaries on environmental issues and sustainability for kids.
The baking soda and vinegar balloon experiment is a great way to teach your child about science and environmental awareness. By doing this simple experiment, you’re helping to instill a love and appreciation for our planet in the next generation. Happy Earth Day!
