Billowing Balloon Fun!

Yesterday we did another really exciting Change experiment with Mrs Esquilant. We wrote up a procedure to show our experimental process.

Goal: We want to investigate what happens when baking soda mixes with vinegar.
Small bottle
Balloon Vinegar Baking Soda.
1. Pour some vinegar into a bottle.

2. Use a funnel to tip baking soda into a balloon.
3. Carefully stretch the balloon over the bottle so that the baking soda drops in.

4. See what happens. Talk about why.

Conclusion: The baking soda and the vinegar mixed together causing a chemical reaction. This reaction created a gas called carbon dioxide (the same gas that we breathe out). This gas blew the balloon up. WOW, Science is COOL!
