Today we heard from the scientist. And she had some very interesting things to share! Hayleigh wanted to know what would happen when you mix baking soda and vinegar. A previous scientist of ours, Tessa, shared a similar experiment on Halloween so we were convinced we knew the results. Turns out we shouldn't jump to conclusions.
Here's our scientific method...
Question: What happens when you mix baking soda and vinegar in a bottle with a balloon on top?
Materials: baking soda, vinegar, funnel, balloon
Procedure: Pour vinegar into a bottle. Use a funnel to pour baking soda into a balloon. Place the balloon over the opening of the bottle. Shake in the baking soda. Prepare to be amazed.
These were our hypotheses:
(a) The mixture will bubble up. (5)
(b) The mixture will create Carbon Dioxide. (4)
(c) There will be a small explosion. (9)
Here's the results:
The baking soda and vinegar mix and create gas through a chemical reaction. The gas expands and needs somewhere to go, so they fill up the balloon. It didn't explode, but you could use a lot of baking soda and vinegar if you want to hear a pop.
Thanks Hayleigh! We may have to try this one at home!
