Simple Science With a Balloon

Learn About Carbon Dioxide

This year, my youngest is really getting in the groove of Science.  Because he loves hands on learning, I am working extra hard to help grow his love of learning by allowing him some freedom in what he is learning, while also following in the steps his Father and I think he should take in order to gain a good foundation in God and in his education.

One of the things that really intrigues my little guy….is gas. He thinks anything passing gas is absolutely hilarious.  If you have boys, you know what I’m talking about.

So, I found this nifty (and easy) experiment that helps identify how carbon dioxide can be created using some simple supplies.

Supplies for Balloon and Carbon Dioxide Experiment

 

Supplies

  • Yeast (about 1 tsp)
  • sugar
  • warm water (not hot!)
  • plastic (or glass) bottle
  • Balloon

Place about two inches of warm water in the bottle.  Add your yeast and sugar.  Place the balloon over the opening of the bottle.  She the bottle/jar just a little….and watch.  Your little guy (or even girl) will think it’s a lot of fun to watch the balloon blow up.  It may take a while…but it will.

 

Balloon Expands as Carbon Dioxide is created

What’s happening?

The yeast is eating the sugar and creating Carbon Dioxide!!!

What easy experiment have you had fun with recently?

  1. It looks like your experiment worked. We did a similar one using vinegar and baking soda. We did not get the results that we wanted.

    • Karen, Hmmm…..that sounds similar to our volcano experiments. If you do this one, make sure you use warm water…not hot so you don’t kill the yeast.

  2. Love it gonna pin it. We are doibg a lot more hands on stuff to this year. This will go along great with our plant unit study that is coming up.
