Hello parents, teachers and students!
Are you looking for something fun to do at home that has a little bit of science behind it?
Well, learn how to make elephant toothpaste at home with Meteorologist Sarah Spivey and her awesome assistant, David Sears!
So why exactly do you think the reaction occurs? Let us know your thoughts in the comments below. Be sure to check out GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it. To view, click on the video player above.
HERE’S WHAT YOU’LL NEED
DO THE EXPERIMENT
HOW IT WORKS
This is a great example of chemistry! In this experiment, yeast acts as a catalyst. A catalyst speeds up a chemical reaction. In this case, the yeast helps break down hydrogen peroxide into water and oxygen. The dish soap captures the oxygen bubbles and makes for a very cool-looking reaction.
Here’s the chemical reaction, if you’re curious: 2H?O?(hydrogen peroxide) -> 2H?O(water) + O?(Oxygen)
SCIENCE WITH SARAH
If you’d like Sarah and David to come to your school and conduct a science experiment live on KSAT, email sciencewithsarah@ksat.com.
