Elephant Toothpaste Galore!

This Friday, October 24th, Sisters4Science at Frederick Funston Elementary School had the awesome experience of making elephant toothpaste. Now, it’s not really elephant toothpaste but with the amount that the experiment actually produces makes it seem that it is elephant toothpaste. Project Exploration’s Program Manager, Jaclyn Carmichael, was our scientist of the day! She conducted the experiments with the girls. At first, we all did the experiment together. The materials were: hydrogen peroxide, color dye, dry yeast, dish soap, soda bottle, and water. When we mixed them all together, the foam came shooting of the bottle rapidly. The girls were absolutely amazed!

One of the ingredients of elephant toothpaste, dish soap! Who knew?!

They went into three groups and each group altered the amount of a material from the experiment. One group did more yeast, another did more hydrogen peroxide, and the last group did the less yeast.

Our group who added extra yeast and made their toothpaste yellow!

The group who did the most hydrogen peroxide resulted being the one with the most elephant toothpaste. I think the girls had the time of their lives!

The results:

Next week, we will have another scientist that was going to do experiments related to Halloween! Oh the fun!!
