Final Chemistry and Salts experiment- Elephant Toothpaste
- 1/2 cup 20-volume hydrogen peroxide liquid
- 1 Tablespoon (one packet) of dry yeast
- 3 Tablespoons of warm water
- Liquid dish washing soap
- Food coloring
- Small cup
Research Question: What temperature of water would be the best for the the elephant toothpaste?
IV: temperature
DV: how quick the foaming is being produced
Hypothesis: As the IV increases, then the DV will be faster/quicker.

Discussion:
Even after try three times, my experiment didn’t give me any results. However, Adam Savage once said; “In the spirit of science, there really is no such thing as a ‘failed experiment’. Any test that yields valid data is a valid test”. Something that worked with my experiment is that even thought there wasn’t any ‘foaming’, I could see that the mixture was going up. I think that next time I should try putting in more yeast. In addition to that, I could also put the exact amount of hydrogen peroxide needed. Finally, next time, I will try to follow the direction word by word o I don’t make mistakes.
Conclusion:
Based on my data, I can conclude that cold water might be a better solution for this experiment. That is because I tried my experiment with warm water, hot water, and room temperature water and I got no results for each of those. Next time, I should make sure to also use cold water
