Little Tuskers Tremendous Toothpaste
Question: How will a mixture react when dry yeast is combined with hydrogen peroxide and dish soap?
Hypothesis: We believe that the stronger the concentration of hydrogen peroxide(H2O2), the quicker a reaction will take place. The higher the concentration of hydrogen peroxide in the solution, the greater the amount of Little Tuskers Tremendous Toothpaste will be produced.
Procedure:Detail steps so anyone can reproduce this at school or home Use a numbered list
Special Needs: A sink is needed to wash the trays and bottles before conducting the experiment again. |

The Science Behind It
The foamy elephant toothpaste will be created by the decomposition (the break down of one substance into it's component parts) of hydrogen peroxide(H2O2) into Hydrogen and Oxygen. The yeast acts as a catalyst (a substance that changes the rate which a chemical reaction takes place) to remove the oxygen from the hydrogen peroxide. The more oxygen present in the hydrogen peroxide, the quicker the reaction. This reaction not only happens very quickly but also produces bubbles and creates heat. This creation of heat is called an Exothermic reaction.
Conclusions
In conclusion, our hypothesis was correct. The 9% hydrogen peroxide reacted quicker than the 6% or 3% hydrogen peroxide. The 9% hydrogen peroxide also yielded the greatest amount of Little Tuskers Tremendous Toothpaste. The 6% hydrogen peroxide reacted faster and produced a greater amount of Little Tuskers Tremendous Toothpaste than the 3% hydrogen peroxide, but slower and less than the 9% hydrogen peroxide. The 3% hydrogen peroxide reacted the slowest and produced the least amount of Little Tuskers Tremendous Toothpaste.
