Brainstorming Ideas 1

Brainstorming Ideas 1

This Experiment is common known The Elephant Toothpaste Experiment

Research Question: Does the amount of hydrogen peroxide used in the experiment affect the speed of reaction between the catalyst and enzyme?

Materials: Funnel, measuring beaker, hydrogen peroxide, instant dry yeast, dish washing liquid, stopwatch, food coloring, 500ml mineral water bottle

Hypothesis: The more the amount of hydrogen peroxide used the slower the speed of reaction

Variables:
Dependent:Time taken for reaction to be finished

Independent: Amount of Hydrogen Peroxide used

Constant: the amount of soap used, the amount of yeast used, the amount of water used, the amount of food coloring used, the volume and shape of the bottle, the temperature of the water used.

Short summary of research done on the area of investigation:
- When a reactant comes into contact with a catalyst/enzyme, a reaction takes place
- When the experiment of the elephant toothpaste takes place, an exothermic reaction takes place
- The yeast , that acts the catalyst, removes oxygen form the hydrogen peroxide thus creating bubbles that leads to foam.
- The foam produced comprises of soap, oxygen and water.
