Ingredients Hydrogen Peroxide Detergent Yeast Food Colouring
Hypothesis Tane thought that the red food colouring would change colour. India-Grace thought it would explode. Cam thought it would make a mess. Victoria thought that the red food colouring would turn a rainbow colour.
Catalyst Zavierguessed that the yeast was the catalyst. A catalyst speeds up the reaction.
The Steps Put plastic bottle in the middle of a pan. Mix 2 tablespoons of warm water with 1 teaspoon of yeast.
The Steps Put ½cup of Hydrogen Peroxide in the bottle (6%) 4-5 drops of food colouring. A squirt of dish washing liquid.
Ella felt the bottle . It was warm. The bottle was warm because the reaction releases energy as heat.
We loved feeling the froth. It smelt like soap.
