Science Experiment: Elephant Toothpaste
Aim: To see what it’s like when using different kinds of bottles and how the toothpaste would appear.
Hypothesis: If we got a smaller bottle, then the toothpaste would shoot farther
Ingredients:
- A clean 16 ounce (473 ml) plastic soda bottle or a water bottle.
- 20-Volume hydrogen peroxide liquid
- 1 Tablespoon (15 ml – one packet) of dry yeast
- 3+ Tablespoons (15 ml) of warm water
- Dishwashing liquid
- Food colouring
- Small cup
- Funnel
Independent variable: Yeast, Water, hydrogen peroxide, dishwashing liquid.
Dependant variable:Different types and sizes of bottle.
Method:
- Get a bottle.
- Put hydrogen peroxide in the bottle.
- Put dishwashing liquid in the bottle.
- Mix thoroughly.
- In a separate cup put of dry yeast.
- Put warm water in the separate cup.
- Mix thoroughly
- Put the yeast in the bottle.
What was my science project about? It is about Elephant toothpaste.
What was my hypothesis? If we change the bottle, then the toothpaste would come out differently.
Was it correct? why or why not? Yes, when we used a smaller bottle it shot up way faster than when we used a 1.5L bottle.
What were my variable? My independent variable were yeast, water, hydrogen peroxide and dishwashing liquid. And my dependent variable were different types and sizes of bottle.
What did I find out? I found out that we need more hydrogen peroxide and yeast more so that we can measure how far the toothpaste goes.
