Aim: to make a volcano we created erupt using chemical reactions
Hypothesis: I think that the volcano with definitely erupt when we add the chemicals.
Equipment: Our Volcano, Baking soda, vinegar, food colouring, dish washing liquid
Method: first we made and painted the volcano add chemicals to make the volcano erupt then clean up after
- warm water
- dish washing liquid
- red or orange food colouring
- baking soda
- vinegar
- Pour warm water into the volcano until it is 1/2 to 3/4 of the way full.
- Add several drops of food colouring.
- Add a squirt of detergent. This helps the ‘lava’ foam up and flow.
- Add a couple of spoonfuls of baking soda.
- When you are ready to start the eruption, pour vinegar into your volcano.
- You can recharge the volcano with more baking soda and vinegar.
Note: If you don’t have vinegar, you can use another acidic liquid, like lemon juice or orange juice.
