Volcano

 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

1. Pour warm water into the volcano until it is 1/2 to 3/4 of the way full.
2. Add several drops of food colouring.
3. Add a squirt of detergent. This helps the ‘lava’ foam up and flow.
4. Add a couple of spoonfuls of baking soda.
5. When you are ready to start the eruption, pour vinegar into your volcano.
6. 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.
