Playdough Volcano Eruption Experiment
This experiment is about chemical reactions that take place between baking soda and vinegar in a volcanic set-up and checking what makes the reaction happen quickly.
Step-by-Step Instructions
1
Place the plastic bottle in the centre of a cardboard base.
2
Use playdough or clay to build your desired volcano mountain shape around the bottle, make sure to leave the bottle opening uncovered.
3
Add food colouring to the warm water in the bottle.
4
Then add the drops of dishsoap.
5
After add the 3 tablespoons of baking soda to the mixture.
6
When you are ready add the vinegar to the mixture and watch your volcano erupt!
Observations
When we added more vinegar, we saw that the reaction happened quickly.
Hypothesis
If we use more baking soda the reaction will be faster.
Conclusion
Our hypothesis was correct because the reaction was faster when more baking soda is added. I learned that if you want the reaction to take time before it erupts use a small amount of baking soda otherwise the reaction will happen very quickly.
