Play Dough Volcano Eruption Experiment
This experiment is about chemical reactions that take place between baking soda and vinegar and checking what makes the reaction happen quickly.
Step-by-Step Instructions
1
Place the plastic in the centre of a cardboard base.
2
Use play dough or clay to build your desired volcano mountain shape around the bottle, make sure to leave the bottle opening uncovered.
3
Add food coloring to the warm water in the bottle.
4
Then add the drops of dishsoap.
5
After that, add the 3 tablespoons of baking soda to the mixture in the bottle.
6
When you are ready add the vinegar to the mixture and watch your volcano erupts!
Observations
When we used more baking soda, the reaction was faster with the same amount of vinegar.
Hypothesis
If we use more baking soda the reaction will be faster.
Conclusion
My hypothesis was correct because the reaction is 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.
