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
If we use more baking soda the reaction will be faster.
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.
Materials Needed
  • 1/2 Cup of vinegar
  • A plastic bottle (preferably small to medium)
  • 2 drops of dish soap
  • 3 tbsp of baking soda
  • Food colouring (for a lava effect, optional)
  • 150ml of warm water
  • A tray (to catch the eruption)
  • Play dough or modelling clay
⚠️ Safety Notes
  • Have parents supervision when using warm water.
  • While vinegar isn't harmful, avoid getting it in the eyes.
  • Do it outside to avoid mess inside.
  • Clean up immediately after.

What would happen if you used cold or iced water instead of warm water?
