Leticia's Vinegar and Baking Soda Volcano

On an exciting day, when my class was learning all about experiments, my teacher (Miss Williams) let all of us bring an experiment. I brought my experiment two days ago. It was a volcano (but not a real one). It is one that is made of vinegar and baking soda. This is how you make it:

You will need:


  • An egg shell with a small hole on top
  • Vinegar
  • Baking Soda


Instructions:


  1. Put 3 teaspoons of baking soda into the egg shell.
  2. Pour the vinegar into the egg shell.
  3. Stand back and watch what happens!




The vinegar and the baking soda make a reaction that creates bubbles and a thick foam comes erupting out of the eggshell. It is a cool experiment! All of the people in my class enjoyed watching the volcano erupting.

    Hello Leticia & Rm 21
    I like the way you clearly explained how this experiment worked. This is very cool that room 21 is doing experiments.
    I'd like to know...
    Why did you choose this experiment?
    What did you learn from this?
    Keep having fun doing experiments!
