Lava In A Cup!

-By Kelsey Richmond and Faith Fickey

The Purpose(:

We did this project because it seemed like something fun to do and it was something really easy to experiment on.!


  • 14 grams of salt
  • 1/4 cup of vegetable oil
  • Water
  • Red Food Coloring
  • Clear Plastic Cup


    1. Fill the glass up about ¾ full of water

    2. Add about 5 drops of red food coloring.

    3. Slowly pour the vegetable oil into the glass.

    4. pour 14 grams of salt on top of the oil.

    5. watch the reaction

    6. write down your observation

    7. wait for the reaction to end.

    8. add 28 grams of salt (2 teaspoons)

    9. watch the new reaction

    10. write down your observation

    11. compare the two reactions


The experiment ended up resulting the same as the hypothesis. The second time the the experiment was done lasted longer than the first because two times the amount of salt was used the second time made the reaction time about two times longer than the first reaction time. The experiment could of been better by repeating it over and over and finding the average amount of time between the two times it was experimented . Would it of made it making a graph easier? Does finding the average amount of time it took make comparing them better?
