Step-by-Step Procedure

  1. 1

    Place the plastic cup in the center of the tray.

  2. 2

    Fill the cup halfway with baking soda.

  3. 3

    Add a few drops of food coloring to the baking soda.

  4. 4

    Squirt a teaspoon of dish soap into the cup.

  5. 5

    Slowly pour the vinegar into the cup.

  6. 6

    Watch as the mixture begins to fizz and overflow like a volcano.

  7. 7

    Observe the bubbles and foam created by the reaction.

  8. 8

    Repeat with different colors for more eruptions.

Expected Results

Adding vinegar to baking soda will cause a fizzy eruption as carbon dioxide gas is released. The dish soap will create foam and bubbles, enhancing the volcanic effect.

Variables

Independent Variable

Amount of vinegar added

Dependent Variable
