This easy kitchen experiment is a blast!
Hover over each Learning Benefit below for a detailed explanation.
What you need:
- large paper plate
- two 3 oz. paper cups
- aluminum foil
- scotch tape
- 2 tablespoons of water
- 1 tablespoon of baking soda
- 2 tablespoons of vinegar
- large baking pan
What to do:
Build your "volcano"
- Tape the bottom of one of the cups to the middle of the paper plate.
- Tear off a piece of foil large enough to cover the cup and plate completely.
- Place the foil over the cup and plate and turn the foil under the plate edge. Tape foil in place.
- Poke a hole through the foil into the middle of the cup.
- Tear strips in the foil so that it may be easily folded down along the inside edge of the cup.
Help your volcano erupt!
- Place your volcano in the pan (an eruption can get messy!).
- Fill the volcano cup with the 2 tablespoons of water.
- Stir in the tablespoon of baking soda until it dissolves.
- Measure the 2 tablespoons of vinegar into the other paper cup.
- Ask your child to predict what will happen when you pour the vinegar into the volcano. Pour it in and watch it erupt!
- Discuss the reaction. The "lava" bubbles that erupt are filled with carbon dioxide. The carbon dioxide is a gas that forms when an acid — the vinegar — reacts with a base — the baking soda.
