Instructions
Today, you're going to explore the fascinating world of chemistry by creating your very own DIY volcano! Follow the steps below to learn about the reaction that causes the volcanic eruption.
Materials Needed:
- Baking soda
- Vinegar
- Dish soap
- Food coloring (optional)
- A container to hold your volcano (like a plastic bottle)
- A tray or a large dish to catch any overflow
Steps:
- Construct your volcano: Use the container (plastic bottle) as the center of your volcano. You can shape it with clay or play-dough around it to make it look like a volcano.
- In a bowl, mix 2 tablespoons of baking soda with a few drops of dish soap and food coloring. This will be your "lava".
- Pour the "lava" mixture into the volcano.
- In another container, measure out 1/2 cup of vinegar.
- When you're ready, pour the vinegar into the volcano and watch the eruption happen!
Let's Learn!
Answer the questions below to learn more about the chemistry behind your volcano.
