CHEMICAL REACTION EXCAVATION
In this fun and easy excavation activity for kids, we’re going to use a chemical reaction excavation that fizzes, bubbles, and pops to uncover our treasures we have hidden inside.
- 2 ounces of lemon juice
- 1 teaspoon of baking soda
- One square of toilet tissue
- Ziplock sandwich baggie
- Small items to "excavate" that can fit in the square of tissue. I like to use small tumbled stones. Little plastic aliens, dinosaurs, or other toys are also fun.

- Put the baking soda in the toilet paper square.
- Add the small item to discover in the baking soda.
- Fold the paper around the baking soda and tape it closed.
- Pour the two ounces of lemon juice into the baggie.
- Now carefully fill the baggie about a quarter of the way full with water.
- Head outside to an area that can get messy.
- Drop the packet of baking soda into the baggie.
- Quickly seal the baggie securely closed.
- Stand back and wait for your chemical reaction excavation to pop and reveal the hidden item.
I hope you enjoyed this super quick tutorial and had fun creating your own Chemical Reaction Excavation to investigate and explore. These excavations are very easy to make and a lot of fun!
Pro tip: Use this activity to create some excitement around discussions or lessons about acids and bases, chemical reactions, kitchen science experiments and more!
