The St. James STEM club made DIY lava lamps during its March meeting!
Our STEM Club is made up of students from grades 3-5. Each month we do a project to explore a different topic in science. In March, we made DIY lava lamps. Each student took a new water bottle and drank half the water. Then they decorated the outside and added food coloring to the water.
We filled the rest of the bottle with oil and made two layers. The color stayed in the water layer.
When we shook the bottles hard enough, the layers mixed together for a little while.
Alka-seltzer tablets made the water bubble up into the oil. Just like a lava lamp!
Putting a light underneath made it look even better!
