Lava Lamp Learners

Latest News

We have had the chance to do some fun scientific experiments at Casserly House After School, including a gummy bear osmosis experiment, exploring air resistance by making paper parachutes for LEGO people, and most recently, we made at-home lava lamps to learn about density! Students had the chance to up-cycle plastic water bottles to create their own lava lamps using water, oil, food coloring, and Alka-Seltzer tablets. They loved watching the water sink to the bottom and the Alka-Seltzer ignite the solution into a reaction. Not only did we learn an important lesson of reusing plastic, we also learned that water has a higher density than oil, causing it to sink to the bottom and separate from the oil. We loved seeing their minds churning and faces light up. Looks like we might have some chemists in the making!
