Lava Lamps

First grade chemists began lab by observing a real lava lamp. We watched the hot wax rise and then fall after it reached the top and cooled. It reminded us of the way that yeast use budding to reproduce.

Then first grade chemists made lava lamps with a holiday twist! We used a solid and two liquids to create a gas.Why didn’t the water and oil mix? Why is the water at the bottom of our bottle? Why did the color fizzer color the water, but not the oil? What created the bubbles in our lava lamp?  Why did they rise and then fall ? Click here for directions and for more information. Vocabulary included beaker and funnel.

We placed a flashlight under the bottle, and watched it glow!
