                    Lava Lamp

          Chemical Energy

We learned how Oil is less dense then water

We learned how the Alka Seltzer is a combination of sodium bicarbonate, aspirin and a citric acid. The hydrogen reacts with the bicarbonate to produce carbon dioxide, which appears as bubbles in the lava lamp.

The gas bubbles rose up and took some food coloring and water with them to the surface. Once all the gas bubbles have escaped then the water and oil separate again.
