Today we created lava lamps in class to look at density of different liquids. We used alka seltzer tablets to get the liquids moving. Watch the videos below and answer these questions:
1. How does the lava lamp help us understand density?
2. Why does the water rise? Why does the water fall?

The project was so fun I’m going to try it again just for fun!
I loved that project . I have the bottle sitting on my dresser.
