Description
Underwater Volcano Science Experiment | Density & Water Temperature Lab Activity
Science Topic: Density
Can you create an underwater volcano?
In this exciting Underwater Volcano Science Experiment, students investigate how water temperature affects density as they watch hot, colored water rise through cold water.
Students will make predictions, conduct a hands on experiment, record observations, and use their findings to understand why less dense fluids rise while more dense fluids sink.
The colorful swirling water creates a high wow factor while giving students a memorable way to see density in action!
