This experiment demonstrates how water at different temperatures has different densities, creating beautiful layering effects. You'll see how warm and cold water interact and learn about density ...

record the mass accurately measure and observe the mass and the volume of the different objects use appropriate apparatus and methods to measure volume and mass and ...

Create a colorful tower of liquids that stack on top of each other based on their densities. This experiment demonstrates how different liquids have different densities and why some liquids float ...

Mice lived aboard the International Space Station for 37 days, and experiments gave insights into how humans lost bone density in microgravity.
