The dots above (representing molecules) show one reason why one material has more or less density than another. Can you see how the molecules of the densest material, water, are more closely spaced ...

👉 Watch the video of Sarah’s school science experiment at Forester Elementary here! Hello parents, teachers and students! If you’re looking for a fun way to explore the physical properties of density ...

The Science Siblings, Adam and Paige Jacobson, recruited 4-year-old Tukker and 2-year-old Jayger for a density experiment. They tested whether fruits and veggies float or sink in a bowl of water.

This easy science activity demonstrates the difference in density between hot and cold water. It can be a bit messy so you may want to try this outside. We're joined by BASF employee, Casey, and his ...
