Here is a hands-on activity in which junior scientists put air into a balloon to create a closed system. They measure its circumference, warm it in hot water, and then remeasure its circumference to discover how temperature affects the...

How fast does water cool? First fifth graders will draw a line on a graph that predicts how fast they think water can cool from boiling. Then they plot the actual data on the same graph to see if their estimate was correct.

Here is a planet activity in which learners read about organic molecules detected through spectral lines of the planet Osiris. They calculate the mass, the volume and the densities of common ingredients for planets including Osiris and...

In this metric worksheet, students complete 28 different metric calculations consisting of density, volume, mass, length, temperature, and time.
