In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this activity, learners investigate density as they discover how liquids separate to form density layers. Learners discover what happens when they add syrup, cooking oil, and water to a jar.

Learners investigate how the temperature of water affects its density.
