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 lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

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 activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
