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).

Learners observe working lava lamps to understand how they work (included in PDF link).

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

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

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

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