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

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

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

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
