In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

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

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod
