This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

Learners play the role of materials engineers as they test the flexibility of different materials.

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

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

Learners develop an understanding of air pressure in two different activities.
