In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

In this activity, learners investigate the movement caused by dispersion. Learners discover that dispersion is the random movement of objects.

In this activity, learners investigate the properties of graphene and graphite.

Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.

Light painting is a creative activity that involves creating striking images and illusions using a camera, a light source, and a little practice.

In this activity (on page 2 of the PDF under GPS: Light and Color Activity), learners will see the illusion of colors produced by a rotating black and white image known as Benham’s Disk.

This is an activity about turbidity, or the amount of sediment suspended in water.

This activity has learners observe water and compare it to other liquids.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

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

This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.

This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.

Learners investigate how the temperature of water affects its density.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

In this activity, learners explore how engineering has developed various means to remove impurities from water.
