In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity, learners investigate the olfactory system by conducting several experiments.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, pairs of learners will create two make-believe dig sites by burying chicken bones in plaster of Paris--a powder that hardens when wet.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

In this activity, learners explore the engineering and principles behind working elevators.

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.

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.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
