Learners measure irregularly shaped bones using a variety of measurement methods and tools. Then, they measure again using standard conventions and metric tape measures.

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

This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.

In this activity, learners discover that sand is the major ingredient in glass.

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 design a device to solve a problem: how to get a ball out of a drain pipe.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this art meets chemistry activity, early learners discover the almost magical absorbent properties of salt while creating ethereal watercolor paintings.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

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

In this activity, learners discover how sediment is affected in an oil spill. Learners investigate the differences between heavy and light oil as well as the differences between different sediments.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

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

In this activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.
