This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.

In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

This activity (on page 2 of the PDF under SciGirls Activity: Malformed Frogs) is a full inquiry investigation into using indicator species to assess the health of an environment.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

In this outdoor activity and/or field trip, learners investigate the behavior of hopping animals.

This is an activity to do when there is a solar eclipse!

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.

In this activity (on page 2 of the PDF under GPS: Biodiversity Activity), learners will pair up and take a notebook outdoors to a selected location to observe and record a list of living things that t

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

This activity (on page 3 of the PDF under GPS: Biodiversity Activity) is a full inquiry investigation into biodiversity.

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.
