In this activity, learners model ancient lunar impacts using water balloons.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

In this activity, learners make a photographic image—without a camera!

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

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

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

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

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

In this activity, learners explore the concept of insulation by trying to keep Olaf the Snowman from melting. This activity encourages critical thinking and problem solving.

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.

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In this activity, learners will decide together on a question about how far, long or high the group could reach together.
