In this activity, learners collect worms and then observe how they move.

In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.

In this activity, learners explore the different heating properties of soil and water.

This is an outdoor activity designed to demonstrate evolution of feeding behavior in flocking, schooling or herding animals that maximizes allocation of food resources and enhances survival.

In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

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 model erosion using a clear shoebox and sand or soil.

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 math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

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

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.
