Everybody loves boomerangs! In this activity about force and motion, the learners will experiment with boomerangs and explore how they work. This is a great activity to get learners up and moving.

In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.

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

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

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.

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.

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 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.

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 activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

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

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.
