In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.

This activity (located on page 3 of the PDF under GPS: Cave Swallows Activity) is a full inquiry investigation into bird behaviors.

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 math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

In this activity (on page 1 of the PDF under SciGirls Activity: Soccer Ball Kick), learners will investigate the transfer of energy using sports equipment.

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.

In this activity (located on pages 9-14 of PDF), learners visit a cemetery to examine the distinguishing characteristics of rock weathering.

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

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this activity, learners explore rocketry and the principals of space flight.

In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

In this math lesson, learners participate in several activities where they apply measurement skills.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

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

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.

Build a fruit fly trap out of a 2-liter plastic bottle and some rotten fruit! Fruit flies are easy to catch in warm weather. Once you catch some, you will be able to see their life cycle up-close.

In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.
