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.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

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 explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

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 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 (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 field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this hands-on nature activity, learners observe the emergence of leaves and flowers. Branches from trees and bushes are collected in the early spring, brought indoors, and placed in water.

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

This is a comprehensive lesson plan on page 85 for a group cleanup trip to a local beach, lake or stream. Learners keep track of the types and amounts of trash picked up and analyze this information.

This activity (located on page 3 of the PDF under GPS: Temperate Rain Forest Activity) is a full inquiry investigation into biodiversity of a given habitat.

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

In this family or group activity, learners create a nature journal by visiting a local nature center or backyard, observing creatures in their natural habitats, and sketching what they see.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
