In this activity, learners explore the possibilities of clay as a natural material.

This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.

This outdoor activity/field trip requires a place where minnows swim, such as a local pond or brook.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

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.

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit
