In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

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.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this activity, learners are invited to imagine the park of their dreams!

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this activity, learners examine nanoscale structures of common things.

In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity, learners use maps to locate the Arctic region and use a word game to discover the types of resource people need to survive in the extreme climate.
