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

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

In this water activity, learners discover ways to move water across the water table.

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

In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.

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.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

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

In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

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

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity, learners construct a home-made journal with simple, everyday materials.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners use found natural materials to create a water haven for bees and other insects.
