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.

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.

This activity has three story puzzles learners can solve to learn about life in the Arctic.

In this activity, learners make homemade journals featuring seashell rubbings. First, learners transfer the texture of a seashell onto a piece of paper using a crayon.

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, learners use information gathered from a variety of sources to design and make their own insect.

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 separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.

In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

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.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

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

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.
