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

In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this activity, learners will learn how to knit using only their hands. Learners will explore patterns and fabrication as well as develop fine motor skills and patience through this activity.

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

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

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!

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

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

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 interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

In this activity, learners build water-propelled engines from soft drink cans.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners gain a better understanding of how household/school waste breaks down in a landfill. Learners collect trash and then create miniature landfills in 2-liter bottles.

In this activity, learners make self-assembled polymer spheres.
