In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.

This lesson focuses on how materials behave differently as their surface area increases.

Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

In this activity, learners build a carousel toy that spins when pushed down.

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

In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

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.

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, learners participate in a scavenger hunt, searching for and recognizing minerals and products that contain minerals.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.

In this activity, learners explore the relationship between electric charges and magnetic fields.

This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.
