In this multi-part activity learners examine non-point water pollution.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.

In this activity, learners design a flag for a chosen or assigned planet. The instructions include information about flags on Earth, and a list of flag references.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

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 examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

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 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 will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

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 how nanotechnology is being used to create new types of protective fabrics.

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

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
