In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

These three short activities challenge groups to fit objects through paper and index cards: "Slots" presents the challenge for one learner to figure out which objects fit through a hole cut by another

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

In this activity, learners compare different types of salt crystals under a magnifying glass.

In this activity (11th activity on the page), learners use their sense of touch to identify matching pairs of objects hidden in bags. Learners can also play this game with partners.

In this activity, learners investigate static electricity using everyday objects at four different stations.

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

This is an activity about circular motion. Learners will explore the laws of motion and force by observing circular motion.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

Create a “Find Someone” list, with about 10 items, each containing a shape, number, or measurement. Can you find someone in the group with hair about 4 inches long? Someone wearing parallel lines?

In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.

In this activity (pages 7-16), learners model various crystal structures with LEGOs. This activity also contains additional links that explain how to create other crystal structures.
