This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this activity on page 4 of the PDF (Get Cooking With Chemistry), learners investigate ingredients that combine to produce gas bubbles.

In this activity, learners explore dinosaur fossils and a dig site. Learners work in groups to analyze a dig site map and match bones to a skeletal drawing of Kelsey (a Triceratops).

In this activity (1st on the page), learners conduct a series of tests to find out which of their hands is more dominant. In other words, are they right-handed or left-handed?

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 explore how the hull shape impacts a ship's performance and stability.

Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

In this physics activity (page 10 of the PDF), learners will make a can that will roll back after it has been rolled away to observe the interactions of kinetic and potential energy.

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

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.

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this crime science activity (on page 2 of the PDF), learners will explore the uniqueness of fingerprints. The will learn components of fingerprints as well as why fingerprints are left behind.

In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.
