In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.

In this activity, learners consider how oil spills behave in the ocean and what impact they have on marine wildlife.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this health activity (on page 3 of the PDF), learners will learn about the body‘s defenses against invasion from tiny particles.

Using simple, inexpensive items, learners build and test submarine models.

In this activity (page 37 of the PDF), learners observe, on a prepared slide, muscle and spinal cord cells from a rat.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

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 on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.

This is a hands-on activity about the physics of tennis. Learners will discover that physics plays a big part in tennis, no matter what their skill level might be.

In this archaeology activity, learners make observations and conduct an experiment to demonstrate the effect saltwater has on artifacts.

In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.
