In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

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.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

Learn how to construct a light box by following simple figures and instructions. This guide includes tips on how to assemble a light box; related activities are featured in separate resources.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.

This fun and simple activity is a rubberband rocket design challenge! Learners will explore how tail fins can help to stabilize a flying object, while also exploring potential and kinetic energy.

In this activity, learners explore the engineering behind the conveyor belt and consider the impact this invention has had on transportation and the coordinated shipping and delivery of goods.

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
