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

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

Learn about friction and kinetic energy with this cool spinning toy.

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.

In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

In this activity, learners explore the possibilities of clay as a natural material.

In the kitchen, learners can perform their own density investigation.

"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?

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.

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

In this activity, learners construct a small "air cannon," and use its airflow to put out a candle (lit with the help of an adult).

In this activity, learners will make their own "ball bearing" with two jar lids, marbles, and some household supplies.

In this activity, learners will make predictions and experiment with different objects to see if they sink or float.

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.

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.

This is an online game recreating the longest ever (at that point in time) freefall jump by Air Force Captain Joe Kittinger.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.
