In this engineering activity, challenge learners to invent a water filter that cleans dirty water.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

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

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.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

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.

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

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 use a soda can to decode a secret message. Learners wrap scytale (pronounced ski-tally) code around a can and challenge friends to see if they can crack the codes.

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.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

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