Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.

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 will engineer a new shape and use it to create a new pattern with no wasted space.

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.

Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.

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.

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

In this online activity, learners find out whether they are smart enough to survive as a plant.

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.

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

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.

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.

In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.

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 build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

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

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.
