In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

Learners design their own experiment to investigate how pollution diffuses through ground material.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

In this activity, learners will engineer three different parachutes to test how well each one works.

This magic trick is based on how computers detect and correct data errors.

In this activity, learners will make a marionette puppet and put on a show. Learners will explore color, design, fabrication and storytelling through this activity.

In this activity, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.
