Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin

In this activity, learners explore how boats are engineered to achieve speed.

Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

Using simple, inexpensive items, learners build and test submarine models.

In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners design a bungee jump for an egg using nylon stockings.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.
