Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

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.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

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

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

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.

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

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

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

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

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.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.
