This lesson focuses on how materials behave differently as their surface area increases.

In this fun hands-on activity learners explore a simple machine: the lever. What happens to a load when you multiply the length of a lever? Find out here!

In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

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

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.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

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 explore engineering package designs that meet the needs of safely shipping a product.

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

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

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

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

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

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

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.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.

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