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

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

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 engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

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

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

In this activity, learners explore how engineers work in a team to solve problems.

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

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

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.
