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

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

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

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

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 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 design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

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

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 the devices used over time to measure changes in temperature.

In this activity, learners will explore how and why weight distribution works.

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

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

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

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