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

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

In this activity, learners build water-propelled engines from soft drink cans.

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

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 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

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

In this hands-on engineering project, kids use two simple machines, levers and inclined planes, to construct their own pinball machines.

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.

Students design and build their own parachutes in this hands-on engineering project.

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.

In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.

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.

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 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, challenge learners to make a "grabber" that can pick up trash. Learners use simple materials to create pinchers that can grab small items.

In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

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