Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

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

In this activity, learners explore the engineering and principles behind working elevators.

In this activity, learners explore watercraft engineering and sailing.

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

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 activity, learners explore how engineering has developed various means to remove impurities from water.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.
