Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

Engineer and cartoonist Rube Goldberg is famous for his crazy machines that accomplish everyday tasks in overly complicated ways.

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

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 play the role of materials engineers as they test the flexibility of different materials.

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.

Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

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.

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.

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

Play with your food while learning about engineering! Build a spaghetti bridge, then test its strength by piling on the marshmallows, raw spaghetti, raw linguine and coins.

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

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.
