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

Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

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.

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

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 engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.

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

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

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

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 the design of tall structures such as skyscrapers and telecommunication towers.

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 engineering design challenge, learners build an air-powered spinning machine.

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.
