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

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

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

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.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.
