Students design and create their own air-powered rockets, in this hands-on activity.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

Learners construct an electricity-generating wind turbine out of a plastic bottle.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this activity, learners build an old-fashioned paddle boat out of simple materials.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
