In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners are invited to imagine the park of their dreams!

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

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

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

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.

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 explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

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.

In this activity, learners will engineer three different parachutes to test how well each one works.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

In this activity, learners simulate whale echolocation. Learners experience echolocation by wearing blindfolds, while another learner makes snapping noises in front of, behind, or to the side of them.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Learners develop an understanding of air pressure in two different activities.

In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.
