In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

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.

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 build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

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

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

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.

Learners investigate how drag affects the falling rate of objects.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.
