Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

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

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

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

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

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

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.
