In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

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

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

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

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

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
