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

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

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

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.

In this activity, learners explore the engineering and principles behind working elevators.

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

In this activity (page 10 of the PDF) learners will explore the historical progression of siege weapons to gain an understanding of how the addition and modification of parts can change the efficiency

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

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 activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
