In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

In this activity, learners explore Charles' Law in a syringe.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.
