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

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

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 is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this environmental health activity, learners investigate their own vital lung capacities.

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.).

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

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 create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

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 build their own construction cranes using tongue depressors and pushpins.
