In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

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

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

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 explore dinosaurs and fossils by creating a diorama.
