Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

In this activity, learners will be able to measure themselves in nanometers. A nanometer is a billionth of a meter, a unit of measurement used in nanotechnology.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this activity, learners search for various kinds of items made from minerals around their home or school, including toothpaste, wall paint, kitty litter, and bricks.

No glue is needed for learners of any age to become marshmallow architects or engineers.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

Learners make self-assembled polymer spheres as a model for the lipid nanoparticles found in COVID-19 mRNA vaccines.
