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

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.

Learners play the role of materials engineers as they test the flexibility of different materials.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this physics activity, learners will investigate the strength of egg shells.

In this activity, learners make self-assembled polymer spheres.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

Learners develop an understanding of air pressure in two different activities.

In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.
