This activity lets you program your 'robot' (a willing friend) to pick up and dispose of some 'toxic waste' using as few commands as possible.

In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

In this game, learners experience how computers divide a big problem into many smaller ones and how they use binary "yes"/"no" questions.

In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

This activity is about collecting and analyzing DNA as part of a criminal investigation.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

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, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.
