Using PING to determine factors of Internet delay

What does the ground around your home have to do with water pollution? Young ecologists learn about their local watershed and create their own cause-and-effect models of the hydrosphere.

Young mathematicians put their skills to the test in the real world during this four-lesson consumer math unit. Whether they are learning how compound interest can make them millionaires, calculating the cost of remodeling their bedroom,...

Historians have proven that as early as 1497 skilled navigators were using a kamal to sail across oceans. Scholars learn about navigation tools and astronomy before building their own kamals. They then learn how to use it to determine...

Let's go fly a kite. By flying a kite, class members observe the difference in air flow. The class notices the characteristics of banners tied to the kite string to determine where wind turbulence stops. Adding an anemometer to measure...

Determining whether or not something is living can be more difficult than it seems. Put your young scientists to work defining their own criteria to identify life, then work with three samples to see if they are alive or not.
