In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this online Flash game, learners will captain a sailing challenge, adjusting boat direction and sails, seeking the way to take greatest advantage of varying wind speeds and directions to catch the

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.

In this online Flash game, learners test their engineering know-how, moving a collection of mechanical parts onto a board to make complete a system of parts that will move a ball from start to finish.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

In this activity, learners use sieves with different-sized holes to sort balls by size.

In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

This activity is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Learners look through two cups with small holes in them to simulate what it'

This is an online Flash game where learners can experiment with ballistics and how to compensate for the varying levels of gravity found on the planets of our Solar System.

In this online Flash game and spacewalk mission simulation, learners are challenged to repair parts of a space station while balancing their oxygen and fuel use carefully.

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

This game plays a dozen different sounds, altered to simulate what they would sound like if you had hearing loss.
