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

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

In this online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

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.

In this chemistry demonstration, acid rain is simulated in a petri dish.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

This is an online game about the complexities of farming. Learners will "draw" cards and make decisions about how to take care of their farm.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

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.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
