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

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.

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.

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

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 online activity, learners discover how random variation influences biological evolution.

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

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?

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
