For as small as they are, plankton sure play an enormous role in maintaining marine ecosystems. Dive into an investigation of these tiny organisms with a hands-on life science activity in which children cut out pictures of sea...

In the ecological game of who eats who, one small change can have a big impact! Individuals create food chains in an array of ecosystems, then determine what happens to organisms in the chain when one organism changes its feeding...

Packed with visual aids and multiple learning opportunities, an engaging exercise challenges individuals as they explore the role of producers, consumers, and decomposers. After discussing differences between food chains, food...

We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment...

Chemicals from the Earth's atmosphere are making their way down to the planet. Not in spaceships, but in rain. The acid rain can infiltrate ground water, lakes, and streams. How does acid rain affect aquatic ecosystems?

In this science fair project you will learn about biomes and how different climatic conditions affect plant growth. This can explain why some plants and animals are similar in different areas of the country, and in other parts they are not.

Did you know that when you use fertilizer in your garden, it can eventually reach a lake, stream, or pond? There are many different chemicals present in fertilizers. Learn how they affect the aquatic organisms in the ecosystem within...

A lab experiment, in a series of experiments, that investigates fisheries. In this lab, students test the effects of fertilizers and other pollutants on a model ecosystem. Students also examine 2 years of ocean color (chlorophyll...
