This site explains how to use evidence from fossils to understand the ecology of ancient organisms. Fossils provide clues and together abiotic and biotic factors combine to form complete ecosystems, each with its own unique ecology and history. Predator and prey relationships and dispersal are used as examples to show how fossils can also tell us about biotic factors, such as what organisms are present ... Full description.

This article discusses the different zones of light that exist within the ocean and how the varying degrees of sunlight and total darkness affect what lives in each zone. Specifically, it covers: the photic zone, the only region where plants and organisms that depend on photosynthesis can live; the aphotic zone, where light is too dim for photosynthesis and organisms rely on detritus (bits of decaying ...

This experiment will help students to understand the role of plants in filtering the water moving through a watershed. Students will discover that soil and plants have something of a dual role in this process and, depending on whether materials are dissolved or suspended in the water, soils and plant roots can remove some or all of this material as the water moves down through soil. They also learn ... Full description.

Using this material, students will discover that under special experimental conditions, fish have been observed functioning in ice-free cold salt water at a temperature of -6 degrees Centigrade. Research has found that these fish have eight types of anti-freeze molecules which bathe the interior surface of their skin, acting as a barrier to ice propagating in from outside. When the anti-freeze molecules ... Full description.

In this lesson students will access a link to another site to learn about the processes that drive geysers, which are roughly analogous to hydrothermal vents. They will then examine photographs of some hydrothermal vents, discuss the reasons they occur, and learn about some uniquely adapted animals that live near the vents. They will conclude by creating aquarium exhibits showcasing some of these ... Full description.
