Second in a pair of activities, young ecologists continue to examine the food pyramid of a freshwater ecosystem. They take a look at the food pyramid drawn in Activity A and consider what would happen if a reservoir was created on the...

Students explore biology by creating a report for the class. In this oceanography lesson, students research and identify the survival characteristics of a list of freshwater animals by utilizing the Internet and library. Students...

Written for Washington state students in life science, this lesson provides an opportunity to examine the residents of local freshwater habitats. You or the class collects a water sample, and learners try to examine what organisms live...

How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...

At this site from the Missouri Botanical Garden, you can learn about the wide variety of plant and animal life in or around fresh water ecosystems. Click on the links to "wetlands," "Ponds and Lakes," or "Rivers and Streams" to view...

An activity where students create a mobile that represent a freshwater ecosystem that appears in nature. Requires Adobe Reader [PDF].

In this activity, students' use a pH sensor and Temperature Sensor to measure and compare the pH and temperature of three aquariums over a period of several weeks. They will compare and understand how plants and animals affect the water...

By looking at the bottom dwelling macroinvertebrates, students will investigate water quality and habitat quality in this field lab. Students will record the number of creatures found at the bottom of a pond, lake, ditch, stream or river...

[Free Registration/Login Required] The abcteach directory contains sample pages from their pond unit for non-members. Handouts are in PDF format.

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.

Use this site to see how many of the animals and plants that your students can remember from each biome after listening to this song.

Doug Eldon performs this great song which tells about the different biomes and their characteristics. Great way to begin your unit on the biomes.
