Populations and Ecosystems

Introduce ecology classes to biodiversity and interdependence in ecosystems with a PowerPoint presentation. Then, they get up-close and personal with the invertebrate world by collecting insects, classifying them, and graphing their...

How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases and...

An environmenta science unit includes three lessons plus a cumulative project covering the ecosystem. Scholars follow the history of the Ford Rouge Factory from its construction on wetlands and how it destroyed the environment to its...

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 animals...

Find your niche in the science classroom. Learners study the role of niche populations within an ecosystem and consider the impact of the loss of these organisms. Their investigation includes vultures, honey bees, and mosquitoes.

Young biologists trace the path of the sun's energy through marine ecosystems in the second part of this four-activity series. Building on prior knowledge about producers, consumers, and decomposers students are introduced to the concept...

Learn the implications of extreme climate changes on ecosystems. Young earth scientists explore the desertification of areas in West Africa and consider implemented solutions. Their study includes analysis of climate data from the area...

Jump into an exploration of marine ecosystems with the first lesson in this four-part series. After first learning about crustaceans, mollusks, and other forms of sea life, young marine biologists view a PowerPoint presentation that...

From tiny organisms to entire biomes, young scientists examine the interdependent relationships tying all living and non-living things together with this collection of ecology resources.

After a discussion on food chains and what animals eat in order to survive, groups of students take a closer look at organisms and their roles in earth's ecosystems. Next, pupils choose an animal in which they develop a food chain rough...
