Ecosystem Ecology: Links in the Chain

A small little ant can have a large impact on its ecosystem. Young researchers explore the different species that live in a plains ecosystem. They find the characteristics of several species and then compare species to determine how...

Young scientists explore the interdependence of organisms with this simple life science activity. Using the provided template, students create and label tiered pyramids that model the hierarchy of trophic levels in ecosystems.

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

What a web we weave. Pupils use yarn as the primary resource to create a web depicting the intricacies of a salt marsh ecosystem. They participate in a question and answer session, which leads to an in-depth facilitated discussion about...

Can an area with no soil turn into a forest? Scholars learn about the process of ecological succession using an interesting presentation. It covers both primary and secondary succession in the building of new ecosystems.

Examine the evolution of various species of hominids from their earliest existence approximately 4.5 million years ago to today. In small groups, learners research one of the ten stages of hominid evolution and then create a poster and...

A disgusting and direct description of detritus and decomposition is digested in this drill! Your life science class learns about the importance of decomposers in the food chain and finds out how one organism's trash is another...

The interactions among the members of an ecosystem are what keeps all organisms living together successfully. Using an informative PowerPoint, individuals learn about how energy cycles through ecosystems in food chains and food webs....

With the world's largest collection of geysers, many visitors end up overlooking the wildlife natural to Yellowstone National Park. Join Mr. Andersen as he shows your class about the different species living in the park and illustrates...

The coral reef ecosystem is abundant and lively. Dive in for an underwater view of the species living there. Polyps, urchin, barracudas, and eels (among others) exist in part because of the sun's presence in this ecosystem. Use this as...
