Explore living in an alkaline environment with this three-part interactive activity. During these activity students will complete web quests and activities to investigate the ecology and diversity of life in this environments.

An illustrated article which provides a overview of ecology including several important interactions affecting ecosystems.

This comprehensive Grade 7 Science unit has three chapters on forest ecosystems, natural cycles in a forest, and human interactions with a forest. Each chapter has experiments, activities and questions complete with answers. There are...

In the environment, there are external factors that really affect organisms living within it. One of these factors is the set of abiotic factors, or nonliving variables, such as wind, ocean, day length, rainfall, temperature, and ocean...

A lab experiment in a series of experiments that looks at fisheries. In this particular lab, students use tools like Pacific Ocean Shelf Tracking to learn about the management of fisheries through an ecosystem-based approach. During this...

Interspecific competition in an ecosystem is explained, along with the different ways it can manifest itself. Includes examples in different types of biomes.

In this instructional activity, learners compare various types of relationships among organisms (i.e., biotic interactions). Students will: explain the roles of producers and consumers, and predators and prey in an ecosystem. Explain the...

[Free Registration/Login may be required to access all resource tools.] Videos, texts, activities, and assessments about food chains and food webs in an ecosystem.

Students explore the effects that ecosystem disruptions can have on animal populations. They learn about the disruptions that have driven three species-the Madagascar fish eagle, the Iberian lynx, and the rowi kiwi, to the brink of...

This activity is designed to accompany an interactive on the Annenberg Learner website. Students investigate the changes that take place in an ecosystem when they alter the organisms in a food web. As they work with the simulation, they...

An activity for students to document biodiversity and observe ecological interactions in their own backyard.

Answer these ten interactive questions about ecological feeding relationships by choosing the correct image that completes each food chain.

Create the parameters of your own ecosystem by choosing which producers and consumers live there. Visualize how the food web operates and species populations change. This simulator mimics the food web within a typical ecosystem and gives...

[Free Registration/Login may be required to access all resource tools.] Ecology is the study of ecosystems. That is, ecology is the study of how living organisms interact with each other and with the nonliving part of their environment....

An ecosystem is composed of biotic factors of a community of living organisms interacting with one another which we can see in food chains/webs. These diverse organisms stay together because of the need of food. Population is referred to...

Fun, interactive game that helps students identify interrelationships in an ecosystem. For six or more players.

Describes the role of mutualism in an ecosystem and the different types, and provides examples.

Students learn about the feeding relationships in an estuary ecosystem with this interactive energy pyramid activity. A second activity involves research and a video clip to elaborate the learning.

A field experience where students undergo an exploration in a natural environment. They are introduced to the concepts of species, population, community, ecosystem, niche, and biosphere.

This resource presents information about wetland ecosystems and the importance of habitat conservation in this resource and then try an interactive activity to identify tracks of wetland animals.

[Free Registration/Login may be required to access all resource tools.] Predation is another mechanism in which species interact with each other. Predation is when a predator organism feeds on another living organism or organisms, known...
