In this environment instructional activity, students read a passage on why alien species should be introduced to ecosystems. Then they respond to four questions that refer to the passage read. Students also respond to two decision...

Students study a local ecosystem and research the organisms to create a food web. In this ecosystem lesson, students view a video and answer questions. They visit a local ecosystem and make a list of organisms to research. Students...

Seventh graders research organisms in the Merritt Island National Wildlife Refuge. They create a picture book demonstrating their understanding of relationships.

Students, working independently and in groups, apply the distance formula to practical situations. After solving various problems, students in pairs design coordinate planes from the school blue print to measure the distance from the...

Students observe elements of a local ecosystem and gain an understanding of what elements make up an ecosystem.  In this ecosystem lesson students create a class food web that shows the interactions among the elements of the...

For this living things worksheet, learners review terms and concepts about the different relationships between living things. This worksheet has 7 true or false and 5 short answer questions.

Students develop an understanding of the different fields of study that are encompassed by the term, life science. They view and discuss a video on the topic. In small groups they focus on on of the examples shown in the video to create...

Students examine the different plants and animals in British Columbia.  For this forest ecology lesson students explore how ecosystems work, classify animals and investigate food webs and chains. 

Students investigate ecological systems and the multiple uses of the environment by studying the osprey population.

Explains what a predator-prey relationship is and describes ten examples of this.

You can download a database made by Dr. Robert LaVinge. The database will give you almost every predator prey relationship.

[Free Registration/Login may be required to access all resource tools.] Discover the predator prey relationship and the ways organisms adapt to predation. Understand the impact predation has on population size and evolution.

Understand the predator-prey relationship in an ecosystem.

A comprehensive resource on the topic of predators. Includes half-hour video, facts, links, a reading list, resources for teachers, and a glossary, While there are links to videos, they may no longer work.

This activity helps students understand how predator-prey interactions affect population sizes and how competitive interactions affect population sizes. They will also explore the major factors that influence the predator-prey relationship.

Students are asked to explain the predator/prey relationship and how it helps to maintain the balance of the ecosystems.

Examine the predator/prey relationship between wolves and moose in Alaska's Denali National Park and discuss how the balance of nature works between these two animals.

Explains what a symbiotic relationship is, the five main types of symbiosis, and provides examples of symbiotic relationships among living things in a deciduous forest.

Students control the environments in four different scenarios to discover how any changes might affect populations. The different simulations include microorganisms, rabbits, foxes, and other organisms.

In this problem about the predator-prey relationship between the fox and rabbit populations, 8th graders are asked to identify and explain any functions that they see. Aligns with 8.F.A.1.

In this lesson, students 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 levels of order...

You can download a database made by Dr. Robert LaVinge. The database will give you almost every predator prey relationship.

Species interact every day. That interaction is a vital part of how organisms develop and change over time. When you study species, it is important to watch the way they interact with their surroundings. There are four basic types of...

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...
