Do your pupils have the misconception that environmental predators are "bad" and harm smaller creatures? The simulation explains, in detail, the important role predators play in maintaining a stable ecosystem. Through web-based research,...

Students are focused on the big question: What makes a population grow and how could that growth stop? They use these concepts to help answer the big question: carry capacity, density dependent v. density, independent factors, predation...

Young scholars investigate the components food chains and food webs in various ecosystems. They describe how living things depend on one another for food energy (food chain) and how more than one food chain exists in an ecosystem

Middle schoolers investigate the food chain by researching the Internet.  In this ecosystem activity, students view the video "Competitor and Predator" and read a book from the series "The Magic School Bus."  Middle schoolers...

A presentation on Darwin's theory of evolution and natural selection could be a good addition to your biology class. It provides general information about how animals adapt to their surroundings, as well as how organisms create more...

Though the walrus spends roughly one third of its time on land, it eats organisms that live on the bottom of the ocean. The first in a series of five, the lesson uses a variety of plant and animal cards to have scholars build an arctic...

Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...

Providing a sweeping overview of population and community interactions, this ecology worksheet gets learners thinking. They differentiate between habitat and niche, describe and give exemplars of various animal and plant defenses,...

Chart ecological community interactions and answer questions about niche, defenses, trophic structure, and succession. This community ecology instructional activity provides a general overview of the interactions that occur among...

Students recognize that organisms depend on other organisms.  In this organism instructional activity, students understand symbiotic relationships and competition.  Students explain food chains and food webs.  Students...

Students explore wolves. For this ecology and wolves lesson, students research predator-prey relationships on the Internet and complete a related worksheet with a partner. Students interpret data on bar graphs to determine growth and...

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...

The Burmese python is on the loose ... and he's hungry! Illustrate the differences between causative and correlative relationships through an inquiry instructional activity. Pupils examine several sources of information to determine if...

How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Students research desert species to find where it lives, what it eats, and what species it interacts with directly. Upon completion of research, students construct a web of all the species as a class. This emphasizes the role each...

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.

Are spiders related to crabs? Study the order of arthropods with a reading selection about animal diversity. It provides details about each class within the order, as well as vivid pictures and explanatory charts. 

In this biology instructional activity, students explain the use of camouflage as a defense mechanism. Then they list examples of insects that use camouflage to protect them from predators. Students also identify and name other types of...

Students examine the role of large families in some animal populations. They work together to complete an activity related to food supply. They discover the relationship between preys and predators.

Students research and describe the habitat and adaptations of a reef animal. After the student is assigned a habitat, they design and draw a cresture adapted to eat each food and to live in each habitat.

In this mammals worksheet, learners research the internet to find information and answer short answer questions about mammals of fields, meadows, and hedgerows. Students complete 12 questions.

In this bird adaptations learning exercise, students look at different bird pictures and determine what the bird eats and where it lives by looking at its beak and feet. Students complete a graphic organizer and 5 short answer questions.

Students define the following terms: predation, competition, carrying capacity and population. They can explain the patterns of growth and the limitations of growth. Students explain the difference between density-dependent and...

Learners view the PowerPoint slide of a lynx and hare and discuss what would happen if all the lynxes were destroyed. They then take notes on the lesson and brainstorm about other competitive/cooperative relationships as well as discuss...
