Students 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

Young scholars explore the why the balance among producers, predators and prey is necessary in order for an ecosystem to be sustained over time. Through web games and activities, they discover how each component of the food chain works...

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

Students explain how the food chain works. They contrast predators with prey and describe their function in nature. Students discuss how the food chain aids in keeping nature balanced. In small groups, they play a game that simulates the...

Too many predators or too many prey is not good for a habitat. Pupils learn how the predator-prey relationship serves to maintain healthy populations with a game simulation. Individuals take on the roles of either a predator or prey and...

Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

For this balance of nature worksheet, students use a data chart to graph wolf and deer populations over a ten-year period. Students use this graph to complete 3 short answer questions.

Students explore how predators help control the growth of prey species for a more balanced ecosystem.

Young scholars 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. Young...

Students explain how the food chain works. They contrast predators with prey and describe their function in nature. Students discuss how the food chain aids in keeping nature balanced. They play a game that simulates the food chain.

Middle schoolers build a video game on predator-prey relationship. For this biology lesson, students identify the variables that affect this relationship. They write a short description and play each other's game. 

Students identify the role predators/prey play in food chains, differentiate between food chains and webs, identify factors that affect the balance in food webs, and propose solutions to protect endangered species' environments and...

Students study and analyze data collected on the relationship between the snowshoe hare and lynx in Canada over a 28 year period and create a graph. Students also write a response to a proposal to reduce the lynx population.

Students explore the marine ecosystem and the importance of sharks. In this shark lesson, students look at photos of the Flower Garden Banks National Marine Sanctuary and discuss the animals that live there. They discuss which animals...

High schoolers investigate defensive mechanisms of insects and organisms.  In this biology lesson plan, students draw imaginary caterpillars as well as imaginary parasites that will harm the caterpillar.  High schoolers utilize...

In this environment worksheet, 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 questions by giving...

Fine dining can happen anywhere, even in the coral reefs. Budding environmentalists explore marine food chains, predator-prey relationships and the importance of a balanced ecosystem. These important concepts are facilitated through a...

Third graders investigate the balance of ecosystems and how each species has different survival needs. They research on the internet using the site included. They then participate in activities/centers utilizing the facts they discovered.

For this amphibians worksheet, students click on the links in the questions about amphibians to find the answers to the questions and then come back and answer the questions. Students answer 10 questions total.

Students create a WANTED poster about an invasive species to an ecosystem. In this invasive species lesson plan, students watch a video and research an invasive species and create the WANTED poster about it.

Learners complete a worksheet while viewing a film about sharks. They examine the reasons for overfishing of the oceans. They identify predator-prey relationships as well.

Seventh graders complete a virtual online salt marsh tour. In groups, they observe and identify the various types of animals found in the marsh. After categorizing the animals, they create a food web based on the animals role in the...

Students explore oceanography by researching the great barracuda.  In this animal life lesson, students read several vocabulary terms dealing with ocean life and examine a drawing of a barracuda.  Students examine the many...

Students uses this game to see how difficult survival is even for a fierce predator, especially when it is young. It stresses: How much energy it takes to keep a large animal alive or a small one growing, The differences in the fauna...
