Students study ponds and wetland ecosystems and examine the food chains and webs in them.  In this aquatic ecosystems lesson students answer questions about the diversity of the flora and fauna in a pond. 

Ninth graders describe the six levels of ecological organizations and give examples of each. They also differentiate between food chains and webs and identify trophic and consumer levels in food chain and food webs.

The Arctic food web may be more limited than other environments, but it has all the same components. With an interactive activity, pupils assume the roles of the components of an Arctic food chain. They move around and link themselves to...

Three types of symbiosis are explained: parasitism, commensalism, and mutualism. This is done with colorful animation and lively dialogue in a straightforward and easy-to-follow manner. Have your ecology class watch this at home and then...

In this early childhood science worksheet set, students study the importance of water, and determine the difference between themselves and water dwellers. They look at adaptations, river life, rainforest life, food chains, pollution, and...

Students investigate the decomposition process. In this ecology lesson, students participate in a play, "Up the Treehouse" where the main idea focuses on a decomposing tree and how food chains are effected by decomposition. After the...

Students describe the importance of having a balance ecosystem. After a brief lecture, students give an explanation of the properties of an ecosystem. They create a web, using yarn which shows how the various members of the ecosystem are...

Students research phytoplankton and zooplankton. For this food chain lesson, students read This is the Sea That Feeds Us and discuss plankton, food chains, and webs. Students define phytoplankton and compare them to land...

Students study the benefits of estuaries. They construct a saltwater food web, and complete worksheets and a quiz.

Students participate in a web of life game. After reviewing new vocabulary, they play each round of the game and discuss the changes that occured in the last round. They are to survive in the game as long as possible given the...

Ninth graders discuss the principal source of energy entering the marine ecosystem. They name some of the autotrophs at the Maui Ocean Center. Students name some of the heterotrophs at Maui Ocean Center. They are taught that plants are...

Get your hands dirty with an interactive instructional activity that showcases the process of decomposing and returning nutrients back into the soil. After building a compost pile, pupils regularly observe the...

Students will be able to find out about feeding relationships on a coral reef. They then will be able to develop a food chain and food web using coral reef animals and plants using the Coral Website.

Students explore the basics of ecology through numerous hands-on and relevant activities. They participate in an online food chain demonstration, which explores food web dynamics. They dissect owl pellets, examine the prey's bones, and...

In this science learning exercise, students match the words given in the first column with the correct definition found in the second column. There are six vocabulary terms to define.

Students are given an introduction to the "ecosystem", what factors make up an ecosystem (biotic factors, abiotic factors, food chain, producers, consumers and decomposers) and how those factors interact.

Students explore the coast lines of Florida. They examine the benefits of estuaries and examine the estuary systems found along the coast. Students research and construct a saltwater food web.

Young scholars simulate online the formation of Ape Cave, in order to better explain its construction. They observe, illustrate and discuss geological features of this lava tube.

Students explore key terms, including food web and food chain. They discuss Arctic plants and animals, devise at least three Arctic food chains and create a food web showing connections among Arctic life.

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

Fourth graders examine the megafauna found in Australia. They create a food web using cut-outs and develop a timeline to show changes in the fauna over time. They draw their own megafauna scene for their classroom.

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...

Second graders compare and contrast animate and inanimate objects. For this environmental science lesson, 2nd graders create simple food webs. They observe their environment and create a collage about it.

In this ecology worksheet, students will review 10 vocabulary words associated with the basic principles of ecology. This worksheet has 10 fill in the blank questions.
