As part of a study of food chains and food webs, class members complete a series of worksheets that trace a marine chain from producers to consumers or decomposers. After studying a food chain example, young marine biologists make up...

Students explain the main concepts of food webs and food chains. They describe the role of animals, plants, and other organisms in cycling energy and matter through a food web by creating mobiles. Lesson contains adaptations for all levels.

Learners explore food chains. For this ecosystem lesson, students discover how plants and animals rely on each other for survival. Learners research the rocky shore ecosystem and create a skit representing the ecosystem.

Learners create a bulletin board display illustrating food chains they make from a list of ocean organisms. Students also play a game showing what happens when one of the organisms is removed from the food chain and how they are all...

Using a magnifier, mini marine biologists examine the barbules of a bird feather. They swirl the it into a mixture of oil and water and then re-examine the feather. After the activity, discuss how the oily feathers pose a problem to...

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...

Students explore the food chains in a variety of ecosystems and its relationship to the survival of threatened or endangered marine animals or fish in the ocean. The interdependence of the species is investigated in this lesson.

Students understand the importance of each member of a food chain through a game.  In this food chains instructional activity, students receive background information and then play a game to simulate what happens in the food chain...

For as small as they are, plankton sure play an enormous role in maintaining marine ecosystems. Dive into an investigation of these tiny organisms with a hands-on life science activity in which children cut out pictures of sea...

In this food web crossword puzzle instructional activity, students use the 23 clues to identify the correct terms that will solve the crossword puzzle.

Young scientists discover how sea otters' habitats have changed due to human impact. Through conversation, video observation, and story reading, scholars identify how human interactions change a specific ecosystem in both positive and...

Producers, herbivores, carnivores, omnivores, decomposers. To begin a study of the forest ecosystem, learners examine the connections among the members of ecological communities.

Students look at the data maps given to them about how chlorophyll affects the algae blooms and make predictions about the harm they will cause. In this data maps lesson plan, students manipulate data sets from the website.

In this ecosystem worksheet, students use a diagram of an ocean-based food web to complete 5 short answer questions about the energy flow through this ecosystem.

Krill is a very small ocean animal that is key to keeping the ocean ecosystem going. The class reviews food webs and chains, learns about the importance of krill, discusses krill anatomy, builds a model of a krill, and then has a...

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

Students, after locating different marine habitats on a globe, play a card game about ecosystems, food webs and organisms.

Young scholars explore biology by creating a report for the class. In this oceanography lesson, students research and identify the survival characteristics of a list of freshwater animals by utilizing the Internet and library. Young...

Students identify and discuss the adaptive characteristics and behaviors of fish. They view slides of fish, and design and create a model of a fish of the future, listing the ways their fish adapt to survive.

Read about the different predators, consumers, and producers that make up an ocean food chain.

Describes five different types of decomposers that feed on decaying organic matter in the oceans and that are at the bottom of the ocean food chain.
