Young scholars explore the interconnectedness of living things in an ecosystem. They use pictures and arrows to develop a food web, and participate in constructing a class food web with students representing various parts of the web.

Three activities introduce upper elementary ecologists to photosynthesis and food webs. In the first, an experiment is set up to determine how plants respond to different types of light. In the second, they connect organism cards with...

What happens when a non-native species is introduced onto an island? Santa Cruz Island, part of the Channel Island chain located off the coast of southern California, provides the perfect laboratory for young environmental scientists to...

Young scholars gain knowledge of food webs and ecological interconnections in the forest, and place different life forms in their proper place in a food chain. Students appreciate the balance of nature and how humans are affected by...

Students investigate how food chains work. In this food chains instructional activity, students construct a food web for a pear tree habitat. The interactive whiteboard is an optional tool in this instructional activity.

Pupils 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 instructional...

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...

Young scholars examine the concepts of ecosystems and interdependence. They construct block pyramids to demonstrate interdependence, and map off an area to observe and identify animals. They create food chain mobiles and play a web of...

Students describe vertebrates in terms of observable body parts and characteristics and describe life cycles of familiar organisms. They identify familiar organisms as part of a food chain or food web and describe their feeding...

Students explore organisms that are part of interconnected food webs.  In this food web lesson, students choose an animal and research what the animal eats.  Students begin with the food chain and branch out into the...

In this ecosystem worksheet, students answer questions about energy pyramids, food chains, consumers, producers, decomposers, biotic and abiotic factors in an environment, natural selection and the importance of biodiversity in an...

Sixth graders investigate the role of owls in their ecosystem. In this food chain lesson, 6th graders illustrate an owl food chain, dissect an owl pellet, and analyze data. Students discuss what would happen to owls if there were an...

Students explore the dangers of eating high levels of mercury and how small amounts of mercury in water accumulate in greater quantities in organisms higher in the food chain. They list the health of effects of high levels of mercury on...

While this lesson plan focuses on the birds and fish found on the Hudson River, it could be adapted for use in any classroom. Using a vocabulary list, learners explore the meaning of words like adaptation, habitat, barbel, and more....

In this chemistry worksheet, learners watch a movie about food chains and use it to respond to each of the questions stated. They use the list of works in the word banks to assist them in matching the correct term to its description.

Students identify producers and consumers, including scavengers and decomposers, and discuss role each plays in food web. They then make diagram of possible food chain that might include skull pictured on Montana's quarter, and...

Students identify the different organisms in the food web. In this biology lesson plan, students create food chains using the information on cards. They explain what happens if an organism is removed or added in the web.

Young scholars explore food chains and food webs in a pond and identify common creatures found in ponds. They look for tadpoles, fish, mites and other creatures in a pond during a field trip for first hand research.

In this ecoregions of Texas worksheet, students complete a summary of a particular ecoregion in Texas. They find the producers and consumers of the region, they draw a food chain, the draw a food web, and they complete an energy pyramid...

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...

In this food web worksheet, students will write down the 4 steps energy takes as it flows through a food chain. This worksheet is a graphic organizer.

A food web has no organism higher than a tertiary consumer because there wouldn't be enough energy left to sustain them. The fourth installment in a seven-part series begins with a nature walk to get pupils thinking about their...

Budding scientists work collaboratively to reenact energy flow in a food chain. Scholars take on roles such as producer and consumer and perform tasks that symbolize energy flow in order to provide evidence of how much energy passes...

Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...
