Young researchers create a class Cascading Consequences chart to see the big picture of how the industrial food chain effects people, animals, and the environment. They also work in teams to complete a Stakeholders chart for the...

Using an informative resource, pupils discover how to write research questions that are focused, answerable, and relevant. Scholars evaluate resources about the industrial food chain from Michael Pollan's The Omnivore's Dilemma, and then...

Organic versus conventional farming: which option is best? Pupils use Michael Pollan's The Omnivore's Dilemma to determine the cascading consequences of the industrial organic food chain. They work in research teams to create an...

Scholars extend their research of the food chain that Michael Pollan discusses in The Omnivore's Dilemma. They determine additional consequences of the food chain and add them to their Cascading Consequences charts. Additionally, pupils...

Which of Michael Pollan's four food chains from his book The Omnivore's Dilemma would best feed everyone in the United States? Using a thought-provoking resource, scholars learn how to create a Cascading Consequences chart to answer the...

Mammals have unique interactions with their ecosystems. Using a multi-part lesson, learners research local mammals using recommended websites and use their findings to create their own paper ecosystems including appropriate mammals. They...

You are what you eat—or at least a part of what you eat. Budding scientists examine owl pellets to develop their own food webs. They use tooth and skull identification techniques to classify what they find.

Psychologists study human relationships while ecologist study relationships between organisms in the environment. An introduction to ecology and the related vocabulary benefits scholars as they progress through the presentation and...

Every living thing requires a food source, thus the interconnections in ecosystems become complex. Scholars learn about these interconnections in a presentation on energy flow. It starts with the sun and moves through many different...

As the saying goes, you are what you eat. A useful set of lesson plans encourage young readers to take a second look at their eating habits. Pre- and post-reading questions bring in reflective writing and discussion while extension...

When a minnow eats a piece of plastic, that garbage often tracks through multiple animals, causing harm to each as it passes through the food chain. Scholars learn about food chains, food webs, and energy pyramids with a presentation. It...

It's a jungle out there! Young biologists journey to Darien, Panama to examine the intricate relationships between the organisms that inhabit the jungle. Groups begin by demonstrating an understanding of energy flow in ecosystems, then...

Thirteen short-answer questions follow a brief food web activity in a formative assessment designed to test knowledge of ecosystems and the energy that flows through them.

Tooth be told, your class is gonna love this video! Science scholars look beyond simple cell types and enter the world of teeth. The narrator describes how we think teeth evolved to their present form, how form dictates function, and how...

Learn more about food chains, the food web, and the concepts relating to them. It focuses on consumers, producers, decomposers, energy transfer, and energy loss across trophic levels.

Cats and dogs throw up after eating grass because their digestive system isn't built to process these fibrous proteins. The activity allows pupils to explore animal feeding habits. Scholars discuss and define carnivores, omnivores, and...

In spring, the Bering Sea turns green due to phytoplankton, which live at the surface, experiencing a population explosion. Groups of scholars play a food chain game, writing down food chains as the game is played. After five to six...

How does one organism get its energy? What is the main source of energy in an ecosystem? How does the flow of energy affect different types of ecosystems? Answer these questions with a fill-in-the-blank worksheet. 

How do different types of living things get the energy they need? This is the focus of a video that describes how carnivores, herbivores, and omnivores get the energy they need to live.
