The Algae-in-a-Bottle Experiment provides an engaging and flexible high-impact teaching tool for helping students to know, understand, and apply a number of concepts related to the biology and ecology of aquatic plants and their environments.

This lesson aims to teach students the difference between food webs and food chains, as well as how toxins in our environment affect large predators through biomagnification. 

This article describes some common misconceptions that elementary students may have about biomes and ecosystems. It also includes suggestions for formative assessment and teaching for conceptual change.

This is an online learning experience that transports learners around the world to different locations related to the Cretaceous -- Paleogene (K -- Pg) extinction event. Students will collect and analyze evidence to explain how natural events impact life on Earth.
The KPg extinction event, which occurred 66 mya, caused the mass extinction of nearly 75% of the plant and animal species on Earth, including the dinosaurs. It is marked by a thin layer of sediment which can be found throughout the world in marine and terrestrial rocks.

Ecology For All! Is an ecology text designed in modules so that instructors can choose the pieces that make sense to assign in their context. This book has been in development for several years and is a collaborative effort of authors at Gettysburg College, Franklin & Marshall College, and University of Pittsburgh. The textbook covers a wide range of topics including Introduction to Ecology, Evolution, Adaptations to the Physical Environment, various ecological communities, Population Ecology, Behavioral Ecology, Species Interactions, Ecological Succession, Biogeochemical Cycles, Landscape Ecology, Biodiversity, Conservation Biology, and Human Impact on Global Climate among others. The authors have presented on it at the Ecological Society of America meeting and the book continues to evolve.

Students synthesize their understanding of energy flow and trophic relationships through “Food Chains Rummy,” a modified version of the classic card game using Species Cards.

This video segment, adapted from NOVA, describes the energy flow in a coral reef, including its food web.

This 4-H project book includes a series of eight activities, focused on polar science, that youth can complete with an parent or mentor. Each activity includes a hands-on component and options for communication. The activities featured are appropriate for use outside of 4-H, for instance in science classrooms, with after school programs, or during enrichment camps. Each activity includes links to supplemental materials to extend learning.

In these life science activities, students will participate in field observations of living things & do research of animals they observe to create a food chain & present it to the class. Students will participate in a food web simulation game.

By using this tiered assignment students at different levels are able to review characteristics of living things by either creating a food web or food chart.

Students will observe organisms in their ecosystem and describe the flow of energy in food webs

This article highlights hands-on or multimedia lesson plans about the tundra and ecosystem concepts. Science lessons are paired with suggested literacy lesson plans. All lessons are aligned to national standards.

From the driest deserts to the lushest forests, ecosystems are networks of life where organisms and the environment interact. In this episode of Crash Course Botany, we’ll explore how plants function as the foundations of these systems, without which no other life on Earth would be possible.

Chapters:
The Foundations of Ecosystems
Autotrophs
Heterotrophs
Food Webs
Protecting Wild Tomatoes
Keystone Species

Students practice building food chains and webs, explore interrelationships in the EOL Food Webs Tool, then model the flow of energy in food webs.

Students model how a complex system operates and how some parts of a complex system have more leverage or influence on the rest of the system. Students relate this to the interconnectedness of food webs.

This activity is a field investigation in which students identify organisms and their energy sources. Students collect data and create a food web that explains how the organisms in their ecosystem are related.

This activity is a field investigation where students list plants and animals they observe. Students will organize their data as producers, consumers, or decomposers and create a food web showing how they affect each other. They will predict what will happen if the food web becomes imbalanced by extinction or over population.

This course provides an introduction to the study of environmental phenomena that exhibit both organized structure and wide variability—i.e., complexity. Through focused study of a variety of physical, biological, and chemical problems in conjunction with theoretical models, we learn a series of lessons with wide applicability to understanding the structure and organization of the natural world. Students also learn how to construct minimal mathematical, physical, and computational models that provide informative answers to precise questions.
This course is appropriate for advanced undergraduates. Beginning graduate students are encouraged to register for 12.586 (graduate version of 12.086). Students taking the graduate version complete different assignments.
