Modeling Trophic Cascades
In the ecological game of who eats who, one small change can have a big impact! Individuals create food chains in an array of ecosystems, then determine what happens to organisms in the chain when one organism changes its feeding...

Forest Ecosystem
Students become familiar with the temperate rainforest. In this forest ecosystem lesson, students identify the producers, consumers and decomposers in the forest ecosystem. Students sort cards and identify the trophic level of the...

The Interdependence of Birds and the Great Salt Lake Ecosystem
Tenth graders participate in the "Checks and Balances" game. This game lets them experience the interdependence of oragnisms specific to the Great Salt Lake. They recieved informaton about food chains, food webs, trophic levels various...
Curated OER
Trophic Pyramids and Levels
The bulk of this lesson involves the construction of both an aquatic and a terrestrial ecosystem in which to observe trophic relationships. Detailed directions are provided, as well as discussion questions, and assessment activities....
Curated OER
Aquatic Ecosystem Exploration
Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...
Curated OER
Ecosystems
A critical look into the structure and function of ecosystems is here for young learners as a series of lessons and worksheet activities. Topics covered include land-based and marine ecosystems, connections to the water cycle, food webs,...
Curated OER
Trophic Ecology of Humans
students analyze the place of humans among the tropic levels by observing what we eat. They calculate the caloric content of several foods commonly eaten by humans and calculate the total energy cost to grow, process, transport, store...

Deep-Sea Ecosystems – Entering the Twilight Zone
Imagine an ecosystem without any light or oxygen, where living things convert carbon dioxide into food. This ecosystem is thriving and might just be the largest ecosystem on our planet, yet we know very little about it. The instructional...
MENSA Education & Research Foundation
Ecosystems
Explore the Earth's different ecosystems through four lessons, an assessment, and extension activities. Lessons include informative text and step-by-step instructions to apply knowledge in interactive, and thought provoking ways; such as...

Food Webs, Energy Flow, Carbon Cycle, and Trophic Pyramids
The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...

Energy Flow in Ecosystems
Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...
Biology Junction
Energy Flow in an Ecosystem
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...

How Does Energy Cycle in Ecosystems?
In this energy cycle worksheet, students will write in examples for each trophic level in an energy cycle: top, middle, and lowest levels.

Lesson 4: Gorongosa's Food Webs
Who eats who in the savannas of Africa? Explore trophic levels with part four of an eight-part series of lessons focused around Gorongosa National Park. After young explorers identify animals using trailcam images, they construct a food...

Construction of Food Chains and Tracing Energy Changes
If you need a few basic activities for teaching food chains to your emerging ecologists, here they are. Three sheets of organism cards are included for learners to cut out and arrange according to trophic relationships. To make the most...
Scholastic
Study Jams! Food Webs
Rhinozilla is back to take your lesson plan on trophic levels a step higher! After showing the video on food chains (available through the See All Related Jams button), add to it by showing this one. It deals with omnivores and food...
Curated OER
Ecosystems
Students work in small groups to create a poster illustrating the flow of energy through a typical ecosystem, then present their posters to the class.
Curated OER
Trophic Ecology of Humans
Students analyze the trophic level of humans by first calculating the kilocalories in own their lunch. They then calulate the kilocalories in a wide variety of foods found in grocery stores and compare the kilocalories needed to acquire...
Curated OER
Food Webs and Making Miniature Ecosystems
Students model a food web and create a miniature ecosystem. In this animal interactions lesson, students engage in a role playing game which simulates a food web. Students then build miniature ecosystems using pop bottles, snails, plants...
