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
Lessons: Food Web
Learners use an interactive web-based food web game to gain familiarity with tropic levels and interactions. They already understand that in an ecosystem there are four basic tropic levels: producers, primary consumers, secondary...
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...

2005 Grade 8 Science Released Test Questions
Here is a collection of 22 multiple-choice questions on topics from the physical and life sciences. Apparently they came from an 8th grade comprehensive science exam and have been released for public use. They may serve as a sufficient...
Curated OER
Life or Death Food Chain Decision
Students discuss how energy is transferred to different trophic levels. In this biology lesson, students solve a theoretical problem and debate on a solution. They explain how energy is lost during cellular respiration.
Curated OER
Ecological Pyramids
Students apply the ecological pyramids of numbers and biomass with an activity using topographic maps. In this trophic level lesson, students work in groups using a topographic map to determine the number of organisms that can live in an...
Curated OER
Heat 1
In this heat worksheet, students determine the heat gained or lost when matter changes phases. Students review the energy flow through ecosystems by comparing trophic levels and food webs. This worksheet has 10 fill in the blank, 5 short...
Curated OER
The Biosphere
In this biosphere worksheet, students identify the different levels of organization that ecologists study. Students complete charts, sentences, and answer short answer questions.
Curated OER
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.
Curated OER
Food Webs
Students recognize interdependence in a food web by using yarn and notecards to create a food web and discussing what would happen if one of the organisms from a certain trophic level is removed.
Curated OER
Plants 'R' Us!
Students investigate the interdependencies of plants and animals, and study what a food web is. They create a food web using yarn and images.
Curated OER
Ecosystems
Young scholars 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
Principles of Ecology
In this ecology worksheet, students will fill in a graphic organizer showing the relationship organisms have with their environments and with each other. This includes biotic and abiotic factors, tropic levels, and ecological pyramids....
Curated OER
Biology Vocabulary
In this biology worksheet, students identify and locate various vocabulary terms pertaining to food webs and animal species. There are 52 biology terms located in the word search.
Curated OER
A Tale of Two Reactors
Tenth graders role-play as members of the food chain. Sticky tables acting as polluting factors are introduced and members of different trophic levels suffer varying degrees of damage due to those pollutants.
University of Michigan
University of Michigan: Global Change: The Flow of Energy: Higher Trophic Levels
This lesson addresses the following questions: What is the efficiency with which energy is converted from trophic level to trophic level? What are the differences between assimilation efficiency, net production efficiency, and ecological...
National Geographic
National Geographic: Marine Ecosystems and Biodiversity
For this unit students explore major marine ecosystems by locating them on maps. Students use marine examples to learn about energy transfer through food chains and food webs and then they discuss how food webs can illustrate the health...
National Geographic
National Geographic: Marine Ecosystems and Biodiversity
A collection of three lessons where students learn about abiotic factors in marine ecosystems, about marine food chains and biodiversity, and about marine food webs and trophic levels. Includes handouts, website links, and a vocabulary...
National Geographic
National Geographic: Marine Food Webs
For this lesson, students learn about marine food webs and pyramids, and how energy flows through a marine ecosystem. They then research a marine organism and its role in a marine food web. The class pools their information to create a...
