How Many Animals?
Students use their math skills to develop estimates for the population of several animal species native to the Austrailian rainforest. It is a simulation that researchers at the Center for Rainforest Studies in Australia perform to...
Curated OER
Micro-Ecosystems
Students create a sustainable, self-contained ecosystem in a ten-gallon aquarium.
Curated OER
Organisms and Their Environment
Young scholars explore Earth's biosphere. For this biosphere lesson, students participate in group activities regarding biotic and abiotic factors, population density, and species' habitats.

"Croak" Science Mystery
Solve the mystery of a declining frog population! Lead your junior ecologists on an investigation that simulates actual events concerning pollution, predation, poaching, and more. Investigators read a story online, then analyze survey...

Visualizing Vocabulary in an Ecosystem
Sixth graders observe the pond ecosystem. In this ecosystem lesson plan, 6th graders observe the organisms at the pond and create a poster that illustrates the pond.
Curated OER
Communities and Biomes
In this communities worksheet, students will look at the interactions between biotic and abiotic factors and the effect these factors have on organism populations. Students will also order the succession steps that occur over time in an...
Curated OER
Ecosystem Interactions Web
Students pick an ecosystem (forest, desert, coral reef, open ocean, grassland, mountain, savanna, etc.) and design an interaction web for their chosen ecosystem. Each group shares their ecosystem's web of life with the class.
Curated OER
Population Dynamics
Students discover how organisms are dependent on one another for survivial. They also discuss how to conserve natural resources. They compare and contrast the different types of symbiotic relationships as well.
Curated OER
Making Connections, Linking Population and the Environment
Students find out that all habitats have a carrying capacity. They explore how the world's human population has grown markedly in the 20th century, and that humans impact environmental health. Students investigate that people can and...
Curated OER
Ecosystems
With a variety of multiple choice and short answer questions, the handout found here could be used in many ways in the classroom: pretest/posttest, study guide, reading guide, or entry/exit questions. There is not a lot of space for...

Identifying trophic levels and the skeletal system through Owl Pellets
Students identify a food chain sequence. They compare, identify, and record the rodent skeletal parts to a rodent skeletal diagram. Students construct a rodent skeleton from the skeletal parts found in the pellet. They are given the...

Computer Simulation of the Sonoran Desert Community
See how changes in initial populations and parameters affect a biological community. Individuals use a special software program to simulate a desert community with five species. They adjust initial populations to see how the community...

Niche Partitioning Activity
Dinnertime on the African savanna is a highly choreographed event! Introduce young ecologists to the concept of niche partitioning through a hands-on activity. Pupils research animal behaviors and use data to develop an understanding of...
ARKive
Temperate Rainforest in the Pacific Northwest
Explore the amazing temperate rainforest of the Pacific Northwest. Your class starts by investigating the animals and plants of the Northwest, specifically Washington, and then research an animal population common to the area. In small...

Measuring Biodiversity in Gorongosa
Take your biology class' understanding of biodiversity to a whole new level! Ecology scholars use data to calculate three different diversity indices based on the organisms in the Gorongosa National Park. The four-part activity uses an...
Curated OER
Ecosystem Organization
Students examine the structure of ecosystems. In this ecology lesson, students listen to a lecture on relationships among organisms and biomes. Students use the information to create ecosystem organization pyramids.
Curated OER
Populations and Ecosystems
Sixth graders examine the factors that influence the stability of ecosystems. They construct a miniature ecosystem in a jar that includes plants, small fish, and snails, record the population changes over a period of four weeks, and...
Curated OER
Populations and Ecosystems
Sixth graders define terms prey, predator, and scavenger, describe predator-prey relationship, discuss effects of a lack of predators in an environment, and separate the role of the scavenger from that of the predator.
Curated OER
Mark-and-Recapture
Students investigate the mark-and-recapture method for estimating the population of an animal species. They evaluate given data to answer a set of questions.
Curated OER
The Captain And Lake Wilmar
Tenth graders examine the ecosystem of Lake Wilmar through three coordinated performance tasks. They first investigate the effects of pH on freshwater animals by comparing the zooplankton counts from three different areas. They then...
