Students obtain remote sensing data to compare and contrast global biomass data with global temperature data.

What a web we weave. Pupils use yarn as the primary resource to create a web depicting the intricacies of a salt marsh ecosystem. They participate in a question and answer session, which leads to an in-depth facilitated discussion...

How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Students explain that while cities have unattractive features, the density of human life enables energy efficiency, mass transit, recycling, and other benefits which are difficult or impossible in rural areas. This is the fifth in an...

Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

High schoolers research abiotic and biotic factors concerning the concept of an ecosystem. Record and analyze data collected. Write a lab report in proper and scientific format with thinking and analytical skills. Work as a cooperative...

Pairs of ecologists select an animal and investigate an ecosystem from its point of view. This simple lesson involves Internet research and putting together a presentation of collected information. 

Tenth graders conduct various activities utilizing the scientific method to formulate a hypothesis, conduct a controlled experiment, collect and analyze the data and communicate their results through a poster. They also identify...

Life has its ups and downs ... especially if you're an animal! Biology scholars engage in a population study through an inquiry-based lesson. Pupils work together to explore the factors that affect deer populations, then examine the...

When judging diversity of an ecosystem, both species evenness and species richness must contribute. After a discussion of diversity and a guided example using the Shannon-Weaver function, scholars use the same function on two other...

Searching for an eccentric way to enhance lessons on ecosystems while ensuring pupils remain creative and motivated? Upon viewing The Lorax by Dr. Seuss, designated groups design and construct a pop-up book that...

Is qualitative or quantitative research more convincing when it comes to climate change? In the eighth lesson during this 21-part series, scholars begin by performing a quantitative analysis of deforestation and urbanization. Then, they...

Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a...

As the reality of population decline across many species becomes real, pupils learn about the variables related to changes in populations. They complete a simulation of population changes and graph the results, then discuss limiting...

Students discover that material and energy uses by a city come from outside the city boundaries. They realize that the pathway of these material is linear instead of cyclical as they are in natural ecosystems.

Students compare and contrast the spread of infectious diseases and population growth. In this biology lesson, students identify the exponential growth pattern of spreading diseases. They relate this to HIV infection and AIDS.

Middle schoolers familiarize themselves with the interconnectedness of species within an ecosystem, and to use this knowledge to evaluate how the removal or decimation of one species can have far reaching effects.

Should gray wolves be removed from Yellowstone National Park? After researching the complex relationships between the various habitats and species at Yellowstone National Park,  including humans, class members take a position...

It's the attack of the invasive species! Young scientists simulate the behavior of an invasive species with a game-like activity. They assume the roles of native plants, invasive plants, and resources and watch the invasive plant takes...

We take paper for granted, while thousands of trees are being made into the paper we toss in the trash. Start a dialogue about paper reduction and recycling in class, and share the negative effects paper production has on our...

Learners construct a defined plot on school grounds and observed patterns in plant life. They count trees, shrubs, cacti and record on a data sheet. They compare data and generate a plant diversity overlook for their school.

Ninth graders conduct an environmental inventory on one ecosystem. They collect data, and write an environmental impact statement on that area. Students explain the interactions between different systems found within an ecosystem....

Fourth graders go on a virtual field trip to five ecosystems. They investigate and videotape a temperate forest in the school's backyard.
