Do you know the name for the biological study of interactions? A short presentation with accompanying worksheet introduces individuals to ecology. The materials offer a broad overview of the subject and the levels of organization to...

How does your lifestyle measure up in terms of your ecological footprint? Young ecologists examine their impact on the planet using an insightful online calculator. A short quiz asks users to rank the size of their homes, their energy...

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...

From tiny organisms to entire biomes, young scientists examine the interdependent relationships tying all living and non-living things together with this collection of ecology resources.

One size fits all doesn't seem to be the right approach to endangered species. Using a four-part AP® assessment, learners respond to questions that address environmental concerns such as human population changes, invasive species...

How has Gorongosa National Park changed over time? Discover the park's rich history, dating back to primitive human times, through an interactive timeline and scientific reading. The second installment in an eight-part series explores...

Take a walk on the wild side! Episode one of an eight-part series of interactive lessons regarding Gorongosa National Park invites learners to become a part of the citizen science community. Scholars read a brief overview of the trail...

Here is a cross-curricular ecology and technology lesson; your learners create spreadsheets depicting the location and number of groundhog dens in a local park. They research groundhogs and analyze data about where the groundhog...

Here learners get to flex some serious algebraic muscles through an investigation of logistic growth. The properties of the constant terms in the logistic growth formula are unraveled in a short but content-dense...

Earth is sick and needs our help! Read the children's book Planet Earth Gets Well to explain the various problems facing the planet, discussing what young conservationists can do to heal the planet along the way. A great Earth...

The most popular AP science exam, Biology, also maintains the highest passing rate. The College Board releases old test questions covering trichomes and much more, along with statistics and scoring guidelines to help scholars study for...

Practice exercise on population ecology.

This lesson begins with a PowerPoint slideshow that covers important ecological concepts about biomes, limiting factors, carrying capacity, and population growth. Young scholars will look at the population dynamics involved with the...

Create the parameters of your own ecosystem by choosing which producers and consumers live there. Visualize how the food web operates and species populations change. This simulator mimics the food web within a typical ecosystem and gives...

Take this five-question, self-checking quiz on population dynamics in ecology.

See how ecosystems are organized into several different levels, and an ecosystem can be studied at any one of the various levels of organization.

Learn what happens to different populations of organisms as their ecosystem changes. Design your own experiment and make your own guesses with what the result will be with this virtual ecosystem. Also experiment with producer/consumer...

Adjust the number of fish in a lake to be tagged and the number of fish to be recaptured. Use the number of tagged fish in the catch to estimate the number of fish in the lake. (Free usage is limited to five minutes per day.)

In this set of learning modules, students examine the impact of hurricane weather on the El Yunque rainforest in Puerto Rico. They learn about hurricanes, producers, consumers, and the food chain, and how disruptions in organisms'...

Given scenarios, illustrations, or descriptions, the student will identify the process of ecological succession and the impact that succession has on populations and species diversity.

Students discover that variation in plants allows some varieties to survive in near-drought conditions. Next, students learn that different types of rabbits prefer to eat different varieties of plants. Students make the connection...

This lesson will introduce the carrying capacity and show how it affects a population. It is 2 of 4 in the series titled "Carrying Capacity."
