New ReviewHow do populations interact with one another? Identify the different types of interactions and how population sizes fluctuate and affect one another using an interesting PowerPoint presentation. Learners explore real-world examples of...

Psychologists study human relationships while ecologist study relationships between organisms in the environment. An introduction to ecology and the related vocabulary benefits scholars as they progress through the presentation and...

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...

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...

After a year of PBS Eons videos, viewers raised some excellent points and questions. The hosts highlight the most common including classification of animals, when a new eon starts, how to pronounce scientific terms, and many other...

What happens to a species when members become separated by changes in their environment? Present young biologists with the ultimate example species—the anole lizard. A brief video describes the origins of the multitude of anole species...

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...

What is DNA metabarcoding? Show your biology class the latest method for studying biodiversity in an ecosystem with a fun, informative interactive. Individuals examine the animal species that compete for vegetation, then learn how their...

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...

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...

The tropics contain about 40 percent of the area on Earth. Viewers take a trip to Peru as an entrancing video from a larger biology playlist explores the region. It explains the facts and theories about the biodiversity near the equator....

Small but mighty! Learners explore the role of microbes in a healthy ecosystem. An engaging instructional activity asks pupils to design an aquaponics system that demonstrates that healthy microbes are necessary to maintain the ecosystem.

Find your niche in the science classroom. Learners study the role of niche populations within an ecosystem and consider the impact of the loss of these organisms. Their investigation includes vultures, honey bees, and mosquitoes.

I'm not lost, I just haven't found my niche. Video discusses niches, including various pronunciations and definitions. It also covers competitive exclusion principle. Video is the 14th in a series of 18.

Never trust a tree, they always look shady. The video explains both primary and secondary succession. It uses examples of volcanic activity, fires, and human disturbances. It is the seventh in an 18-part series.

Discuss how communities and the ecosystem of the earth deal with change. An informative video includes primary succession, secondary succession, climax community model, and intermediate disturbance hypothesis. 

Warblers are small birds that have been known to get caught in spider webs. The video covers community ecology, focusing on the Competitive Exclusion Principle using the example of warblers. It also includes fundamental versus realized...

Introduce ecology and focuses on the first three levels: populations, communities, and ecosystems. An engaging presentation includes descriptions of exponential growth, population density, adaptations, depression versus baby boom,...

The focus of a fossil-based lesson uses graphs and charts that allow young paleontologists to make inferences about events of mass extinction. They must apply their previous knowledge about fossil records in this final lesson of the...

How can you encourage pupils to demonstrate creativity while still meeting the objective of applying technical knowledge? This activity is your answer! Scientists will create an imaginary creature and prepare a graphic organizer with...

Young scientists explore the dark, damp, and dirty world of earthworms in this hands-on life science unit. In order to gain a better understanding of these slimy critters, children first perform a series of investigations before finally...

Each biome has self sustaining communities, but how did these unique and stable communities form? Investigate how these evolved with changing animal interactions.

The living environment, from the interior of a cell to the complex relationships among populations, are queried in this final examination. Learners look at air pollution maps, diagrams of cells, population graphs, and drawing of cells....

The 2005 version of the Regents High School Examination in the area of ecology is as comprehensive as previous years' exams. It consists of 40 multiple choice questions on everything from the structure of DNA to the interactions within...
