Every species in the world has some type of relationship with another species, whether it be positive, negative, or neutral for each party. Mr. Andersen defines each type of relationship and provides clear examples under each category....

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...

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

Students are focused on the big question: What makes a population grow and how could that growth stop? They use these concepts to help answer the big question: carry capacity, density dependent v. density, independent factors, predation...

Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...

Students research desert species to find where it lives, what it eats, and what species it interacts with directly. Upon completion of research, students construct a web of all the species as a class. This emphasizes the role each...

Learners explore the predator-prey relationship using an interactive game. In this biology lesson plan, students compare their physical attributes. They explain how  predators develop to make it stronger and efficient as hunters. Each...

In this predation or starvation worksheet, students read about the effects of the wildlife service bringing in predators (wolves) to control a deer population. Students calculate the change in the deer population from 1971 to 1980. They...

Students explore the interrelatedness of predators and prey in four different activities. They simulate an aquatic insect, fish, and osprey food chain during a poker chip game, play an M&M game to simulate the relationship between...

Students observe, record and analyze the mortality rates of the monarch larvae that are being held in a controlled environment versus those that are in the wild.

Students explore the theory of natural selection given certain scenarios. In this biology lesson plan, students graph data taken from the experiment. They explain the factors that contribute to the survival of the fittest.

Fifth graders complete five segments of the videodisk, Super Bees, answering various questions throughout. They also work in groups to develop a hypothesis regarding how the Africanized bees have been able to spread so rapidly in the...
