Predator-Prey Simulation

Do your pupils have the misconception that environmental predators are "bad" and harm smaller creatures? The simulation explains, in detail, the important role predators play in maintaining a stable ecosystem. Through web-based research,...

How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases and...

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...

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

The carrying capacity of an environment varies based on the organisms that live there. Using a virtual lab simulation, scholars test two protists living in their own environments and a third environment where both protists live. They...

In this tutorial, students will study populations learning about how interactions can affect size. Tutorial explores competition, predation, and symbiosis.

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...

Learners 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...

Control the spread of a contagious disease. An applet allows pupils to run a simulation on the spread of a disease. Rules govern how the disease is spread and the length of time it takes to recover. Learners view the spread visually and...

The human population reached 1 billion in 1804, and by 2016, there were more than 7 billion! This activity explores how populations in an ecosystem change over time. Through simulations, videos, discussions, and a game, learners see how...
