Limiting Factors to Population Growth: Graphing Population Growth
If any of the limiting factors in an environment change, both animal and plant populations also change. The video explains two different models of growth and the impact of limiting factors. It highlights the carrying capacity of an...

Finding the Basal Area of a Forest Plot to Determine Stocking Levels
Students use graphs and plots to measure the basal area and stocking levels. For this graphing instructional activity students work in the field the use their data to help them complete a lab activity.

Maintaining Strong Fisheries
Students play a game about the life cycle of a blue crab in order to witness the causes of changes in the crab population and discuss what a resource manager could do to keep a stable crab population. Students then create a game titled...

Investigating Space Requirement of Seed Plants
Students use scientific methods to investigate the effects of overpopulation of seed plants on growth in a limited living space. Students relate seed plant population findings to that of other organisms.

Population Dynamics
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...
Illustrative Mathematics
Logistic Growth Model, Abstract Version
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 activity. Moving...

Water is a Heat Sink
One of the key objectives of Europe's Copernicus Earth program is to monitor the temperatures of the oceans and seas on Earth. Young scholars learn the effects of different heat capacities through two experiments. These experiments...

Computer Simulation of the Sonoran Desert Community
See how changes in initial populations and parameters affect a biological community. Individuals use a special software program to simulate a desert community with five species. They adjust initial populations to see how the community...
National Park Service
Climate Science in Focus: A Streamflow River Study
Data speaks, but it's our job to determine what it's trying to say. Young scientists explore the changes in weather and climate using data from the Yosemite National Park in a six-day unit. Learners first compare weather and climate and...

Ecology Study Guide
In this ecology study guide, students fill in a table about producers, consumers and decomposers, they draw the water cycle, they fill in diagrams about cell respiration, the food pyramid, protein synthesis and nitrification, population...
Curated OER
Population Biology Case Study
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...

Making Connections, Linking Population and the Environment
Young scholars find out that all habitats have a carrying capacity. They explore how the world's human population has grown markedly in the 20th century, and that humans impact environmental health. Students investigate that people can...

A Piece of Cake: Ocean Communities
Students explain habitats. In this model based lesson students create a model to help describe a habitat that is typical of deep-water. Students will describe how organisms such as coral and sponges add to their habitat.

Population Growth
High schoolers examine the factors that affect population growth such as, the length of life cycles, carrying capacity and competition. In this population activity students conduct an experiment on population growth and collect data and...

Designing and Floating Boats
Students participate in an experiment to determine if a toy boat will sink or float. They make the boats out of different materials and determine its carrying capacity by adding pennies. They graph their findings on a classroom graph.
