Population Dynamics: The Predator-Prey Lab
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...

Population Biology - Biology Teaching Thesis
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...

biology - 9th Grade
The clear cartoon style slides in this presentation contain details that affect population growth. Natural disasters and other external factors are listed as density independent factors, and density dependent factors, such as competition...
Curated OER
Carbon Monoxide and Population Density
Tenth graders investigate the carbon monoxide level at a fixed latitude to determine if there is a relationship to population density. They download data sets and generate a graph, and find locations using the Earth's coordinate system....
Curated OER
Population Biology
Students define the following terms: predation, competition, carrying capacity and population. They can explain the patterns of growth and the limitations of growth. Students explain the difference between density-dependent and...
Curated OER
Population Densities
Students explore biological impact by completing a worksheet in class. In this animal population lesson, students utilize river rocks and jars to conduct a coqui frog population role play activity. Students define a list of amphibian...
Curated OER
Population Density In Fish
Students investigate how a population of fish multiplies in an ecosystem and the kinds of things that must be done to maintain a healthy population balance with other organisms that live there. They conduct an experiment to test the...
Curated OER
Population Dynamics
Students are divided into groups, each group goes to a randomly selected area of the field. They lay out a one square meter plot. Using string to mark the square. Students identify some sort of vegetation that is easy to count within...
Curated OER
Annual Wetland Plant Diversity Survey
Students locate an area of marsh and, by measuring the total number of individual plants in a sample area, determine whether purple loosestrife population density is correlated to the total plant diversity of the community. They...

Population Vs Consumption: Which is a Bigger Problem for the Environment & Who is Getting the Lion's Share of the World's Resources?
Students develop critical thinking and awareness about the complexity of natural resource use, wealth distribution, population densities, poverty, and the environment. They think about people living in different parts of the world and...
Curated OER
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.
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...
Curated OER
Population Dynamics of Growth of Drosophila
Students investigate population dynamics such as variation in density of females, composition of food sources an environmental factors such as light and temperature on Drosophila. They then relate their findings to human populations and...
Curated OER
Welcome to Populations!
Students define what population is in their own words. In this biology lesson, students explain different ways to measure population density. They interpret population graphs.
Curated OER
Grasshopper Mark and Recapture (GMR)
Students estimate the density of a population of insects (grasshoppers) at a given life cycle stage in a given type of habitat.
Curated OER
Chesapeake Bay Population Studies
Students determine how to use a quarter meter quadrant to find population density, relative density, frequency and how to calculate a diversity index while participating in a virtual field trip. They study how to establish a Correlation...

Ecology: Factors Influencing Animal Populations
Young scholars assess the factors affecting animal populations. Working in groups they define specific vocabulary terms and complete several activities from "Project Wild."
Curated OER
Marine Protected Areas (MPA)
Ninth graders explain the purpose of MPA's. In this biology lesson, 9th graders identify MPA's in Southern California. They simulate coastal sampling using candy from two buckets. Students analyze their results and share it with the class.

Urban Ecosystems 5: In Defense Of Cities
Learners explain that while cities have unattractive features, the density of human life enables energy efficiency, mass transit, recycling, and other benefits which are difficult or impossible in rural areas. This is the fifth in an...
Curated OER
Population Dynamics of Growth of Drosophila
Students experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...
Curated OER
Fish and Zooplankton Through Remote Sensing
Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

Life Beyond the Fifty Yard Line -- An ecological look at our backyard
Students, in groups, stake out and rope off their study area, do population counts and density studies. They construct a map of the whole area, collect plants and insects, and mount and identify the organisms using keys.
Curated OER
Cactus Wheel
Students explore plant biology by conducting field experiments outside of class. In this desert plant lesson, students discuss how cacti thrive in such dry climates and how dense their populations are. Students utilize action cards, a...

White-tailed Deer: Beauty or Beast?
Students use study guides and videos to discuss the positive and negative impacts of white-tailed deer populations. In this wildlife management instructional activity, students view slides and discuss the natural history and value of...
