Curated OER
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...
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...

Population Biology
Pupils 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...

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,...
LABScI
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...
Science 4 Inquiry
The Ups and Downs of Populations
Life has its ups and downs ... especially if you're an animal! Biology scholars engage in a population study through an inquiry-based lesson. Pupils work together to explore the factors that affect deer populations, then examine the...
Curated OER
Population Growth
Students grow duckweed, observe what happens when an organism population is allowed to grow without predation or competition, view videos about invasive species, and develop a proposal for controlling the growth of an invasive species in...
Curated OER
Predator-Prey Simulation
Students simulate the interactions between a predator population of lynx and a prey population of rabbits. They collect and graph the data, then extend the graph to predict the populations for several more generations.
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
Endangered Species
Students create a postcard about endangered species. In this biology lesson, students identify how human activities endanger other species. They research and recommend ways to help protect them.
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...

A Simple Model for Natural Selection
Do you have what it takes to survive as a fit predator or will elusive prey lead to your extinction? Find out in a creative natural selection activity. Using different colors and shapes of grains to represent different species and...
Curated OER
Scavenger Hunt: Simulating Natural Selection
Students simulate natural selection using pinto beans. In this biology lesson, students identify the factors affecting organism evolution. They record data from the experiment and formulate a conclusion.
Curated OER
Role of Cerci in Escape Responses of the Cockroach
Students investigate the changes in escape behavior in Madagascar Hissing Cockroahes when their sensory apparatus is removed. They use puffs of air at differnt angles to simulate a predator's approach then collect and analyze data on...
Curated OER
The Environment and Interactions of Living Organisms
Students study the environment and interactions of living organisms. They identify abiotic and biotic factors and create a foldable and vocabulary cards. They create a poster illustrating soil and watch a video to study symbiosis.

A Salt Marsh Ecosystem
What a web we weave. Pupils use yarn as the primary resource to create a web depicting the intricacies of a salt marsh ecosystem. They participate in a question and answer session, which leads to an in-depth facilitated discussion about...

A Designed Organism
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...

Oyster Morphs: Adaptations to the Environment
Students demonstrate how organisms adapt to their environment. They examine prey and predators, natural selection, and adaptations by representing oyster morph.
Curated OER
A Tail to Tell
Students observe populations of Lumbriculus to discover some of the adaptations that allow them to live successfully along the shores of ponds and marshes. They also design and perform experiments to test proposed hypotheses for these...
Curated OER
Why Care About Amphibian Population Decline and Malformations?
Students examine the reasons for preserving wildlife. They look at reasons for amphibian malformations and write an essay about the ethical issues that this brings up. They listen to the teacher read quotes about extinction and how the...
Curated OER
Cougar or Human: Which Needs Protection?
Students research the biology and natural history of the cougar. Students conduct Internet research to determine how cougars have been protected by humans and how it is affected by human decisions. Students write about reconciling...

Experiment on Minimal Segment Size Regeneration of Lumbriculus variegatus
The experiment allows students to observe regeneration of tailless and headless worm segments into complete individuals. Data of a completed experiment are included as well as a student activity sheet.

Camouflage and Protective Coloration: A Model of Natural Selection
Students collect data and compare whether protective coloration or camouflage provides better biological fitness in a given environment. They simulate predator prey interactions of two different species and use gene frequencies to...

A Model for Natural Selection- Spaghetti Worms
Does the early bird really get the worm? If so, which color of worm does it prefer? In an exciting and easy week-long field investigation, young field biologists set up a one square meter feeding area for birds. If you have a webcam,...
