Human Population Growth in the Future, What are We Going to Do?
Students predict what will happen to human population in the future. In this biology lesson, students brainstorm possible solutions to overpopulation problems. They create a persuasive brochure about their views on this issue.

Populations – The Survival of the Fittest (Part 1)
Students explain in their own words why organisms live together. In this biology lesson, students model what happens to organisms if their environment changes. They explain the importance of evolution.

Human Populations Studies: the Ghost of Populations Past
High schoolers compile data on population distribution and develop survivorship curves using information from cemetery tombstones and obituaries. They develop inferences on the changes in population age distribution in their area over time.
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...

From Restriction Maps to Cladograms
Biology aces analyze restriction maps to determine the relationships among different primate species and then complete a cladogram. Preface this lesson with an explanation of how restriction enzymes are used to create the DNA maps....

Natural Selection
Biology learners tackle evolution-related concepts when viewing this collection of slides. There are no graphics or photos, just notes in bullet-point style detailing adaptations, evidence for evolution, mechanisms for change, and types...

Producing a Strain of E. coli that Glows in the Dark
Students observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...

Understanding and Predicting Changes in Population Size – Exponential and Logistic Population Growth Models vs. Complex Reality
Salmonella poisoning impacts over 200,000 people in the United States each year. Scholars learn about the growth of these bacteria using multiple approaches. Then they apply the same growth calculations to endangered species and think...

Measuring Biodiversity in Gorongosa
Take your biology class' understanding of biodiversity to a whole new level! Ecology scholars use data to calculate three different diversity indices based on the organisms in the Gorongosa National Park. The four-part activity uses an...
Curated OER
Analysis of Data
Learners analyze DNA banding patterns for similarities and differences among individuals and between populations. They examine individual prepared gels then pool the class data to come to an overall conclusion.

Understanding Human Population Growth
You can help students learn about the causes and consequences of our rapidly growing global population
Curated OER
Population Ecology
Here are some ideas to help students understand population growth in ecosystems.
Curated OER
Flower Population
In this flower population worksheet, high schoolers use a diagram of first and second generations of a flower population to complete 2 short answer questions about genotype and allelic frequency.

Oyster Gardens - No Soil Required!
Explore the practice of oyster gardening. Because oysters play a vital role in marine ecosystems and their populations have declined, biologists are transplanting oyster seed to repopulate reefs. After learning about this practice,...

The Influence of Human Activity on the Environment
The surge in human population in the last 2,000 years, due in large part to better health care, has brought a surge in the demand for resources and in pollution. The graphics, photographs, and real-life examples in a thought-provoking...

Wildlife
First, biology pupils research land and marine habitats along the route of skipper Rich Wilson's Great American II. Then, using colored paper clips scattered across a colored paper background, they play the predator-prey game to...
Curated OER
Biological Succession in a Microecosystem
High schoolers investigate the concept of biological succession by simulating the process in a microenvironment with various microorganisms. By engaging in a lab, students determine the factors causing succession and learn population...
Curated OER
Populations and Ecosystems
Sixth graders examine the factors that influence the stability of ecosystems. They construct a miniature ecosystem in a jar that includes plants, small fish, and snails, record the population changes over a period of four weeks, and...

Biology Word Search Puzzle
In this biology word search worksheet, students search for 29 words that are located in a word bank at the bottom of the page. They find words such as chromosomes, alleles, DNA, and populations.
Curated OER
Environmental Limitations
Seventh graders study the environmental factors that affect population growth. In this biology activity, 7th graders create a city following certain criteria. They present their posters in class.
Curated OER
Niches and Adaptations
Young scholars present information about a species, its niche, and adaptations. For this lesson on animal environments, students explore how surroundings can affect a given population resulting in adaptation.
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
Pandemics and Epidemics
Young scholars evaluate data related to population growth, along with problems and soultions: disease cvontrol. They are able to explain how changes in habitat may affect organisms. Students evaluate evolutionary theories and processes.
Curated OER
Genetic Drift
Students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. They run a series of simulations varying allele frequency and population size and then analyze their...
