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...

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...

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...
Howard Hughes Medical Institute
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...

Some Similarities Between the Spread of an Infectious Disease and Population Growth
Students compare and contrast the spread of infectious diseases and population growth. For this biology lesson, students identify the exponential growth pattern of spreading diseases. They relate this to HIV infection and AIDS.
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 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...

Bacteria and Illness
High schoolers research information on bacterium and their relationship to food borne diseases. In this science lesson plan, students complete internet research to construct and analyze the growth cure of common bacterium...

Human Population Growth
In this human population growth worksheet, students create a graph of human population growth and predict future growth using the data given in a chart. Students identify factors that affect population growth.

Food Safety Lab
Students use the scientific method to investigate the role of temperature in microbial growth. In this food preservation lesson, students set up an experiment with fruit in room temperature and in a refrigerator. They record the...

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...

The Dynamics of Populations
Tenth graders analyze the growth rate of different population. For this biology experiment, 10th graders identify the biotic and abiotic factors that limit population size. They create a poster to show their findings in class.

The History and Future of Human Population Growth
Students create a timeline of human population growth based on guided reading. In this biology lesson, students analyze the trend of how population increased over time. They share their findings in class.

Population Biology
In this population activity, students will compare two population growth graphs and complete four short answer questions. Then students will investigate the factors that influence population growth in 8 fill in the blank statements and 4...

Changes in Ecosystems
In this changes in ecosystems worksheet, students complete 21 various types of questions related to ecosystem. First, they determine whether each statement is true or false based on vocabulary. Then, students determine whether natural...

"Dead-Zones" and Coastal Eutrophication: Case-Study of Chesapeake Bay
Take an in-depth look at nutrient loading, eutrophication, and hypoxia using data on The Chesapeake Bay as an example. This comprehensive presentation includes detailed graphs, photos, and details about the changes in marine organism...

Graphing the Population Explosion of Weeds
Learners are introduced to the seed cycle and draw the specific steps. In groups, they identify the human barriers to the spreading of weeds. After calculating the rate of spreading of the Yellowstar Thistle, they create graphs to see a...
