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...

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...

Some Similarities Between the Spread of an Infectious Disease and Population Growth
Young scholars compare and contrast the spread of infectious diseases and population growth. In this biology lesson plan, students identify the exponential growth pattern of spreading diseases. They relate this to HIV infection and AIDS.
Curated OER
Population Biology Case Study
Learners 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...

World Population Activity II: Excel
Students import UNEP World population data/projections from either the World Population Prospects: The 2002 Revision Population Database - UN Population Division or a text file. They graph this data by itself, and then along with...
Curated OER
Population Patterns
Students study patterns of population growth in an ecosystem and why populations must remain in balance. They interpret basic population graphs and suggest scenarios about different population growth patterns in an ecosystem.
Curated OER
The Dynamics of Populations
Tenth graders analyze the growth rate of different population. In 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.
Curated OER
World Population Activity I: Excel
Students use Excel to explore population dynamics using the Logistic equation for (S-shaped) population growth. This activity is primarily intended as an introductory tutorial on using Excel.
Curated OER
Species Interactions
Students study the scientific concepts of biodiversity and conservation through the use of basic equations of population growth and hands-on experiments/simulations. The lesson includes a take-home assignment which can be used for final...

Shape Shifters- Trees and the Environment
Students make a tree sculpture. In this trees and the environment lesson plan, students learn about the parts of a tree, discuss what a tree needs in order to grow, find images of trees in art and nature, use various materials to create...

Art Ideas for Your Adopted Tree
Students honor an adopted tree with artwork. For this adopted tree lesson, students find a tree in their neighborhood. They follow the tree throughout the year, keep notes, draw sketches, take photos and rubbings. They make artwork...
