Limiting Factors for Populations
The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a...

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...

Study Jams! Population Growth
Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....

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...

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 instructional activity. Pupils work together to explore the factors that affect deer populations, then...

Population Ecology
A complete study of population ecology is covered by this worksheet. Biology or ecology learners answer questions and interpret population graphs. This can be used as the intended guided notes worksheet or assigned as homework.

Migration Mishaps
Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...

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...

How Many Penguins Does It Take? Studying Carrying Capacity and Limiting Factors
How does a population's habitat determine the size of that population? Teach learners about carrying capacity and limiting factors with an engaging roleplay activity. Class members pose as a colony of penguins who must gather food amidst...

Biomes and Population Dynamics - Balance Within Natural Systems
How large can a population become? The fifth installment of a nine-part unit teaches young ecologists about limiting factors that determine the carrying capacity of species in the Sonoran Desert. Here is a PowerPoint to help present this...

Population Biology
Young scholars 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...

The Ups and Downs of Populations
As the reality of population decline across many species becomes real, pupils learn about the variables related to changes in populations. They complete a simulation of population changes and graph the results, then discuss limiting...

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...

Limiting Factors/Evolution Game
High schoolers play a board game with provided cards which help them realize that limiting factors may restrict an organism in its development and productivity and direct evolutionary pathways.
