Crash Course: Biology
Imagine an entire biology course in one collection of 40 videos! Based on the AP Biology curriculum, viewers learn about the things that make up living things and the processes that keep organisms alive. They also learn how to identify...
Lesson Planet
Crash Course: Ecology
Viewers take a Crash Course in Ecology with a 12-video collection that takes a look at where organisms come from, how they interact, and how they influence their environments. The videos, appropriate for in class or remote learning, use...

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....
Lesson Planet
Populations
The largest concentration of free-roaming wildlife in the continental United States is found in Yellowstone National Park. A video describes the three main types of population interactions: mutualism, commensalism, and parasitism. It...
Lesson Planet
Ecosystems
Living and non-living things are both a part of an ecosystem. A video begins with ecosystem interactions using biotic and abiotic factors. It also covers food webs, limiting factors, and logistic growth. As a real-world connection, it...
Lesson Planet
Populations and Human Impact on the Ecosystem
A respectful resource is available to support your ecology lecture. Introduce the population concepts of limiting factors and carrying capacity and then examine the example of a deer population in northern Arizona. Take a look at the...
Lesson Planet
Factors Affecting Population Size
How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases and...
Lesson Planet
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...

AP: Chapter 54: Ecosystems
A lot of learning is packed into these 23 questions about ecosystems. Advanced biology classes apply their knowledge of communities, productivity, biogeochemical cycles, and human impact on the environment by writing short answers for...
Lesson Planet
Population Limiting Factors ~ Boom or Bust!
There was a situation in the Kaibab desert of Arizona during which the deer population exploded. Wildlife biologists examine historical data using a graphing calculator in order to learn about population growth, limiting factors, and...
Lesson Planet
Ecology, Nutrient Cycles, Populations
You will get much mileage out of this resource. It is three presentations in one! Standard general ecology information is included within these 69 slides. The first segment deals with levels of organization, biotic and abiotic factors,...
Lesson Planet
Energy Flow Through Ecosystems
Middle or high school environmental studies classes will learn much from this presentation on energy in ecosystems. It covers the foundational topics of trophic levels, food webs, and nutrient cycles using informational text and...
Lesson Planet
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...
Lesson Planet
Populations
The typical introductory environmental questions are asked in this two-page worksheet. Emerging ecologists define populations, limiting factors, carrying capacity, and trophic levels. They analyze a population graph and consider the...
Lesson Planet
Change in Populations
The human population reached 1 billion in 1804, and by 2016, there were more than 7 billion! This activity explores how populations in an ecosystem change over time. Through simulations, videos, discussions, and a game, learners see how...
Lesson Planet
Taiga Ecosystems
Introduce your class to another type of ecosystem, the taiga ecosystem, through a reading passage. Class members read the text and then respond to five reading questions about the content of the passage.
Lesson Planet
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...
Lesson Planet
Earth's Endangered Ecosystems
A vegetable garden is an example of a man-made ecosystem. Here, learners explore the natural ecosystems of the world. In groups, scholars determine the problems their assigned ecosystem faces and, as a class, reach a consensus on the...
Lesson Planet
Understanding Populations
How do populations interact with one another? Identify the different types of interactions and how population sizes fluctuate and affect one another using an interesting PowerPoint presentation. Learners explore real-world examples of...
Lesson Planet
Importance of Deep-Sea Ecosystems – How Diverse is That?
When judging diversity of an ecosystem, both species evenness and species richness must contribute. After a discussion of diversity and a guided example using the Shannon-Weaver function, scholars use the same function on two other...
Lesson Planet
Ecosystems and Change
Pairs of ecologists select an animal and investigate an ecosystem from its point of view. This simple activity involves Internet research and putting together a presentation of collected information.
