This editable worksheet is set up so that biology pupils read four case studies and identify points that are present in each, such as overproduction, heritable variation, struggle to survive, and differential reproduction. They also...

A presentation on Darwin's theory of evolution and natural selection could be a good addition to your biology class. It provides general information about how animals adapt to their surroundings, as well as how organisms create more...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

Do you know the name for the biological study of interactions? A short presentation with accompanying worksheet introduces individuals to ecology. The materials offer a broad overview of the subject and the levels of organization to...

Why is blood donation so important, anyway? Science and health classes across multiple grades benefit from an in-depth look into the need for and process of blood donation. With an emphasis on presenting the topic in a non-threatening...

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

How did that turkey get from the early Aztec culture to your table? Learn about the history of wild and domesticated turkeys in North America, as well as their inclusion in Thanksgiving traditions, with a two-part agricultural science...

Practice exercise on natural selection. This is new content.

Instructional module focusing on Charles Darwin's explanation of natural selection as the mechanism for evolution. Discusses how this force of natural selection promotes changes in species over time. Site also includes an interactive...

[Free Registration/Login may be required to access all resource tools.] An introduction to Charles Darwin and his theory of evolution by natural selection is offered for students. Meet the writers who influenced Darwin to develop his...

Practice exercise on Hardy-Weinberg Equilibrium.

[Free Registration/Login may be required to access all resource tools.] The theory of evolution by natural selection means that the inherited traits of a population change over time. Inherited traits are features that are passed from one...

[Free Registration/Login may be required to access all resource tools.] Covers Darwin's theory of evolution by natural selection.

[Free Registration/Login may be required to access all resource tools.] Do you ever wonder why some birds are big like ostriches and some birds are small like robins? Or why a lion has a mane while a leopard has spots? In the 19th...

Practice exercise on phylogeny.

[Free Registration/Login may be required to access all resource tools.] Overview of the basic concepts behind evolution.

Instructional module focusing on the early work of Charles Darwin. Discusses Darwin's key role in supporting and describing the theory of evolution as driven by natural selection. Site also includes an interactive practice quiz and links...

Create a Snurfle and see whether it can survive in different environments. As you play the game, you will learn about natural selection and animal adaptations. At the end of the game, try the multiple-choice quiz to check your...

Instructional module focusing on Charles Darwin's theory of Descent with Modification. Discusses how slight changes from parent to offspring create variation and potentially create new species over time. Site also includes an interactive...

This simulation allows students to take on the role of a bird and eat different types of peppered moths. Students analyze which types of peppered moths do better in various environments.

Instructional module focusing on why species change over time through behavioral and physical adaptations. Discusses how environmental mechanisms influence adaptive evolution. Site also includes an interactive practice quiz and links...

[Free Registration/Login may be required to access all resource tools.] An organism goes extinct when all of the members of a species die out and no more members remain. Extinctions are part of natural selection. Species often go extinct...
