The second lesson in the series begins with a starter activity discussing wild versus domesticated animals. Then, scholars play a card game, with optional variations, to emphasize artificial selection. Next, they attend a field trip to a...

One of the most diverse environments on Earth is the ocean. Young scientists explore the living things found in the ocean during an exciting seven-lesson unit. Their study includes organisms from plankton to invertebrates...

Bacteria get more resistant to antibiotics every year. Learn the reason for this pattern and how scientists are addressing the problem in a six-week unit. Learners analyze different types of bacteria and their adaptations.

What do you call a bee born in May? A maybe! This first instructional activity in a series of four begins with a starter activity to get scholars thinking about the topic. Then a circus, or circuit of seven activities,...

Use the 5E model to learn about natural selection and selective breeding.

[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...

The concept of interdependence in an ecosystem and its effect on the evolution of populations is further explored through a model of a dam. Students build a dam in the middle of the field, dividing the ecosystem in half to illustrate the...

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.] Meet Charles Darwin and his theory of evolution and natural selection. Understand why adaptations are important.

Darwin's theory of evolution explains how species of living things have changed over geological time in order to survive in the changing environment. A link to a test is provided.

[Free Registration/Login may be required to access all resource tools.] Explains how natural selection favors certain traits in a population so that the organism adapts to its environment, and that changes in the genes over time cause...

Gene pools can change as a result of genetic drift and other mechanisms. This tutorial will investigate how gene pools change and evolve.

How does evolution really work? Alex Gendler sets the record straight on the finer points of evolution, including some common evolutionary misconceptions.

Through informational text, online lab activities, virtual simulations, and video clips, students study the concepts of biological evolution.
