This activity has students formulate explanations and models that simulate structural and biochemical data as they investigate the misconception that humans evolved from apes. Students should recognize that present-day species evolved from earlier species and the relatedness of organisms is the result of common ancestry. They will also discover that similarities among existing organisms provide evidence ... Full description.

In this activity, students experience one mechanism for evolution through a simulation that models the principles of natural selection and helps answer the question 'how might biological change have occurred and been reinforced over time?' Students will discover that species evolve over time and evolution is the consequence of the interaction of the potential for a species to increase in number, the ... Full description.

This lesson provides an overview for a unit on natural selection. As part of the introduction to the unit, students will have a chance to participate in a discussion around their ideas about evolution. They will also be given information about the goals and expectations for the unit, both in terms of the topics covered and the kinds of work that will be expected from them. Finally, they will be asked ... Full description.

This lesson will help students develop an understanding of natural selection, specifically, how it unfolds from generation to generation. The Motivation section introduces a species of bird that became (over millions of years) numerous species, through adaptation. The Development section is a hands-on activity that demonstrates how populations change little by little, generation by generation, due ... Full description.

This information will provide students with an opportunity to understand the ideas proposed by Jean Baptiste de Lamarck in 1809. Lamarck was an eighteenth century naturalist who came to the idea that organisms change over time. Among other things, he proposed a mechanism for cumulative change that was dependent on the needs of organisms and resulted from the use or disuse of particular body parts. ... Full description.

This information will introduce students to Darwin's model of natural selection in the same way that they learned about Paley and Lamarck. First, they will read an excerpt from Origin of Species and answer questions about it. Then, they will have an opportunity to consider the example of artificial selection (like pigeons or dogs) and think about how this process relates to Darwin's argument. Finally, ...

This lesson has students think about two important components of Darwin's model of natural selection in greater detail. First, they will have an opportunity to explore the natural variations present in a variety of organisms. Specifically, they will examine sunflower seeds and Wisconsin Fast Plants. Next, they will use data and graphs of that data from an artificial selection experiment to consider ... Full description.

This lesson will provide students with an opportunity to use their understanding of the natural selection model to explain phenomena. For this case they will be asked to account for the bright coloration of and the similarity between monarch and viceroy butterflies. In order to do this, they will work in groups to develop a Darwinian explanation using the narrative structure developed in previous ... Full description.

This lesson has students develop a Darwinian explanation for the sexual dimorphism seen in coloration between the male and female ring-necked pheasant. Students will work in groups to develop their explanation and craft a research proposal to bolster some part of their explanation. Students will participate in a simulated grant funding competition in which they will present their explanations and ... Full description.

This resource will help teachers deal with common misconceptions about evolution, those that are simple misunderstandings and others that may stem from purposeful attempts to interfere with the teaching of evolution. First, five common misunderstandings about evolution and how it works are examined. They include the origin of life, ladder of progress, randomness of evolution, trying to adapt, and ...
