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 article profiles Harry Hess, who is known as one of the truly remarkable Earth scientists of the 20th century. It describes the historical background of continental drift, ideas upon which his theories were built. The site goes on to discuss the work of Hess as a World War Two naval commander, during which he developed a system for estimating the daily position of German submarines and discovered ...

Danish seismologist Inge Lehmann used seismic signals to study the thousands of earthquakes that occur every year and offer a brief glimpse of what is happening deep inside the Earth. This article profiles a pioneer among women and scientists. It provides an overview of the P-waves and S-waves found in seismic signals and why they are important to our understanding of the Earth's interior, the educational ... Full description.

This activity introduces students to the properties of electromagnetic radiation in a variety of ways. For example, they put the different types of the electromagnetic radiation on trial, selecting the judge, prosecutor, defense counsel, and jury, and learning about electromagnetic energy by arguing the pros and cons of each wavelength. During this activity, students are introduced to the general ... Full description.

In this laboratory activity students will gain an understanding of the National Environmental Policy Act (NEPA) and be able to apply it to a (perhaps hypothetical) community project. In the process, they will learn the methods of investigating an environmental history and integrate this pursuit with sciences of ecology and geology along with environmental land use policy. While engaged in this activity ... Full description.
