This lesson plan presents an introduction to the apparent motion of the Sun across the sky and the way it changes in summer and winter. The goals of the lesson are to recognize the daily motion of the Sun across the sky, defining the main directions of east, west, south and north. The student will also recognize that the locations of sunrise and sunset (for viewers north of the equator) migrate southward ... Full description.

This lesson includes a historical review, starting with the existence of the horizon at sea, proceeding to various studies of the Earth's size and shape, and leading to the attempt by Columbus to reach India by sailing westward. Students will understand the concept of the horizon at sea as evidence that the Earth is round, calculate the size of the Earth using Eratosthenes' methods, and the origin ... Full description.

This lesson introduces students to electromagnetic waves, the concept of photons, and the relation between photon wavelength and energy. This is tied to solar observations at various wavelengths using the many types of electromagnetic waves. Students will discover that electromagnetic waves are a linked oscillation of magnetic fields and electric currents, spreading through space. They will also discover ... Full description.

This information updates a popular statistical summary about hurricanes that have affected the United States this century. That study, which included a tabulation of the largest US losses of life caused by those storms, had no counterpart for earlier tropical cyclones or for casualties incurred elsewhere. In this presentation that work is extended, providing a catalog of Atlantic tropical cyclones ... Full description.

This lesson will help students understand how wild species cope with changing factors in their environment, such as new predators, fewer available resources, more difficult access to mates, and variable weather. The interaction of all of these factors, coupled with the gradual nature of the changes that result, make evolution a complex subject to study. With these hands-on labs, students delve into ...

This activity uses evolution to introduce students to historical perspectives and the nature of science. Students read short excerpts of original statements on evolution from Jean Lamarck, Charles Darwin, and Alfred Russel Wallace, and discover that scientists are influenced by societal, cultural, and personal beliefs and ways of viewing the world and that science is not separate from society but ...

This information is intended to introduce students to the ideas proposed by William Paley in 1802 in the book Natural Theology. His model invokes the supernatural to explain adaptation and is a particularly clear example of the intelligent design ideas that were prevalent at that time. Students will have an opportunity to come to an understanding of the phenomena he was trying to explain, in part ... Full description.

This lesson asks students to take their understanding of Darwin's model of natural selection and begin to think about how it can be used to explain natural phenomena. They will do this by first attempting individually to explain the case of lizard camouflage to provide a concrete example from which to work. Next, they will work within their groups to compile an explanation based on all of their work ... Full description.

This lesson is based on a video of recent field work on a twenty-two year study of finch beaks on a small island in the Galapagos, showing natural selection clearly operating in the wild. The video (which must be purchased) includes vignettes of the life of Darwin, and the Grant family working and living on the island. The lesson includes a video-notes worksheet, which helps to guide viewing for students, ... Full description.

This lesson covers basic methods for finding one's position on Earth. Latitude can be deduced from the height above the horizon of the pole star or of the noontime Sun, while longitude requires an accurate clock giving universal time. The student will understand how finding one's local longitude requires comparing local time with universal time (UT), which may be obtained from an accurate clock, possibly ... Full description.
