An interactive applet and associated web page that demonstrate the corresponding angles that are formed where a transversal crosses two lines. The applets cycles through the four possible pairs of angles when in animation mode. By dragging the three lines, it can be seen that the angle pairs are congruent only when the lines are parallel. When not in animated mode, there is a button that cycles through each the four pairs of angles. The text on the page discusses the properties of the pairs of corresponding angles both in the parallel and non-parallel cases. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

In this lesson, students will explain CRaTER's purpose and how it works. They will also design (using paper and pencil) a cosmic ray detector to answer their own questions. CRaTER's purpose is to identify safe landing sites for future human missions to the moon; discover potential resources on the Moon; and characterize the radiation environment of the Moon. The lesson includes background information for the teacher, questions, and information about student preconceptions. This is lesson 4 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation."

Students write poems using rhyme and meter as they come to understand the mechanical concept of rhythm, based on the principle of oscillation, in a broader biological and cultural context, as seen in dance and sports, poetry and other literary forms, and communication in general. Note: The literacy activities for the Mechanics unit are based on physical themes that have broad application to our experience in the world â concepts of rhythm, balance, spin, gravity, levity, inertia, momentum, friction, stress and tension.
