The transit of Venus is a rare astronomical event that has been well documented throughout history. The most recent transit occurred in June of 2004, and the one before that took place more than 100 years earlier in 1882. This site from the South African Astronomical Observatory provides information and first-hand observations of the 1882 event from Wellington, South Africa. Just prior to the event, an observatory was erected at the Huguenot Seminary for girls, and some of the historical observations made from that site in 1882 are provided here for your perusal.

This web page contains a homework assignment that asks the student to solve problems based on the launch and flight of a rocket. Developed as an alternative to traditional textbook homework, this item is based on the work of the Activity Based Physics project (ABP). Students must make estimations and build their own mathematical models to determine which concepts of classical mechanics apply to each section of the problem set. Topics covered include kinematics, Newton's second law, conservation of energy, and projectile motion. This item is part of a larger collection of alternative homework assignments designed for introductory physics students. Each assignment poses a series of questions about a single context. To successfully complete assignments, students must think critically about how the physical situation could be represented by mathematics.

This astronomy program is designed for middle school children in out-of-school-time settings. The program explores basic astronomy concepts (like invisible light, telescopes) and focuses on the universe outside the solar system (stars, galaxies, black holes). The program is structured for use in a variety of settings, including astronomy days, summer camps, or year-long afterschool programs. Although session activities build concepts sequentially, each session activity is designed to be freestanding as not all participants may attend every session. A manual provides background information and descriptions of how to conduct each activity. A companion website provides additional information and resources for the program leader.

The lithograph contains a Hubble Space Telescope image that shows M82, an edge-on galaxy, undergoing a frenzy of star formation. The text explains the possible causes of the galaxy’s unusual appearance and star-birth activity. The accompanying classroom activity is a curriculum support tool designed for use as an introductory inquiry activity. It can be incorporated into a unit that has a scientific inquiry and/or a galaxy evolution theme. During the classroom activity, In Search of … Starburst Galaxies, students use the lithograph images and text to generate questions about the cause of the starburst, a rapid rate of star formation, in M82. They also conduct research to answer their questions. Students then identify the galaxy they think is responsible for igniting the star formation in M82, and must provide evidence to support their choice.
