This web-based curriculum focuses on basic introductory astronomy concepts. The material is presented through interactive exercises, animations, and videos. Adopters can choose any combination of the ten chapters for a particular class. Each chapter... (View More) includes authentic student interaction with actual data where possible. Students master the scientific concepts and reasoning processes that lead to our current understanding of the universe through interactive tasks, prediction and reflection, experimentation, and model building.

Cosmology is an enormous field and the number of educational resources can be a bit overwhelming. This annotated guide includes a sampling of non-technical materials – online and in print - that Astronomy 101 instructors around the U.S. have been... (View More) using. Items were selected based on their level of difficulty (Astro 101 level and below), the likelihood of their being easily available for a college audience, and their potential usefulness for teaching and learning.

The H-R diagram is a scatter graph of stars, a plot of stellar absolute magnitude or luminosity versus temperature or stellar classification. It is an important astronomical tool for understanding how stars evolve over time. Stellar evolution cannot... (View More) be studied by observing individual stars as most changes occur over millions and billions of years. Astrophysicists observe numerous stars at various stages in their evolutionary history to determine their changing properties and probable evolutionary tracks across the H-R diagram. In this activity, students plot both maxima and minima with corresponding stellar classifications for several variables, and then identify the type of variability: Cepheid, RR Lyrae, Mira or Semiregular. This activity includes background information, a teacher guide, a student activity, and accompanying worksheets. The American Association of Variable Star Observers (AAVSO) and The Chandra X-Ray mission have collaborated to develop this activity. (View Less)
