The Astronomy Center has provided educational resources to introductory astronomy educators since 2003. Over the past 20 years, the rapid pace of discovery has rendered some of our linked resources obsolete. Thus, the Astronomy Center will be decommissioned on March 1, 2022. Our highest quality resources will be retained on ComPADRE.org.

This collection of questions and resources covers the standard first chapter in most astronomy textbooks. The questions are designed to be used for in-class student engagement activities. This topics include the Solar System, Galaxy, and Universe, scientific notation, metric prefixes, special units, speed of light, and look-back time. Animations and illustrations are provided for some of the topics.
This is part of a larger collection of similar astronomy modules from the University of Nebraska-Lincoln. This entire collection covers most of the topics found in most undergraduate introductory astronomy courses.
