This is an activity on apparent sizes and apparent angles, related to understanding how distance affects what we observe in outer space (the sun, moon, stars, or planets).

"This lesson sets the stage for a discussion of travel in the solar system. By considering a real-world, hands-on activity, students develop their understanding of time and distance. Finally, students plot the data they have collected." from NCTM Illuminations.

This video lesson has the goal of introducing students to galaxies as large collections of gravitationally bound stars. It explores the amount of matter needed for a star to remain bound and then brings in the idea of Dark Matter, a new kind of matter that does not interact with light. It is best if students have had some high school level mechanics, ideally Newton's laws, orbital motion and centripetal force. The teacher guide segment has a derivation of centripetal acceleration. This lesson should be mostly accessible to students with no physics background. The video portion of this lesson runs about 30 minutes, and the questions and demonstrations will give a total activity time of about an hour if the materials are all at hand and the students work quickly. However, 1 1/2 hours is a more comfortable amount of time. There are several demonstrations that can be carried out using string, ten or so balls of a few inches in diameter, a stopwatch or clock with a sweep second hand and some tape. The demonstrations are best done outside, but can also be carried out in a gymnasium or other large room. If the materials or space are not available, there are videos of the demonstrations in the module and these may be used.

What is a googol? Invented by Edward Kasner, an American mathematician who popularized the number in his 1940 book, Mathematics and the Imagination, it is a 1 followed by a hundred zeros. This directed case in estimation and very large numbers was written for a college-level introductory astronomy course, although it could also be used in a variety of other courses in chemistry, planetary science, biology, and mathematics.

This activity aims to teach students about the different layers of the atmosphere. It also aims to teach them which part of our atmosphere is considered outer space and what phenomena occur in each layer.

A introductory look at our understanding of the universe, and how this understanding has changed from Ancient Greece to the contemporary views of today.
This set of activities is designed to help students develop an understanding of scale/distance and ordering the planets from the sun, understanding Earth's position in the solar system, and developing new ways of determining "order."

Following a public hearing format, this case study allows students to explore the scientific and public policy issues surrounding the advisability of a return mission to Mars for further sampling and, more generally, the question of whether or not there is life on that planet. The case was developed for a non-science majors course called "Great Discoveries in Science" and serves to illustrate the scientific method and the importance of interdisciplinary efforts in scientific research.
