This 120-page guide includes an account of the history of rocketry, starting almost 2400 years ago in Greece, and discusses the contributions of modern scientists to rocketry and the development of the United States' space program. Newton's three Laws of Motion are explained in terms of rocket principles, while a section on practical rocketry discusses propellants, thrust, mass, stability and control systems. Students examine a photo to estimate how many galaxies it contains. Students classify galaxies by color and shape. Estimating Distances in Space.
Students rank galaxies by distance.
The experiments will examine how plants grow in microgravity. The guide contains directions for performing these same experiments in the classroom. Analysis of growth is based on statistics. Back of poster has explanatory text and black and white images. The Seaborg Center will copy videos free of charge.
