In this handson activity, students explore the relationship between angular width, actual size, and distance by using their finger, thumb and fist as a unit of angular measurement. They should learn to relate angular width to actual size using distance; quantify the relationship between angular width and distance; and understand why the Sun appears smaller from Pluto than from Earth.

This Student Activity Worksheet is part of a San Jose State University ALERT K12 module which teaches middle school students about making reasonable estimates of numbers, volume, mass, and time. Students estimate numbers of books on shelves and jellybeans or dried beans in jars, compare masses of coins, and estimate time by taking their pulses.

This website contains class notes from part of a Geology 101 (physical geology) course. It describes the Richter scale, and how it measures the magnitude of an earthquake by expressing the seismic energy released. The site discusses the properties of seismic waves, mathematical equations used to help determine magnitude, and how seismographs work.
