This activity teaches students how to determine the sizes of stars by using simple representations and manipulating the mathematical equations which are illustrated and demonstrated within this lesson. It is important for students to generally comprehend the size, mass, and density of stars. As they complete this lesson, students will be able to explain the relationship between radius and mass among a list of stars, understand how a binary star system's orbit can cause changes in the observed brightness of the system, and determine the diameters of stars by analyzing data and manipulating equations.
