Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

Physical science starters play with a pendulum in order to experience periodicity. Detailed procedures and a worksheet are included for day one. For day two, learners will use a graphing calculator to help them plot orbit data from a...

Students use the slopes of various curves plotted on log-log graph paper to classify stellar objects as binary stars, supernovae, or active galaxies.The data used in this lesson were obtained from X-ray astronomy satellites.

In this angular size learning exercise, learners read about how astronomers determine the size of objects in the sky by using their angular size. Students are given equations that allow scientists to convert the angular size into...

In this black hole worksheet, students solve 3 problems given the equation used to determine the speed of a falling body using its mass, the constant of gravitation and the distance it will travel.
