A plot of luminosity vs. time is a ‘light curve’. In this laboratory, we will use a light curve to determine the diameter of two stars in a binary system. --------------------------------------- Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

This laboratory consists of two parts. In part A, we will follow Hubble’s method of measuring distances. Using pulsation time periods, we will obtain the absolute magnitude of a Cepheid variable and convert this absolute magnitude into luminosity which will, in turn, give us the distance. In Part B, we will use spectral shift (the Doppler effect) to determine the Hubble Constant. --------------------------------------- Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

This is a concept attainment on the words: affect and effect. These words are easily confused because they are similiar. This teaching strategy has six steps for students to learn about the two words with activities that is facilitated by the teacher. At the end of the lesson, students should be able to learn the difference between affect and effect.
