Name: Date: Student Exploration: H-R Diagram Vocabulary: giant, H-R diagram, luminosity, main sequence, star, supergiant, white dwarf Gizmo Warm-up In the early 1900s, astronomers identified many star characteristics such as color, size, temperature, and luminosity—or how bright a star is. Using the H-R Diagram Gizmo, you will discover how some of these characteristics are related. Start by moving your cursor over the stars in the Star collection. Star information is d...

Vocabulary: absolute brightness, absorption spectrum, apparent brightness, Big Bang theory, blueshift, Cepheid variable, Doppler shift, Hubble constant, Hubble’s law, luminosity, megaparsec, period, redshift, spectrograph Gizmo Warm-up In 1912, an astronomer named Henrietta Swan Leavitt studied a class of stars called Cepheid variables. These stars change from bright to dim to bright again. Her discoveries led to a method of measuring distances to other galaxies and eventually helped to suppor...
