Stars life cycle and using the HR Diagram

Master star life cycles and HR Diagrams! Interactive science worksheet for grades 8-10.

ESRT p. 15 - HR Diagram Review Use the HR Diagram to answer the questions. Based on what you know, where on the chart would the sun fall? Upper left region Close to the center Lower right region Which of the following star types ends up burning brightest? blue giants red giants white dwarfs Which of the following star types ends up being coolest in temp? blue giants red giants white dwarfs Determine which statements are true and which are false. True (5) Stars are classified by temperature and luminosity Stars spend the majority of their life as main sequence stars. The Sun is an average, main sequence star. The mass of a star determines its life cycle. The Sun will become a red giant then a white dwarf. False (7) The Sun is a supergiant. Blue stars are coolest and red stars are hottest. The color of a star determines its life cycle. All stars become blackholes The Sun will become a blackhole. The Sun will supernova procyon b is a main sequence star Use ESRT p. 14 to answer the questions below. Which star indicated the hottest star surface temperature? blue white yellow red Compared with our Sun, the star Betelgeuse is smaller, hotter and less luminous smaller, cooler and more luminous larger, hotter and less luminous larger, cooler and more luminous Which star is hotter and many times brighter than Earth's Sun? Barnard's Star Betelgeuse Rigel Pollux Which two stars have the most similar luminosity and temperature? Betelgeuse and Barnard's Star Rigel and Betelgeuse Alpha Centauri and the Sun Sirius and Procyon B Compared to the temperature and luminosity of the star Polaris, the star Sirius is hotter and more luminous hotter and less luminous cooler and more luminous cooler and less luminous Compared to the surface temperature and luminosity of massive stars in the Main Sequence, the smaller stars in the main sequence are hotter and less luminous hotter and more luminous cooler and less luminous cooler and more luminous The temperature of Spica is closest to 2,500 K 3,200 K 4, 000 K 25, 000 k Bellatrix has a surface temperature of 21, 000 K. What is its color? Red Yellow White Blue What is the relationship between Temperature and Luminosity of Main Sequence stars? As temperature increases, luminosity increases. As temperature increases, luminosity decreases. As temperature increases, luminosity stays the same. Life Cycle of a Star Spelling Matters - Word Bank (This model skips the protostar phase)Black Dwarf Main Sequence Supernova Planetary Nebula Black Hole White Dwarf Main Sequence Planetary Nebula Supernova White Dwarf Black Hole Black Dwarf Star Life Cycle based on Mass Use the image above to fill in the blanks below. An average mass star like our sun begins its life in a stellar nebula. After it has spent a time as a star, it expands to form a red giant. Next, it expands to form a planetary nebula. In its last stage of life, it contracts to form a very small white dwarf star. Eventually it will burn out and become a black dwarf star.A large mass star begins its life in a stellar nebula. After it has spent a time as a star, it expands to form a red supergiant. Next, it explodes into a supernova. In its last stage of life, it contracts to form a very small neutron star.A very large mass star begins its life in a stellar nebula. After it has spent a time as a star, it expands to form a massive red supergiant. Next, it explodes into a supernova.
