About This Chapter
How it works:
- Identify the lessons in the Glencoe Earth Science Stars chapter with which you need help.
- Find the corresponding video lessons within this companion course chapter.
- Watch fun videos that cover the stars topics you need to learn or review.
- Complete the quizzes to test your understanding.
- If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.
Students will learn about:
- Determining a star's temperature
- The life cycles of neutron stars

1. Structure of the Sun
Discover the layers of the sun, including the core, radiative zone, convective zone, photosphere, chromosphere, and corona. Find out which layers you can see from Earth. Investigate what sunspots and solar flares are.
2. Types of Star Clusters
Our lesson will explore what star clusters are, the two types of star clusters, and their characteristics and differences as well as how we can figure out their ages using the H-R diagram.
3. Types of Stars by Size, Color and Life Cycle
Learn to identify the different sizes and colors of stars and how they relate to the star life cycle. In this lesson, we'll talk about spectral classification, how many stars there are of each type and the approximate color of the different classes of stars.
4. Relating a Star's Brightness to Luminosity
This lesson will explore how luminosity, apparent brightness, and distance are related to one another using the inverse square law. You'll also learn how luminosity can be gauged based on distance and apparent brightness.
5. Determining the Temperature of a Star
This lesson will explain to you the concepts of a spectrum, electromagnetic radiation, the temperature of a faraway star and how that relates to something known as a blackbody curve and Wien's law.
6. Measuring The Distance to a Star
This lesson will tell you how astronomers can measure the distance to a star and how it relates to the way surveyors measure distances to landmarks right here on Earth.
7. Star Formation: Main Sequence, Dwarf & Giant Stars
Learn how stars are born, beginning with a protostar. Then learn about stars in later stages of life, including main sequence stars, brown dwarfs, red giants, and black holes.
8. Nuclear Fusion & Star Formation
This lesson will explain how the processes of stellar formation leads to nuclear fusion. We'll also define nuclear fusion and hydrostatic equilibrium, and find out why temperature is so important to all of this.
9. Supernova and Supergiant Star Life Cycle
Learn about one of the biggest explosions known to humankind - a supernova. Follow a star's life cycle and learn how a star changes from a red giant to a supernova to a black hole or neutron star.
10. Life Cycle of Neutron Stars
Discover the life of a neutron star, including how it's born after a supernova explosion and how its extreme pressure causes protons and electrons to combine into neutrons. Discover also how pulsars are rotating neutron stars that will eventually slow down to become regular neutron stars.
11. Life Cycle of Black Holes
Learn about black holes, their myths and their reality. Learn how black holes form after stars undergo supernovae and create singularities. Discover how big black holes grow, how scientists find black holes and where black holes are located in the universe.
