In this video, Sabrina Cruz will briefly explain the process through which a star glows and will also discuss the factors that affect a star’s brightness. All stars create energy in their core through nuclear fusion, a process through which hydrogen molecules fuse to form helium molecules. This generates energy that moves to the surface of the star as heat and light, and makes the stars glow. The amount of power a star has and its distance from us helps determine its brightness. For example, Betelgeuse is a gigantic star with 10,000 times power than the sun, but because it is located far away from us, it appears much dimmer and smaller than our sun.  

This video satisfies the 5-ESS1-1 requirement of fifth-grade science proficiency.

Students who demonstrate understanding can: 5-ESS1-1 Support an argument that differences in the apparent brightness of the sun compared to other stars is due to their relative distances from Earth.
