What This Standard Means
What Students Need to Do
- Students explain that stars are hot objects that produce light, while planets reflect light and orbit stars. They use facts about light, composition, size, and motion to support their explanation.
What Mastery Looks Like
- A student can compare a star and a planet using several accurate physical traits. They can classify an unfamiliar object from clues and explain the evidence behind their choice.
Common Misconceptions
- Students often think stars are smaller than planets because they look like tiny dots, or that planets produce their own light. They may not recognize the Sun as a star or may confuse rotation with orbit.
How to Assess It
- Give students this exit prompt: “A round object reflects light and travels around a star. Is it a star or planet? Explain with two facts.”

Ways to Teach It
Use a flashlight as a star and foil balls as planets, then observe which object makes light and which reflects it.
Write a claim explaining why the Sun is a star and Earth is a planet, supported by three facts.
Sort clue cards into star, planet, or both, then defend one disputed card with a partner.
Use NASA fact sheets for the Sun and Earth to create a comparison chart showing light, composition, size, and motion.
