The Standard

Analyze and interpret data to compare and contrast the planets in our solar system in terms of: * size relative to Earth, * surface and atmospheric features, * relative distance from the sun, and * ability to support life.

Georgia Standards of Excellence for Science · Obtain, evaluate, and communicate information about current scientific views of the universe and how those views evolved.

What This Standard Means

What Students Need to Do

Students read tables, graphs, images, and planet profiles, then compare planets using Earth as a reference. They use evidence to explain patterns in size, distance, surfaces, atmospheres, and habitability.

What Mastery Looks Like

A student can accurately rank planets by distance and relative size, and distinguish rocky surfaces from gas or ice giant atmospheres. They can cite multiple data points to support a careful claim about whether known life could survive there.

Common Misconceptions

Students often think planets are evenly spaced, diagrams are drawn to scale, or larger planets are always farther from the Sun. They may call cloud tops a solid surface or assume liquid water or oxygen alone proves a planet supports life.

How to Assess It

Give students a data table for Venus and Mars showing diameter, solar distance, surface, atmosphere, and temperature. Ask, "Which is more Earthlike, and which conditions limit life? Cite three data points."

Lesson moves

Ways to Teach It

  1. Give groups planet fact cards and a blank solar system strip; students place the cards, sort by size, and add surface and atmosphere notes.

  2. Ask, "Is Mars or Venus more likely to support familiar life?" Students write a claim and defend it with three data points.

  3. Play Planet Who Am I: read clues about diameter, distance, surface, and atmosphere while teams identify the planet and explain each choice.

  4. Have students choose a NASA probe destination from three planet data sheets, then justify the choice using possible life signs and travel distance.
