MS-ESS1-3
The standard
Analyze and interpret data to determine scale properties of objects in the solar system.
Next Generation Science Standards
What this standard means
Students need to use data, images, drawings, and models to compare solar system objects by scale. They should read tables, measure from images, use ratios, and make claims about size, distance, layers, surface features, or orbits. The focus is not memorizing planet facts. It is using evidence to figure out patterns and differences.
Mastery looks like a student saying, “The volcano on Mars is much larger than volcanoes on Earth, and the image scale supports that.” Common trouble spots are mixing up diameter and distance, ignoring units, treating pictures as if they are to scale, and making claims without data.
Ways to teach it
- Have students use clay or paper circles to build scaled diameters of Earth, Mars, Jupiter, and the Moon from a data table.
- Ask students to write a claim comparing two solar system objects, using one number and one image detail as evidence.
- Give a three-row data table and ask students to identify the largest orbital radius, smallest diameter, and one supported comparison.
- Connect to map apps by comparing zoomed images, asking why scale bars matter when judging crater or volcano size.
