MS-ETS1-3
The standard
Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
Next Generation Science Standards
What this standard means
Students need to compare test results from several designs, not just pick a winner. They should look for patterns in the data, connect those patterns to the design features, and decide which parts worked best under the criteria and limits.
Mastery looks like a student saying, “Design A was strongest because of the triangle supports, but Design C used less material, so our next version should combine both.” Students often get stuck choosing based on opinion, looks, or one score instead of using multiple data points.
Ways to teach it
- Hands-on activity: Teams build paper bridges, test load capacity and material use, then combine the best features into one revised bridge design.
- Writing prompt: Which two design features from different prototypes should be combined, and what data supports that choice?
- Quick assessment: Give students a small test-data table and ask them to circle two useful features, then explain each choice.
- Real-world connection: Compare phone cases using drop-test, cost, and thickness data, then design a case that combines the best traits.
