NGSS MS-ETS1-2
The Standard
Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

What This Standard Means
What Students Need to Do
- Students compare several possible designs with the same criteria, constraints, and scoring method. They use test results or other evidence to choose an option and explain its tradeoffs.
What Mastery Looks Like
- Students create and use a consistent scoring table for several designs. They select the strongest option using test data and explain where that option performs well or makes tradeoffs.
Common Misconceptions
- Students may choose the design they like best instead of using test data. They may treat criteria and constraints as the same thing, change scoring rules midway, or ignore tradeoffs.
How to Assess It
- Give students data for three water filters, including cost, filtering time, and water clarity. Ask them to score each design in a table and justify their choice with two data points.

Ways to Teach It
Test three paper bridges over the same span, then rank them by load capacity, material used, and construction time.
Ask students to write which bicycle helmet design a school should buy, using price, safety rating, weight, and fit data.
Give teams design cards and constraint cards, then award points for accurate rankings made with an agreed scoring system.
Compare reusable lunch containers by cost, durability, capacity, and waste, then recommend one for a class field trip.
