K-2-ETS1-3
The standard
Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
Next Generation Science Standards
What this standard means
Students need to test two designs that try to solve the same problem, collect simple data, and compare how well each one worked. They should use observations, counts, measurements, or pictures to talk about what each design did well and what did not work as well.
Mastery looks like a student saying, with evidence, “The tall cup tower held more blocks, but it tipped over faster.” Students often get stuck on picking a favorite instead of using test results. They may also describe looks instead of performance, so keep the test goal clear.
Ways to teach it
- Build two paper bridges, test each with pennies, then record how many pennies each bridge holds before it bends or falls.
- Ask students to write or tell which bridge worked better and what data helped them decide.
- Show two test result charts and ask students to circle one strength and one weakness for each design.
- Compare two lunch bags, one paper and one reusable, by testing which holds more classroom items without tearing.
