What the standard actually says
Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
Domain: Engineering Design — Using the engineering design process to solve problems — ask, imagine, plan, create, test, improve.
Next Generation Science Standards*Examples and home activities
- Build two different paper airplanes. Test both. 'Which flew farther? Why do you think?'
- Design two different boats from foil. 'Which held more pennies before sinking?'

Lessons that teach this
17 lessons list K-2-ETS1-3.
Week 16
- Wednesday · Science — Students will test a prototype against the criteria, collect data, and use the results to identify what to improve (K-2-ETS1-3).
- Friday · Science — Students will improve a prototype based on test data and retest to see whether the change helped (K-2-ETS1-3).
Week 17
- Monday · Science — Students will build a second, different solution to the same problem so that two designs can be compared fairly (K-2-ETS1-3).
- Wednesday · Science — Students will test two designs under the same conditions and compare their strengths and weaknesses using data (K-2-ETS1-3).
- Friday · Science — Students will use comparison data to recommend a design and combine the best features of two solutions into a final version (K-2-ETS1-3).
Week 18
- Monday · Science — Students will retrace every step of the engineering design process using their own project as the example (K-2-ETS1-1, K-2-ETS1-2, K-2-ETS1-3).
- Wednesday · Science — Students will prepare a showcase display that communicates the problem, the solutions tested, and the evidence for the final choice (K-2-ETS1-2, K-2-ETS1-3).
- Friday · Science — Students will present their engineering project to an audience, answer questions using evidence, and reflect on the whole unit (K-2-ETS1-1, K-2-ETS1-2, K-2-ETS1-3).
Week 34
- Monday · Science — Students will carry out their science fair experiment with three trials for each condition and record results in a data table (2-PS1-2, K-2-ETS1-3).
- Wednesday · Science — Students will finish their trials, find the total for each condition, and build a bar graph that shows the results (2-PS1-2, K-2-ETS1-3).
- Friday · Science — Students will write a conclusion that answers the science fair question with evidence from the bar graph (2-PS1-2, K-2-ETS1-3).
Week 35
- Monday · Science — Students will organize their plan, data, graph, and conclusion into a science fair poster with a clear left-to-right order (K-2-ETS1-3).
- Wednesday · Science — Students will rehearse a 2-minute science fair talk and answer questions about their evidence (K-2-ETS1-3).
- Friday · Science — Students will present their science fair project to a family audience and evaluate what made their evidence convincing (K-2-ETS1-3).
Week 36
- Monday · Science — Students will review the year's science units by sorting portfolio work into topics and choosing their best piece from each (2-PS1-1, 2-LS2-1, 2-LS4-1, 2-ESS2-1, K-2-ETS1-1).
- Wednesday · Science — Students will write a caption for each portfolio piece explaining the science idea it shows and the evidence behind it (all Grade 2 science standards reviewed).
- Friday · Science — Students will present their science portfolio, reflect on their growth as a scientist, and receive awards tied to real skills demonstrated during the year (all Grade 2 science standards reviewed).
