Judging Between Designs is a free printable Grade 3 to Grade 5 science worksheet on comparing multiple solutions against criteria and constraints, aligned to Common Core standard 3-5-ETS1-2. It prints 8 questions with an answer key on its own sheet of paper, in 25 versions that each ask different questions, so no two pupils in the class work from the same page.

3-5-ETS1-2

NameDate

Circle the best answer.

1.Three filters are tested. What should the comparison be based on?
  • A.Which took longest to build
  • B.Which looks cleanest
  • C.Measured performance against each criterion, with constraint failures removed
2.What makes a comparison honest?
  • A.Using more criteria
  • B.Scoring your own last
  • C.The same evidence and the same standard applied to every design
3.Why should solutions be generated before any is evaluated?
  • A.It is traditional
  • B.Evaluating early narrows the field before the best idea appears
  • C.It fills time
4.Why record why a rejected design failed?
  • A.Part of it may solve a later problem
  • B.To justify the rejection
  • C.It is not worth recording
5.Two designs score identically. What is a defensible tie-break?
  • A.Whichever was built first
  • B.A criterion agreed in advance, such as cost or ease of repair
  • C.The teacher decides silently
6.Two groups score the same design differently. What should happen?
  • A.Keep both scores
  • B.Average the scores quietly
  • C.They agree what the criterion means and rescore
7.One design meets every criterion but costs twice the budget. What follows?
  • A.It wins on merit
  • B.The budget is ignored
  • C.It is ruled out, unless the budget itself is renegotiated openly
8.A design fails one criterion badly. What is worth recording?
  • A.Only that it failed
  • B.Nothing
  • C.Which criterion and by how much, in case the design is revised
