  1. Which criterion should guide solutions for helping bikes stay upright at the park?

    • moves 40 books with no drops and easy steering
    • holds ten bikes securely in wind
    • removes the most visible particles in under two minutes
    • holds 2 kilograms using limited materials

  2. Which evidence is a strength of the thicker deck?

    • fits many bikes
    • holds many books securely
    • adds support under the load
    • holds each wheel in place

  3. Which tradeoff should engineers consider for the clear plastic cover?

    • can overheat plants on sunny afternoons
    • raises soil temperature quickly
    • protects seedlings without trapping as much heat
    • it has no constraints at all

  4. Which final design best uses evidence for moving library books without dropping them?

    • use slot racks with a wider base
    • use a rolling bin with smaller sections and swivel wheels
    • combine panels near classroom doors with simple route signs
    • add triangle braces under a thin deck

  5. Why compare soft wall panels and floor route signs before choosing?

    • tests cannot improve designs
    • the first idea is always best
    • each solution may meet the criteria in different ways
    • criteria should be ignored

  6. Which criterion should guide solutions for keeping a model bridge from bending?

    • keeps seedlings between 15 and 25 degrees Celsius
    • removes the most visible particles in under two minutes
    • moves 40 books with no drops and easy steering
    • holds 2 kilograms using limited materials

  7. Which evidence is a strength of the clear plastic cover?

    • holds each wheel in place
    • filters quickly
    • raises soil temperature quickly
    • fits many bikes

  8. Which tradeoff should engineers consider for the coffee filter?

    • catches fine soil particles
    • it has no constraints at all
    • water passes through slowly
    • filters quickly

  9. Which final design best uses evidence for reducing hallway noise near classrooms?

    • use a removable clear cover and vent it at midday
    • pour through mesh first, then a coffee filter
    • add triangle braces under a thin deck
    • combine panels near classroom doors with simple route signs

  10. Why compare deep rolling bin and flat cart before choosing?

    • the first idea is always best
    • tests cannot improve designs
    • criteria should be ignored
    • each solution may meet the criteria in different ways
