NameDate

  1. A class tests a pull on a sled to move supplies across snow without tipping them. What design problem are they solving?

    • move supplies across snow without tipping them
    • slide a supply box under a table safely
    • move books to the reading corner without dropping them

  2. Which criterion should the box design meet?

    • stop within one step of the cone
    • move the box without hitting the table legs
    • make the swing move a small safe distance

  3. What evidence should students record while testing the push design for the soccer ball?

    • whether the object has a bright color
    • which student likes the idea most
    • distance from the ball to the cone

  4. Test result: The gentle foot push stopped closest to the cone. What improvement should the team try next?

    • move the strap lower and test again
    • test a pull from the center of the knob
    • test a slightly weaker push from the same line

  5. Which claim uses the wagon test evidence correctly?

    • The handle-pull design kept the books inside in three trials, so the team can compare how well the design meets the criterion.
    • The team should choose without testing.
    • The criterion should change after every guess.

  6. A class tests a push on a soccer ball to roll a ball to stop near a target cone. What design problem are they solving?

    • slide a supply box under a table safely
    • roll a ball to stop near a target cone
    • move supplies across snow without tipping them

  7. Which criterion should the sled design meet?

    • make the swing move a small safe distance
    • reach the marker with all supplies still on the sled
    • close the door without a loud slam

  8. What evidence should students record while testing the pull design for the wagon?

    • how many words are in the problem
    • whether the object has a bright color
    • how many books stayed in the wagon

  9. Test result: The rope-pull design tipped over only once. What improvement should the team try next?

    • attach the rope closer to the center
    • test a slower push with the same hand position
    • move the strap lower and test again

  10. Which claim uses the box test evidence correctly?

    • The two-hand push moved the box straightest, so the team can compare how well the design meets the criterion.
    • The object name alone proves the design worked.
    • A push or pull test cannot have evidence.
