  1. Question 1

    What pattern does this data show?

    Paperclips picked up0246810121416160 cm101 cm72 cm53 cm
    • A. The further away the magnet, the weaker its pull.
    • B. Magnets only work when they are 3 cm away.
    • C. The further away the magnet, the stronger its pull.
    • D. Distance makes no difference to a magnet.

  2. Question 2

    A class held a magnet at different distances above a pile of paperclips and counted how many it picked up. How many paperclips did it pick up at 2 cm?

    Answer

  3. Question 3

    Why does the class repeat each distance three times and use the average?

    • A. Three is the only allowed number.
    • B. To use up more paperclips.
    • C. Repeating makes the results more reliable.
