Circle the best answer.

1.Why is the magnet's effect a cause-and-effect relationship?
  • A.Because clips are metal
  • B.Moving the magnet nearer causes the clip to move
  • C.Because it is interesting
2.How would you show a pull acts across a gap?
  • A.Measure the distance at which the clip first moves
  • B.Touch the clip with the magnet
  • C.Weigh the magnet
3.A clip does not move at 8 cm but does at 4 cm. What does distance do?
  • A.Distance makes no difference
  • B.Further is stronger
  • C.The nearer the magnet, the stronger the effect
4.A magnet moves a clip through a sheet of paper. What does that show?
  • A.The pull passes through some materials
  • B.Paper is magnetic
  • C.The clip is paper
5.A rubbed balloon picks up small pieces of paper. What is the cause?
  • A.The paper is magnetic
  • B.The balloon is sticky
  • C.An electric charge on the balloon attracts them
6.The steel plate stopped the magnet moving the clip. What does that show?
  • A.Magnets stop working near steel
  • B.The clip was tired
  • C.Some materials block the magnetic pull
7.Two magnets pushed together the wrong way spring apart. What is the cause?
  • A.The air pushed them
