  • What is friction? (think about the activity with the rolling pencil)
    Friction happens when two things rub against each other. Friction makes things slow down. It can also warm them up.
  • What is a magnet?
    an object that can pull certain types of metal toward itself
  • What kinds of materials can magnets pull through? (think about the activities with the maze, ruler and cup)
    non-magnetic things like cardboard, glass, plastic, wood and water
  • What is motion? (Think about the activity we did with the balled up paper or the sock.)
    movement or a change in position
  • Does this show magnets attracting or repelling?
    Repelling (same/like poles repel)
  • Does this show magnets attracting or repelling?
    Repelling (same/like poles repel)
  • What is a pull?
    a force that brings an object closer
  • What is a push?
    a force that moves an object away
  • What does it mean for a magnet to "attract"?
    pull closer; opposite poles attract (N and S; S and N)
  • What is force? (Think about the video of Grover from Sesame Street)
    a push or a pull
  • Think about the activity we did with the balled up paper or the sock. How did we change the motion of the objects?
    Possible answers: Tossed it in air, threw it harder, hit it. (Reminder: Forces change the motion of an object. Motion can speed up, change direction or stop.)
  • What are poles on a magnet?
    the ends of a magnet; north (N) and south (S)
  • Does this show magnets attracting or repelling?
    Attracting (opposite poles attract)
  • Give an example of a push.
    Various answers
  • What kinds of things are magnets attracted to?
    Metals such as iron, nickel, cobalt and steel
  • What does it mean for a magnet to "repel"?
    push away; same poles repel (S and S; N and N)
