Activity

Magnets: fishing game

Summary: 
Students pick up fish with magnets. The fish have different kinds of metal at their mouths so some won't catch. Can be used as a free experimentation activity.
Science content (2016 curriculum): 
Physics: Motion and Forces, Newton’s Laws, Gravity (K, 2, 6)
Science topic (2005 curriculum connection): 
Physical Science: Force and Motion (grade 1)
Lessons activity is in: 
Materials: 
  • Paper cut-out fish, each with a paper clip, staple or aluminum foil strip at their mouth. Several of each kind for each student.
  • Magnet on a string, attached to a rod, for each student
Procedure: 

Students catch fish, and figure out which ones won't be caught by the magnet.

Discussion:
The paper clip and staple fish mouths have iron in them, so are attracted to the magnet.
The aluminum is not attracted to magnets, so these fish cannot be caught.

Notes: 

Alternatively, use a commercial magnetic fishing puzzle.
