Easy Science experiment?

Question

My little sister-11 yrs old and she's in 5th grade needs to do a science experiment. Do you know any websites then she can go to? To find EASY but get a good read experiment. Or any ideas?!

Answer 1

Experiment with magnets, map out the magnetic lines of force using iron filings.  Place the magnet under a sheet of paper and sprinkle the filings on top. You will see magnetic lines of force.  How is a compass effected by the magnet as it is moved around the magnet.   Does the compass needle line up with a magnetic line of force?

Using several magnets (bar type)   place poles  of magnets  next to each other and see how the line of flux are effected when like poles are near each other vs  unlike poles next to each other. You will have to tape the magnets down to prevent them from moving.  Place metal objects next to the field and see of they distort the shape of the magnetic field.

How does the shape of a magnet effect the shape of its field. (horse shoe, bar, torrodial (circular))

You can sketch the fields with a pencil or snap pictures with a camera.
