Materials: Cardboard, Plastic, Glass, Magnet, Paper, a Steel Nail,
Pencil.
Hypothesis: I think that the strength of the magnet will not be
affected by the products because if it will still be attracted
by metal.
Independent: The cardboard, glass, and plastic.
Dependent: The Strength of the magnet.
Controlled: The size of the magnet, and surface, the steel nail.
Procedure: Step1: Get Cardboard. Step2: Get Metal. Step3: See
if the strength of a magnet work on cardboard. Step4: Get
plastic and repeat the steps. Step5: Get glass and repeat steps.
Step6: Record your data on a sheet of paper.
Results: My hypothesis was not correct. The items I used did
affected the strength of a magnet.
