Steve's teacher challenged the class to design an investigation to show that a piece of paper's total mass can not change when it undergoes physical changes. Using the same size piece of paper for each trial, Steve decided to examine the paper in various forms. Steve wrote all of his observations in the chart below. (P.8.3)

• mass of the paper remained the same with each test

• color of the paper appeared different with each test

• sizes of the paper affected the mass with each test

• odor of the paper had changed after each new test.

The drawing below shows iron filing surrounding the north pole of one magnet and the south pole of another magnet.

Which area in the drawing has the strongest magnetic field?

(P.8.4)

• the area near the poles that are touching

• the area near the poles that are not touching

• the area in the middle of either of the two magnets

• the area in between the poles and the middle of either magnet
