Amplify. Student Assessment | Integrated Grade 8 Form A Segment A 2 A student is investigating the strength of electromagnets she created using batteries, wire, and nails. -— Number of coils around nail She uses two different-sized nails and varies the number of coils of wire around the nail to test to see how many paper clips each configuration can lift. She makes a data table of the results. Trial Length of Nail Number | Number of Paper (in centimeters) | of Coils Clips Lifted A 11 2 1 B 8 5 1 C 11 10 3 D 8 10 2 E 11 15 4 F 8 15 3 The student hypothesizes that the number of coils has a cause-and-effect relationship on the strength of the magnetic devices she made. Which would be the best way for the student to test the devices to be sure that her hypothesis is accurate? She should give the devices the same number of coils and retest them. She should increase the distance between the devices and the paper clips. She should repeat the same tests on each device again to collect more data. ap o She should use just one length of nail and test more numbers of coils, including O coils.
