(Nature of Science)

Delilah followed these steps of an investigation:

 Touch each metal object with a magnet and lift slowly

 Record observations

Which of the following is Delilah most likely testing?

• all types of metal are attracted to magnets

• each magnet can lift the metal object to the same height

• larger magnets can pick up heavier metal objects than smaller magnets can

• c. Sirius is closer to Earth than Pollux is

• d. Sirius is larger than Pollux is
