Final answer:
To separate metal paper clips from plastic ones, you can use magnetic attraction. Magnetize one metal paper clip and place it close to the other paper clips. The metal paper clips should be attracted to the magnetized one.
Step-by-step explanation:
In order to separate the metal paper clips from the plastic ones, you can use a technique called magnetic attraction. Metal objects, such as the paper clips made of metal, are attracted to magnets, while plastic objects are not.
To separate the paper clips, you can take a magnetic object, like a bar magnet, and rub it along one of the metal paper clips. This will magnetize the paper clip. Then, place the magnetized paper clip close to the other paper clips and observe what happens. The untouched paper clips should be attracted to the magnetized paper clip, as they are made of metal.
