Science Review

Gio was a coin collector. He is fond of collecting old coins. He decided that he will make his own metal detector. Choose TWO suggestions that Gio can do to improve his tool in picking up more coins underground.

• attach a piece of wood to the magnet

• lower the magnet so it is closer to the ground

• raise the magnet so it is higher above the ground

• attach a weaker magnet to the tool

• attach a stronger magnet to the tool
