3 ) Explore objects that can be manipulated in order to determine cause-and-effect relationships (e.g., distance between objects affecting strength of a force, orientation of magnets affecting direction of a magnetic force) of electric interactions between two objects not in contact with one another (e.g., force on hair from an electrically charged balloon, electrical forces between a charged rod and pieces of paper) or magnetic interactions between two objects not in contact with one another (e.g., force between two permanent magnets or between an electromagnet and steel paperclips, force exerted by one magnet versus the force exerted by two magnets).

4 ) Apply scientific ideas about magnets to solve a problem through an
engineering design project (e.g., constructing a latch to keep a door shut,
creating a device to keep two moving objects from touching each other such as a

resulting magnetic field (e.g., magnetic poles) and to explain its measureable
effects (e.g., protection from cosmic radiation).
