    Magnets Attract!

    PLANScouters should prepare the material. The magnet game is best played outside or somewhere that kids can run around.

    DOActivity # 1: What do magnets attract?Beaver Scouts work in groups of two to three to figure out what objects are attracted by magnets and which ones are not. Scoutersgiveeachgroupaboxfilledwithdifferentobjects(pebbles,corks,paper

    clips,keys,erasers,coins,ironneedlesorscrews,etc)andsomemagnets. ScoutersaskBeaverstocategorizetheobjectsinanywaytheywhat.They

    eventually will figure out that some objects are magnetic and some are not. Whenallgroupsaredone,discusshowtheyorganizedtheiritems.Scouterswill

    guide the discussion towards the objects interaction with magnets and how they attract objects made of iron.

    and must figure out how magnets interact with each other. They will soon find out that opposite colour poles attract each other and like colours repel each other.

    should form a magnetic chain by holding each others hands. But they should remember that like poles repel and unlike poles attract.
