Separating A Mixture

In our lab, we had to separate the materials given into seven groups, we also had to write a procedure (steps). Step 1, is to separate the toothpicks, beans, spider, and water from plastic cups onto your tray. Step 2, is to boil the sand, salt, and water in the beaker on the hot plate. Step 3, is to remove the beaker from the hot plate and to filter the sand, salt, iron filling from the water into the plastic cup. Step 4, is to place the magnet into the plastic cup to separate iron fillings from sand and salt.
