Tomorrow you must bring in a mini-book describing the groups on the periodic table.
 
Think of each group as a chapter or section in a book.  Each section should include:
  •  The list of common properties of that group.  For example are they very reactive or non-reactive.  Are they all metals, non-metals, or metalloids.  Are they hard solids or all they all gases.
  • The number of valence electrons (electrons in the last orbit) in each group.
  • The list of each elements in each group.
  • A picture representing one of the elements in each group.
The groups are:
 
Alkali metals
Alkaline Earth metals
Transition metals
Boron Group
Oxygen Group
Nitrogen Group
Carbon Group
Halogens

Lathanides (not really a group)
Actinides (not really a group either)
