What tactics were used on the battlefield in World War I, and what were their good and bad points?

Question

I've looked up as much information as I can.but condensing it into a few dot points and illustrations and cue cards that can be read out in under 5 minutes without confusing everyone...it's a little hard (by the by, I'm in Year 10).
