There are several components to this activity:
-The big band and nebular hypotheiss slides (from the power point presentation of the same name) have been shuffled. Cut these out and have students try to place them in order. This is a good review activity or can be used as homework.
-After they have arranged the slides, have them write one, small phrase beside each that "summarizes" the point that each slide is making.
-After students have shared phrases and you have regrouped as a class, pass out the first two slides (a breakdown of the big bang and nebular hypothesis). I often call this the Big Bang in bullet points. It will help students to memorize the steps involved in the formation of our universe and the planet using teacher made "bullet points".
