This was an activity with 3 options. Students are grouped and they can work on 1 of the 3 activities. You could stations, but basically I grouped the students by ability. They are coming up with 3 posters related to the cell theory. One is basically writing the cell theory, Two is a Graphic Organizer looking at the Macromolecules, and Three is the Timeline for the Cell Theory. Three needs to be pre-cut and put on notecards.
