Theory Timeline Project
Project Directions:
Choose a theory from the list below. Research the history of your theory and create a timeline.
You will present your timeline in class. Construct the timeline using Padlet* (want to use another
platform? – clear with Mrs. Kreutzer first). When presenting, make sure to discuss why the
theory is pivotal to biology.
