Has students calculate a scale and then use it to make a time line of the evolution of life. Lower ability might need scale calculated. 5m is a good length. Makes nice classroom decoration if done with colored border paper.
Evolution of Life Scale Timeline
A great visual resource which can be placed around the classroom in a timeline. Really useful to show the concept of time.
Great for arranging by students
I added a couple of 'pre-life' rows to include whole Earth history. Thank you.
