Teacher: As you can replace the names of the scientist for others you cover depending on the subject, have the students
generate one timeline and add to it as they go through the class. That may mean you will need to collect and hold on to them.
After – if you can, print out color pics with the correct info to display in class for the remainder of the year.
* It is up to you to either have the scientist birth/death date points on the timeline or when they did their research – be
specific to the students.
Early Earth Scientist Historical Timeline Activity
 List a few of the characteristics the following people have made to science
 List the Dates of the contributions that these people have made
 Francesco Redi:
 Louis Pasteur:
 Alexander Oparin:
 Stanley Miller & Harold Urey:
 Sidney Fox:
 John Needham
***Create a Timeline showing the chronological order of these scientists and their contributions. You will
first put your information on Inventor Cards and then create your timeline. Here is what should be on the
Timeline***ALL 6 Scientists ARE ON THE TIMELINE




Label the time line with dates of the above Scientists discoveries (on the inventor card)
The earliest date should be on the left of the timeline and the most recent date should be on the right
Label each date with corresponding scientist's name & contribution(s) in an organized and legible manner
Be sure your spacing shows a reasonable approximation of the amount of time that elapsed between dates
Questions to Answer
1. In general, what biological topic did all of the scientists work on? Answer: Origin of Life.
2. Where they able to completely answer their question? Explain. Answer: No – only disprove
angiogenesis and create macromolecules.
3. How did the earlier scientists and their contributions directly affect the discoveries of later scientists?
Answer: answers can vary - such as with Needham; Pasteur and Redi re-evaluated his method. Scientist
should be able to recreate experiment and they always review one’s work – peer review
