Assignment for next week: Though many extinction events have occurred over deep time,
scientists have identified six major extinctions. Research these extinction events and write a 2-
page (or more) summary, in paragraph form.
Include:
1) When the extinction events occurred.
2) What was the likely cause of each extinction event.
3) What were/are the consequences.
– Percent losses of species or major groups.
– How fast did the extinction event occur?
4) You should write a substantial final paragraph detailing the sixth extinction event.
5) Cite sources at the end of your paper
– Choose these sources wisely, i.e. reputable science-based sites, and not Wikipedia
– At least three citations.
– Example of a reputable source
Direct quotes are rarely used in science writing; instead you should paraphrase information (click
here for a tutorial about using your own words to summarize others’ writing).
As always, use proper punctuation, capitalization, sentence structure, and grammar; double-
space your paper, and use 12-point Calibri font and 1” margins. You will lose points if you don’t
follow the proper formatting.
