Overview

• For this extra credit you will be reading post on the I freaking love science blog or the evolution facebook page

• The addresses are www.ifls.com and www.facebook.com/evolutionarybiology

• You will read up to 20 posts on the page, and provide a 3-4 sentence summary of the post (example to follow)

• Along with your summaries, you will submit a simple list of the posts you read (for me to use in grading this)

Grading

• Each summary you submit will be worth 3 points– 3 points for a good summary of the entire post– 2 points for an adequate summary that shows

effort but did not really hit on the main points of the post

– 1 point for a partially correct summary that shows you at least looked at the post

Grading contd.

• Sum up the points you have earned = 60 possible points

• Divide by 6 = points that will be added to your test grade

What not to do

• Do not copy other people’s summaries. I will know and I will not give either of you any extra credit

• Do not just read the first part and try and do you summary from the part before the “see more” button. I will be able to tell

• Do not ask for an extension. This assignment is due Tuesday after Thanksgiving.

Sample Summary (Grasshoppers louder over traffic)

• Grasshoppers have songs they use to attract mates. A new study has found that in urban areas, grasshoppers change their song so that they can be heard over the sound of the city. Other animals have been known to do this, but this is the first time it have been observed in insects. Conservationists are concerned that the changes won’t be enough and males and females still won’t be able to find each other.
