Last chance to enter the Armchair Taxonomist challenge!

All this month, we've been telling you about a fantastic challenge from the Encyclopedia of Life. Called Armchair Taxonomist, it's an opportunity to research and write about different plants, animals, fungi, and microscopic organisms — and, in the process, help move scientific information from places where it's hard for most people to see, to an open-access sandbox on the Internet.

If you've taken the time to write up an entry, fantastic. We're looking forward to reading them. You've also got a shot at the great stuff up for grabs — including a private, behind the scenes tour of the Smithsonian's National Museum of Natural History. If you've not entered yet, though, this is the last weekend you can. The deadline is Monday, May 20th at 6:00 pm Eastern.

Read all about the Armchair Taxonomist challenge.
