Parasitism

A really gross human parasite is the botfly. You can listen to a podcast about a scientist who was infected with a botfly larvae. Botfly larvae are transferred to humans by mosquito bites and the larvae grow bigger and develop under the skin feeding on the host. This scientist was a bit strange and decided to allow the botfly larvae to develop on his head until it grew enough to leave on its own. A little gross. You can listen the podcast here. Of course then we had to see a video of one getting removed. Also gross. Here's a video from AnimalPlanet, although not the one I showed class.

You can watch a video about the candiru fish in the Amazon that swims into other fish's gills and sucks their blood - not so bad - except urine smells the same, so when people are in the water peeing, it is attracted to the people and swims up their urethras. Ouch.

Computer Lab Etiquette

You are in the computer lab to do work for this class. If you are not doing work, then we will have problems.

Do not pack up early. Work until the bell or until MsJ says.

SAVE OFTEN. And if you save to a key, also save it to your number. If you lose it, you will have to do it again.

If MsJ asks for your attention, stop what you are doing and listen to what she has to say.

You may watch videos about your organism through reliable websites.

You may listen to music through the computer if you have your own headphones. Rule1 MsJ cannot hear it. You get one warning. Rule2 Turn it on and listen – no million clicks and constant changing. Take both ear phones out when MsJ is talking.
