More on Fish Coloration

Today students started with a BrainPop on camouflage and then competed in a This or That Challenge. There were 15 picture questions based on concepts taught. The students had two choices to pick from, but they were still tricky. In first period, Brittany got a perfect score while Maria S and someone I cant remember only missed one question. In fourth period, Dale got a perfect score and Connor only missed one. Winners were given pencils with fun marine ecology facts on them.

One of the tricky questions was about this blue ringed octopus. Most cephalopods (octopus, squid, cuttlefish) have active coloration which means they can change the color of their skin at will - often changing quickly and dramatically. The blue ring octopus is about 8 inches long or less. This particular octopus is actually venomous and packs enough punch to kill a 26 humans within minutes with one bite of its beak. Whoa!

Students will review some more tomorrow and have a Unit 2 Test on Friday. All Unit 2 assignments are also due on Friday.

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.
