Expanding your Horizons: Squid Skin

As an introduction to cephalopods, we watched a video that showcased the awesome camouflaging abilities of cephalopods. Cephalopods include the well known octopus and squid, but also the cuttlefish and a creature called a chambered nautilus.

These molluscs are able to control their color by rapidly changing the chromatophores in their skin.

This week, students will need to watch two videos, answer some questions, and then think about what they would use this ability for.

Video1 - Deep Look - Squid Skin

Video2 - Richard Hammond - Can a Cuttlefish camouflage to a living room?

Optional Video2 - Science Friday  Where's the Cuttlefish?

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.
