Squid Project
Directions:
You will use the Internet or the booklet provided to you entitled An illustrated Dissection Guide to the
Squid to create a PowerPoint that details the structures that you will explore during the dissection of
the squid with Alaska Sea Life. If you are unable to complete this task using a computer, you may
create a booklet that details the information requested below. You will need to draw the
structures since you will not be able to access them via the Internet.
