I just recieved an invitation from my former elementary school to give a small presentation about Cephalopods and, quite frankly, I have no idea how to go about it. I would be presenting to any interested 4th and 5th graders, and I have about an hour to do it. If anyone has done something like this before, I would appreciate any advice. So far I have a basic powerpoint presentation, some props, and a frozen squid to dissect. This presentation is going to be occuring in conjunction with a field trip to an aquarium which has a few live Ceph specimins. I will be giving said presentation on Wednesday the 21st.
