Handing out the specimens is always fun.  It’s like handing out cupcakes!  The students love it. LOL

Yep, the students line up with their trays and receive this totally cool gift.  Yes, the specimens do have a smell, but not as bad as when I was in school.

For this experiment, I made a worksheet for them to fill out.  It had fill in the blanks and very little sketching.  I wanted them to really work hard on the dissection instead of spending most of their class time sketching.

I used the following websites to put my worksheet together.

I picked some things from each link and added some things of my own to make a good worksheet.  You can do the same or just use their worksheets. 🙂

As always we begin our experiment by looking at the exterior of the specimen.  We found all to be females and thankfully none had eggs.  I don’t like dealing with the eggs.  blah….

Then we move to the inside.  Love, love, love the double injected specimens.  Arterial system is injected with red latex and the hepatic system is injected with blue latex .  Thumbs up all around!

I think all of the students were glad when this was over.  It got busy real fast and I didn’t get as many photos as I wanted.  You can see previous post with some great photos.
