This is Thanksgiving week for us which means field trips, cooking, book reading and craft projects. But not this year. This year I didn’t want to go anywhere, but wanted to do something different. Plus we have had this dissection kit sitting around here for almost a year, which will go bad if we don’t use it. Just can’t let that happen so I pulled it out right after the boys were finished with breakfast.
MilitaryKid exclaimed, “Oh, so we’re going to do dissections today, cool.”
ScienceKid said, “Not me, I don’t want to do dissections. You can do that, but I’m not.”
I opened the dissection book and started reading the introduction outloud and by the time I got to reading;
“This book will be especially helpful to biology students from the secondary school through junior college and freshman college levels. It will be useful to students in AP Biology courses………… “
SK was hooked into being there with us. Sneaky, aye? No, not me.
And this will be my only warning, if you dislike seeing the insides of things, leave now, do not proceed, although these shots are pretty. They aren’t pretty gross or pretty nasty, they are pretty interesting, and pretty cool, and pretty fun.

Last warning!

We started off with the lowly earthworm. It took the guys little time to pin the worm and make 
that first cut. Notice how ScienceKid who did NOT want to do dissections today, or any day, jumped right in there and took over. MilitaryKid is looking a bit bored too, just watching, but he was OK with that, at least for now.

SK, the kid who did not want to do a dissection, made the first cut to reveal a simple inside:

I had never seen the inside of an earthworm before, and personally, once is enough for this gal. The boys on the other hand liked getting up-close to this thing and looking all the parts over.

They didn’t stop at the butt end but continued on up the other end too and examined everything.

Such good boys.
Next was the crawfish.
SK remarked that he has eaten plenty of crawfish to know what their insides looked like and he’d like MK do this one.

MilitaryKid was thrilled until he tried and tried to pull off and cut-off the outer skeleton.
Yep, ScienceKid let MilitaryKid do just about that much of the dissection

before taking over stepping in. SK was polite about it and explained to MK all about the crawfish’s gill system

You can see that the two of them are really into this dissection business. I never would have thought it would be such a hit! In case you haven’t seen a crawfish’s gills there they are in the center of the photo.

But around this point the boys got tired of looking at the crawfish’s gills and fighting the exo-skeleton. And then I heard, “Oh, my mouth is starting to really water. I’m pretty hungry too. We need to break for lunch Mom.” LOL! The crawfish went into the trash and we had a little break for lunch.
Up next the frog. MK pinned the frog

And even made the first cut

And do you see how SK is out of the picture! He was just sitting back and watching, plotting as to when he could take over step in.

Patience now. Oh, the frogs mouth was examined throughly before the creature was pinned. We found its teeth, and flipped its tongue out of its mouth and thought of blowing up its lungs but decided not to.

MK did a nice job peeling the skin back too. He might make a surgeon after-all, or maybe a paper cutter.

Look closely at this photo. Not at the frog’s guts but at the olive green in the very top of the photo. Yep, SK has taken over stepped in.
Now, I decided to include this next shot since it is such a higher quality shot than the ones I found on the net for frog dissection.

It shows the livers (the grayish-green mass), the heart, oh, and all the other things in a frog’s gut. We did find a great website that we followed throughout our dissection, frog school Using the frog school site helped us to id each and every organ though and it was nice having the ‘thing’ there in person to see it.


Such concentration. Such learning. Oh, that’s the intestines, and stomach, and frog guts.

Finally SK had had enough and turned the frog over to MK.

He tried to examine the backbone of the frog and get to its brain but didn’t have much luck. He still told me at the end of it all
THAT THIS WAS THE FUN-IST SCHOOL DAY EVER.
