This Week in Science #9

What I DID
This week we researched about skates,perches,frogs,and mice.Then we picked which animals we wanted to dissect and we observed its external anatomy.The next day was dissection day and we picked a skate.It smelled really bad so we had masks.I found a liver,intestine,and stomach.

What I LEARNED
I learned that a skates skin is tough to cut through and when you cut a skate you make an I shape under the gills.Also that you cant find a skates heart easily.I never found it.And that a skate has spiky skin.

Structures And Functions
So the other people at our table were doing a frog.There weren't any similarities that I know of.They were too different.However the mouths of the animals were very different.The frog had no teeth with an extra long tongue and the skate had a rough mouth,still no teeth but it felt rough.

What I DID

       So this week we did dissections and we got a giant grasshopper.The first picture is in Ventral View and the second picture is in Dorsal View.In each picture you can see that I have pointed out one of it's Features the head capsule for you.In picture one you get a clear view of the Anterior (which is the head),the Distal (which is the parts far away from the body, in this case the tarsal claws),and Proximal(which are the parts close to the body in this case the trochanter or shoulders).In picture two you can get a clear view of the grasshoppers Posterior(the ends of the body in this case the abdomen or butt).

What I LEARNED

       I guess you can say that one of my AHA moments was when I found out that the grass hopper wasn't all just goo inside like a bug.It was like a real animal with organs and stuff inside.The organs where pretty hard to see but they were there.This animal reminded me of when I studied that spider.Just because I think if I was dissecting a spider it would be like the giant grasshopper.
