this week in science #9

WHAT WE DID:

This week in science we did a project about crawfish and  perch. First we slice the crawfish, so that we can see inside the belly. We have to name all the parts of the crawfish. Then we have to write what  we learned.  Then we open the perch and when look inside the belly we see the perch  pregnant and it had eggs inside.


WHAT I LEARNED :

This week in science I learned how to work in a group and how to open a crawfish and perch.  I learned
too that when you open the perch it smells bad and you have to open all the windows.

structures and function:  Nicolle and I opened the perch and the two other people opened the skate. The perch and the skate both have eyes, eggs in ovary  and the heart. The similarity of the eyes is that is little and then can see  in  the water but they live in diffrents place. The perch and skate have a heart
