This Week in Science #9

  
         This week in science I have dissected a specific fish named a perch. I was a life changing experience for how I would act towards Science. In science class the task of the week was dissection and identifying  parts such as the dorsal,the ventral the side vie and the mouth parts. They had 4 selections of animals that e could have picked. In this dissection me and my partner had picked a perch and we had to find out the sex of it. Turns out it was a male because it only have one fin on the ventral( the bottom). Also we had ti draw a illustration of the dorsal of the ventral view and label.
        This week in scince we leard alot of sceintific details about dissection. This week in scince was a very fun and excited week for me because I had to dissect a organism and lable the parts. It was very weird because we had to use scientific language because our teacher didn't want us to be calling parts of animals  he butt or underneath it the bottom part; But the proper wrod for that  would be the ventral view where the anus is located. This weekin science I have learned alot and I would wanna keep learning more about it because it gets weird and I like weird. 
         We had a task to compare and contrast the forms and functions of our and our table mates' organisms. The organism that my pair and I had was a Perch which is  a type of fish that lives in fresh water. Their skin tend to be rough to cut through cut through and at the skate was really heard to cut through as well.  Both animals were marine animals meaning that they liverd in water. Therfore they had tails and fins that helps them breath underwater. The differences was that the skate body was much bigger than the perch's body and the skate eyes were internal with the ventral view and the perch eye was out side  nearthe dorsal view.
