this week in science #9

This week in science we did a experiment that involved us cutting into some animals. I had to cut open a skate and take out the lungs, heart ,guts, and a lot of other nasty things. When i had to cut it open the rib cage was pretty hard to cut open. It took me some time to cut it open and then i had to take my hand and try to rip the skates flesh open. Then when i did open it i had to dish out some of the water that got stuck in side of the skate was that was pretty nasty. I cut off the tall and it was cool it had tons of spikes on it. So that's what i did in science.

This week in science i learned that the skate is in the ray and shark family. I think that is awesome that's pretty cool. I also learned that the skate has lots of spikes on its body so if any animal tries to eat it the animal would get hurt. I learned there is over 1000 different kinds of skates in this world. The skate has sharp teeth but they are very small.

We had to dissect the skate and the perch. Some of the structures to me that was the same was the skin flesh whatever you want to call it but it was really hard to cut through. They both had small sharp teeth and they both some strong and long gills. Then some things that were different was that the skate you had to cut ope the gills o see inside and it was kinds hard but the perch we just ripe it open like nothing. Also the skate has lots of spikes on top of its body and the perch had lots of scales.
