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.

This Week in Science #8

PARAGRAPH 1
This week in science we learned lots of new vocabulary words like dorsal. Dorsal means the back of the animal where ever the animal has a spine.We also learned the word ventral which means the front view of something well its just the front of a animal.Also the word proximal means the distance between two things like your shoulder and fingers.We also learned about distal which mean the location of a body part like where the heart is for the craw fish.The environment craw fish lived in was a smelly wet area cause  when we took it apart it was one stinky craw fish. The craw fish had lots of features like orange guts, big claws, and a very weird mouth. The craw fish adapted tot there environment because they can walk and also go in water they have gills to prove that.
    
PARAGRAPH 2
My aha moments were when i found the craw fish lungs. It took me for ever to find them thanks to Jamie i found them. The craw fish cuts were orange. ewww. I had a aha moment when i realized that the craw fish didn't smell like craw fish. that was the biggest aha moment for me. I had a aha moment when i found out that i should of done the cricket. The craw fish reminded me of a lobster. The craw fish is a smaller version.Plus more people eat lobster than craw fish. I also noticed that the craw fish has a stomach that is almost up to there mouth.
