Be brave, treat them scientifically.

Yesterday's biology lesson was all about rat dissection.  The rats we used were killed two weeks ago, being frozen and got defrosted on last Saturday.  My teacher dissected a pregnant rat and we found 15 foetus in her body.  I felt so sorry to those rats, but they sacrifice for education purposes.  So, treat them scientifically!  We respect them and didn't play around with their bodies. 

Before this, when I first entered the classroom, I saw the slideshow on the screen.  I was like Ohmygod when I knew that we need to dissect a rat.  lucky that it's not a frog.  



Although there was one piece of rubber between my body and the rat's body, I can still feel the coldness, hardness of the corpse.  I need to face the fear.  Okay, took a deep breath, one two three, and I cut through its outermost skin and finally reached the thin membrane.


Everything went smoothly after that, I worked with my team mates.  We looked at the respiratory, digestive and reproductive system.  Well, I had no idea where is the reproductive system, i mean, where are the organs?
