Materials and Methods
- Magnifying glass
Step 2: Wash the rat in the sink to get of chemical smell, gently dry off and put back on tray, belly up.
Step 3: Examine the outside parts of the rat, and write down the explanations of what each of these pieces provides to the rat.
Step 4: Determine its gender.
Step 5: Name your rat something you'll remember (for example :Billy Bob)
Step 6: The writer should then put the name on the "body bag"
Step 7: On your paper the teacher provided, match the internal organs to their job, should be fairly simple.
Step 8: Surgeon 1&2 should work together to open the jaw with scissors to make sure for a wide finish.
Step 9: By opening the jaw, the surgeons shall now be able to notice a difference between the incisors and the molars, and the hard palate and soft palate.
Step 10: If need be, pin down the feet and arms.
Step 11: If the jaw is open enough, you should be able to use forceps and loosen the muscle from the skin.
Step 12: Cut the rats skin but follow the PowerPoint you should find on netschool. Be sure to not cut too far deep to were you break into the muscle.
Step 13: Once the skin is cut, pull it back or cut it off, and continue into cutting into the muscle.
Step 14: If need be, drain the excess juices inside of your Rat. (This is disgusting so get someone who has a strong stomach).
Step 15: The surgeons will then cut the rats tail off with forceps and the scalpel and look at the bones and muscles inside.
Step 16: You shall then follow to opening the muscles inside the throat, being careful to not cut into the trachea.
Step 17: Once you see where the trachea is, cut open the chest.
Step 18: Cut under the armpit and continue down the sides to expose the ribs. Be careful, if you break the ribs they will be extremely sharp and will cut you.
Step 19: Next you will then explain all of the functions of each of the organs in the rat on the sheet the teacher provided for your group.
Step 20: You will then take all the organs out that are on the laminated organ sheet, and place them on there. See if you can stretch the intestines out and measure them.
