Dissect frogs.
We just dissected frogs (Well, in our case, toads. Sir Dizon didn't want us to bring frogs because they jump. The toads were poisonous but you could just wash it off, and we were wearing gloves anyway) last Tuesday. Of course everyone was all excited and grossed out at the same time. I guess it was everybody's first time to murder a toad and play with its organs.
How to a annihilate a frog or toad
1. Catch a live frog or toad, place it in a Stick-O jar with holes on the cover and a little amount of water for the frog or toad. (In our case, we bought it :P)
2. Clean the frog or toad with water.
3. Paralyze the frog or toad via pithing.A sharp needle of a diameter appropriate to the size of the animal is quickly inserted in a cranial direction through the foramen magnum and is rotated in a manner to crush the brain bilaterally. The needle is then inserted in a caudal direction at the same point of entry and rotated to destroy the spinal cord.
4. Pin the frog or toad on the dissecting tray thingy.
5. Start opening the skin. Detach it first from the flesh thingy using the spatula. This removes the membrane that binds them together. (This part was fun, although I did feel the pain of the toad)
6. Cut the flesh. No need to explain, neh? Just be careful, you shouldn't cut the blood vessels unless you want it to be bloody.
7. Explore!
8. Throw frog or toad away and clean, sanitize, clean, and clean some more.

Our poor toad, Mr. Robert, passed away
a few seconds after we cut off his heart.
We will never forget him.
