Separating A Mixture

1. Remove water from cup into filter on top of beaker, into the beaker.
2. Use spoon to scoop up the sand and put on tray. Then take beans from cup onto tray.
3. Put 1/4 of the water into flask.
4. Put beaker with water onto hot plate and heat (high).
5. Separate stick and bug from the cup onto the tray.
6. Use magnet to remove metal.
7. Remove beaker from hot plate, which should leave you with salt on the bottom.

The items you should be left with are: Water, beans, sticks, plastic bug, metal, sand, and salt.

Frog Dissection

In class, we dissected a frog named Wendall. First we cut off the skin then had to cut off the muscle under it, while breaking bones in the process. Since it was a female, we took out the eggs. We also looked at the heart which was a clear sac like organ. When the frog breathes, it expands like so:

Lower, was the liver, (when you cut it out, it smelled really bad.) Under the liver was a green little sac, which was the gall bladder. The liver creates bile and the gall bladder stores it. The stomach was next to the liver, and sometimes when you cut it, you can see the frogs last meal. Here is a diagram:

The frog's digestive system and respiratory system are a lot like a humans, with minor changes. When we cut the frog open, I almost immediately knew where everything was. The frogs skin and muscle was very thin, and if you looked on the inside, you can see the blood vessels. We also noticed that in the liver took up a great part of the frog, besides the eggs which also took up the other side. I wondered, why did the liver have to be so big? After we removed the liver and eggs, there wasn't much left. (Sorry about the way this section is spaced out, my computer is having issues.)

Frog Dissection

I also remember, how we thought the small intestine was the stomach, so we cut it up. We didn't get a chance to get a good look at the intestine though, so I don't really remember what it looks like. After we cut what was actually the stomach, there was nothing in there. It looked like a stitched up kidney bean.

Here is an online dissection game:

This game is online dissection in which you then have to identify the individual parts.

As The Stomach Churns Lab: Part 2: Day 2

In class, we looked at the test tubes from the day before. Test tube A, the egg white clumped and froze. When we put a stirrer in and put it on the Litmus paper, nothing happened. Test tube B, the egg white is gone and the pepsin went to the bottom. When we put it on the litmus paper, it was like sugar on paper, then slowly dissolved into the paper, making it wet. Test tube C, nothing happened to the solution and when we put some on the litmus paper, the paper turned pink. Test tube D, the pepsin went to the bottom, and the acid went to the top, and the egg white shrunk. When we put some on the litmus paper, the paper turned pink.

As The Stomach Churns Lab: Part 1: Day 1

In class, we did a lab using egg whites and hydrochloric acid. We had four test tubes, A. B, C and D.
Each test tube had three pieces of egg whites. We also put something different on top of the egg whites in each test tube. In test tube A, we put 10 mL of enzyme pepsin on top of the egg whites.  There was no immediate reaction in the egg white appearance. In test tube B, we put 5 mL of water, and 5 mL of pepsin. The egg whites started bubbling. In test tube C, we put 10 mL of hydrochloric acid. There was no immediate reaction. In test tube D, we put 5 mL of hydrochloric acid and 5 mL pepsin. The egg white was melting slowly. We then took stirrers then put them in each test tube then on to blue litmus paper. Test tube A solution, there was no immediate reaction. Test tube B solution, the litmus paper gets wet. Test tube C solution, the litmus paper turns pink, because when the hydrochloric acid touches blue litmus paper it turns pink. Test tube D solution, turns pink and for the same reason.

Chicken lab: Class Response

The chicken lab showed us how bones, blood vessels, and organs work. When Mrs. Rousseau pulled one muscle the other one relaxed. When one muscle contracts the other relaxes. Nervous tissue carries messages back and forth between the brain and every other part of your body. Mrs. Rousseau cut off the skin and then through some muscle and then blood came out because she cut through a blood vessel. Then Mrs. Rousseau cut the top of the bone off and then showed us the bone marrow.
