Separating Mixtures Procedure

Step 1: Take out all substances other than water with a spoon, and put them to the side.
Step 2: Pour the water into the beaker.
Step 3: Use the magnet to take out the iron from the other substances. 
Step 5: Put the beaker with water onto the hot plate and plug it in into an outlet.
Step 6: After the water starts to boil you should see the secret ingredient(salt). 
Step 7: Carefully, take your tongs and pick up the hot beaker from the top and put it on the table. Make sure the table is meant of science. The hot beaker can burn plastic.
Step 8: After the liquid cools down, pour it into the graduated cylinder.
Step 9: Put the filter paper on the funnel and pour the water through it into the beaker.
Step 10: By now, you should be able to see the salt for sure.
Step 11: Record all your steps, so that you can share them with your group if they missed any.
Step 12: Clean up! Make sure it's as clean for the next group as it was for you. Try not to break anything!

Extra Credit #3

“Education is the key to unlock the golden door of freedom”

        The quote above can mean many things. To me it means if you get proper education, you will get all the freedom in the world because you know whats going on and what you need. In life, you are nothing without education. If you are not educated people can use you. Also, when you go shopping and if you get the wrong change back, you will not realize it. Education is the key to success. You will make the money you do with education you have. This is what the quote means to me.

Frog Dissection


Yesterday, In class I dissected a female frog. This showed us how the inside of our human body looks. I learned that if the human and the frog have the same part, they have the same function. For example, the stomach in both of our bodies has the same function. This function is the break down food in the process of digestion. The liver produces bile in both of our bodies. Although, the stench was gross, I learned a handful. Also, because we got a female frog, we had to remove the eggs. I thought that the eggs would be in little clumps in certain areas, but they were through out the entire frog! It took a while to take out, but you need to in order to see all the other organs because the eggs are covering them. I thought the liver was really cool. It was three different sections. I thought it would be just one. My group also opened the mouth and took the tongue out! I imagined all frogs having the long tongue to catch flies. This frog had a human shaped tongue in a smaller size. I know that the frogs food had digested or the frog had not eaten any food because when we cut open the stomach it was empty. I actually wanted something to be in the stomach so that I could see what the frog we dissected liked to eat. I feel that this frog dissecting lab was very helpful. Now I get a better understanding of what the inside of my body looks like. All in all, I would love to dissect another frog to see if there are any differences in it.

Also, while doing this lab, my emotions about the frog changed several times. When we first got the frog, I thought I was going to throw up. The stench of the frog was so strong. When we cut open the frog, it was filled with eggs. It looked gross because it looked like there were little bugs in the frog. That part scared me. I disgusted when we had to take the eggs out. They were gewy and stuck to each other. They were all over the frog. I thought the liver was really cool. It reminded me of a shamrock because of the three parts. I imagined the heart to be much bigger than it was. That surprised me. I thought it would be as big as the stomach was. Speaking of stomach, there was nothing in our frogs stomach when we opened it. This dissapointed me. In conclusion, this lab was really cool and fun. It's a great way to learn about the human body! I would not mind dissecting another animal.

As the Stomach Churns Paragraph

       In class, we worked on a lab which taught us how our stomach worked. We labeled four different tubes from A-D on day one. We put pepsin, a meat tenderizer, and hydrochloric acid in the test tubes. On day two, we observed the test tubes to see the changes that happened over-night. We took a straw and poked each test tube with it and then swiped the straw on litmus to see what color the paper turned. For test tubes for two of the four test tubes, nothing changed. For the other two test tubes the products in the test tubes changed the litmus to a pink color. This is because these were the test tubes that had hydrochloric acid in them. This lab shows how our stomach works. The digestive system is very slow. It is able to break down food we eat with enzymes and acids. This is what we have been learning for the past two days in the lab.

Chicken Wing Blog

         In science class, we did an experiment by dissecting a chicken wing. We saw how the wing stretches out when a muscle is pulled. We saw the fats in the chicken. The fats keep the chicken warm when its cold. While the chicken was dissected we saw the cartilage, bone marrow and the ligament. Chickens have many things in common with us. We both have muscle, fat, bone marrow and many other things. We barely have anything not in common. Chickens have wings, and we don't. The dissection did gross  me out  a little but I learned many things in this lab.

Diffusion Lab paragraph

     The diffusion lab was very interesting. Our group learned many new things. The group found a few difficulties to the lab. The classes first and second try was unsuccessful. The third try worked better. The purpose of this lab was to  observe the diffusion, which is the process by which molecules move from an area of higher concentration. My group found that the substance was isotonic. This means, its equal in the solution combination. We also, diluted the cornstarch with water and made the liquid thinner so that it was a water consistency. Then the group put the cornstarch in with the iodine. The substance became purple. The molecules were very concentrated in the baggie. they all combined and made purple water. The word concentrated is a place where lots of molecules are impacted. Basically, this means that the indicator changed color to purple. The iodine was hyper tonic, which means there was more iodine than cornstarch and the water mixture, which makes the water and cornstarch hypo tonic, which is less than. This was the purpose of the Diffusion Lab.
     Next, in this lab water, iodine, and cornstarch were implied. The water was used to put in the iodine. The iodine was used to put in the water to change the color of the cornstarch. The cornstarch was used to show what happened to the iodine and the cornstarch. The cornstarch turned purple and the water became normal color, clear. The water became a yellow orange color. the cornstarch and water mixture became a purple color. In the teachers lab, the iodine had all gone into the cornstarch and water mixture. The water then was normal, clear. This was the analyzes of the Diffusion Lab.
      Then, this lab has made a few connections to life. One connection is that when you mix Kool-Aid into water, the molecules mix together freely. This is just like when the water, cornstarch and the iodine was mixed together. Another example is when sweat evaporates into the skin and the water diffuses into the atmosphere. Next, oxygen diffuses from the air sacs in your lungs into your blood capillary. Lastly, when you bake and when the aroma hits your nose the molecules have gone into the air. This is how you  can smell the food your baking. These are some life connections. This is what the Diffusion Lab was.
