Separating the Mixture

1. The first step that I did in this lab was take out the parts of metal.
2. I took out the large marble looking rock, out of the cup.
3. Then, I took out the two toothpicks.
4. I took out the rocks, separating the extra metal pieces from the rocks.
5. I took out the water and put it through the funnel on top of paper and put it in the graduated beaker.
6. After that, I put the beaker on the heat plate, and put it to a boil.
7. While emptying the rest of the cup out, I separated the rest of the objects into their own little group.
8. When the water was done boiling, it ending up as just plain salt.
9. In the end, there was seven objects in the cup for the heterogeneous mixture, metal, sand, rocks, one big marble type rock, water, salt, and the toothpicks.

Frog Disection

       The frog dissection on Tuesday and Wednesday was both informative and unlike anything I have ever seen before. This lab was actually easy due to the packet I received, it showed all the instructions and where and how to cut the frog. We learned about all the organs, what they did and how they worked. Although the frogs did smell horrendous, it was bearable. What we did in this lab was the following: we made a small incision, cut the first layer of skin, make another incision and cut the muscle, then finally look through all the organs. To me, this was a new experience and as stated before, unlike anything I've seen before. I've seen CSI, Law and Order, and NCIS, but only I've seen the 'fake' insides in the human body. I didn't realize what differences and similarities in the frog and human. Finally, I have learned so much from this lab.

As seen in class, I found the website that does virtual dissections. The link to the website is listed below.

The Digestive System Lab

      Both today and yesterdays lab was focused on the digestive system, in the stomach. What occurred in this lab was the digestion of cut/cubed eggs in a test tube either with nothing, pepsin, pepsin and hydrochloric acid, or just hydrochloric acid. What happened over  the coarse of the day was, the test tube with just eggs stayed the same color and size, the tube with the eggs and pepsin changed a little by, the eggs moving towards the bottom with the pepsin. The test tube with both pepsin and hydrochloric acid changed a lot. This was by the eggs and pepsin mixed together at the bottom and formed a clump which looked as if there was just sugar and water together. The last tube with hydrochloric acid changed somewhat, due to the acid; it changed by the eggs forming together and some parts of the egg would come off. What i learned/witnessed today and yesterday was, that the stomach has both a lot of muscles to help move food along and, the acid in the stomach is very powerful. This is because, in order for food to move into the small intestine and large intestine it needs the help. Also, the acid is very powerful because every three days the stomach lining 'rips' off and grows back because of the powerful acid almost burning complete holes in the stomach. Thus, leading me to conclude what I have learned throughout this lab. 

Todays Lab, October 11, 2011

      Today's lab was not a success. This is because, I believe the baggie, which contained both water and starch, was too thick for the liquid to seep into the baggie. Even though this lab was not a success, I've learned how this lab didn't work, if it did work, the starch would have turned purple. If all labs did not have trial and error, life would be a lot easier, but it is also good to have errors to see which chemicals go with other chemicals without them blowing up or creating a pandemic. Also, tomorrow I think we will redoing the lab, since the lab didn't work today. In the future I think we should test it to make sure everything works out the way we planned it. In conclusion, I do believe we should test the labs for a success.

The First Cloned Animal Ever!

      In 2001, the first ever animal was cloned. The name of this cute and adorable kitten is "CC" short for "Carbon Copy.” In 2006, she gave birth to a healthy litter of three. Many scientists have tried cloning dogs, yet in 2003, they were successful with the "Snuppy," the world’s first cloned canine. They use the cloned dogs to sniff out explosives, drugs and other materials. After the success with "CC" and "Snupy", they created Dolly the sheep, who died at the age of six. Once scientists studied this, they proved the fact that it had nothing to do with cloning Dolly. The cloning animals all listed here have a life spand of about twelve years.

Angry Bird Attacks Reconized Face!

While Won Young Lee was researching the Magpies, the bird took a dive-bomb onto Lee's face. Lee has worked with these birds before; installing cameras in the nest's. During the attack, Lee was already counting the amount of egg's per nest. Lee is a student at at Seoul National University, stating that

"I remember when a magpie came down from a nest tree scolding at me, I was with a second researcher at that time, and I tried to fool the magpie by giving my cap to the other person. But this did not work! When I moved away the bird followed me rather than the fellow observer wearing my cap." From my perspective I would have done the same thing that Lee did, if I were in his situation. I also for one would not want to be attacked by the magpie, because to me the beak looks not only sharp, but very long.

Donald Trump, Serious?

      After reading the article about Donald Trump's presidential campaign, I have realized that Trump will not be running for president. "After considerable deliberation and reflection, I have decided not to pursue the office of the presidency, this decision does not come easily or without regret." Trump said on last Monday. At a tea party, in Boca Raton, Florida, Trump dropped the F-bomb to Obama. Trump thought before of running for president, in 1998, 2000, and 2004 stating that he "might", "considering it" and "very serious". Trump, was most "flirty" with the government, when it comes to politics. For more than twenty years, Trump has been considering a presidential campaign. Finally, Trump was not serious about the presidential campaign, and will not be running for president.
