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.

Lab
During the Diffusion Lab, I noticed many things and had a few questions as well. A question I have is, why did the iodine make the cornstarch a light purple color? What caused it? Something I learned during this lab is, that we were unsuccessful on our first try, so what was the cause of that? When we did it a second time, it worked better. These were some of the things I wondered and discovered during the Diffusion Lab.

Chemical Suspected in Cancer Is in Baby Products
Over thirty years after chemical flame retardants were removed from children's pajamas because they were suspected of being carcinogens. More research shows that a chemical is prevalent in baby products that have polyurethane foam including nursing pillows, car seats and highchairs. The research does not tell if the chemical has been absorbed by children. But it does tell that researchers suggest that infants who use the products have higher exposure to the chemical than the government recommends. They found chlorinated Tris, in children’s pajamas in the 1970s. Although, it was not banned at the time. The Consumer Product Safety Commission now says that it “may pose a significant health risk to consumers.” Researchers found that 1/3 of baby products were tested and contained chlorinated Tris. Eighty of the products had chemical flame retardants of some kind. Some are considered toxic, but legal to use. Among the products examined were changing table pads, sleep positioners, portable mattresses, baby carriers, rocking chairs and highchairs. Fourteen products had the flame retardant TCEP, which the State of California describes as a cancer. It got banned in many countries, but not the United States but some states including New York. Overall toxic chemicals are in our homes at high levels; and right now, people don’t know much about it. California standard, passed in 1975, requires that polyurethane foam in upholstered furniture be able to withstand an open flame for 12 seconds without catching fire. It's becoming much better.

Black Bears
The study has found that black bears have only killed sixty-three (63) people over the United States through Canada in the past 109 years. Bears that kill are not always mothers who are trying to save their cubs. Most of the time bears attack you because there looking for a prey to eat. Ninety-two percent of those bears are male. However, when a mother bear feels threatened the will get aggressive. They make loud sounds and they they swat the ground with their paws and run at people. They try to make you think that they will eat you but they usually stop. It tests you out as a possible prey item. It follows you like a lion. Eighty-six percent of attacks occurred 1960-2009. Not as many bears are there today to come and attack you.

Toothpick Fish Analysys
Toothpick Fish Analysys
I took and analyzed data for the four generations. In the first generation, I had eight green fish, one red fish and three orange fish. In the second generation, I had seven green fish, one red fish, one yellow fish and three orange fish. In the third generation, I had six green fish, one red fish, one yellow fish and three orange fish. In the fourth generation, where there was the environmental disaster I had seven green fish, one red fish and three orange fish. The population changed bacause in the environment that these fish live in, it is green where the green fish can easlily camouflage. The red and orange fish hide very well in the colors of algae and seaweed. Sadly, the yellow fish can be seen by their predetors and are eaten. The fish that are dead get put into the morgue. Because these fish got eaten the population changed and the population of fish decreased.
The environmenmental impact of the fish pond is that these fish are being eaten! Now the fish population has decreased. This means that there would be less offsprings. Also, after the environmental disaster the green fish also got eaten. the algae and seaweed died. Because the fish food died there is a possibility that some of the other colored fish could have died from starvation. If some fish had offsprings the offsprings could have also died because they couldn't camouflage or from starvation. This was a huge environmental impact. If this project were changed my predection would be take all information independantly.Instead of losing the fish we could increase the amount of fish we have. This is how I think we could change the Toothpick Fish project.
