Negative Feedback Loop

Negative feedback is not always a bad thing. This does mean that we as humans have done something wrong to harm the environment and organisms in it. However, it lets us see what we did wrong and how we can fix those problems. For example, water pollution is something that happens everywhere by humans. People will dump poisons and other harmful things in rivers and lakes. We see the effect of this on the animals in those environment. Those animals will either die off or they will infect humans who eat those animals. As humans we will help stop polluting the water systems so the whole environment can enjoy clean water. 

An example of Negative Feedback Loop:

Sun Flower Plant

My sun flower plant took about five to six days to see my first sprouts. I put three seeds in the soil in my cup and  successfully had three sprouts. I kept them outside all day in a lot of sun and watered them once a day. At about three weeks I noticed that they began to grow at a more rapid pace. They went from sprouts to about two inches tall and had about two leaves. I was excited to see there progress. However, at about five weeks one of the plants began to turn yellow and later died. Two plants remained. At about seven weeks, the two plants gained a lot height and I had to transfer them to a bigger cup. After this week, the cold weather got to them because I accidentally left them outside for a weekend.
 

My Happy Place

My happy place that I visit often is probably St. Simons Island, Ga. I have been going to this beach ever since I was around three years old. This is also the first place that I have ever been fishing and sailing. My family and I have always visited this special place every July 4th. I enjoyed going to the pier early in the morning and go fishing with my dad and brother. We would never catch anything to keep, but I liked seeing everyone else their catching sharks and sting rays. This place will always make me happy no matter what. When I have a bad day I think of St. Simons and how special that place is to me.

  

Bio diesel Lab Report

Our the lab the other week we ventured to Dr. Rood's science lab at Mercer Law School. At this lab we got to look around at all the really interesting things. The main reason we were there was to make bio diesel. The benefits from making bio diesel is: it provides a high energy return and displaces imported petroleum, and it reduces greenhouse gas emissions. You can actually make bio diesel at your house! In order to make bio diesel you can use methanol and mix it with vegetable oil. Also other natural gas are helping us not use up all the petroleum. The natural gas can also help with electricity related items as well.

Mitochondrial Eve

Mitochondrial eve is the woman who was the first human on the earth. The original place where she lived was in northeast Africa and then they moved on towards India, Asia, Europe, Australia, North America, and South America. This also means that we are all related because we all come from the same ancestors. However, we all do not look a like because of melanin. Skin color is the main reason why we do not look a like because we have different skin color to adapt to our environment. For example someone in Brazil is going to have darker skin than someone who is from Europe. This is because people in Brazil are outside in the sun more than those in Europe. Thus, they have darker skin color in order to keep them from getting sun burned or skin cancer.

Amphixous

Amphixous are known to be the first ever vertebrates in the world. They are usually found in sand near the tropical seas as well. They are also harvested for people to eat in Asia and for animals to eat them as well. They are a big factor in the sense of evolution and how they were formed millions of years ago. They grow to be about five centimeters long and have a clear, fish like body that has can swim. It makes us wonder how they survive in their environment because they are not very well adapted to where they live.

Macon Dog Park Lab Report

This past week we ventured out to the Macon dog park located near Tattnall Square Park. Dog parks are good for the community because it not only lets dogs interact, but also the dog owners can come together as well. This  was the first dog park that I have ever been to and I really enjoyed it. However, we were not there to just observe dogs playing. The main reason we did this lab was to test the creek water that ran through the middle of the park. We were testing this water in order to see if lead was polluting this creek. This creek water was formed by humans and the main source is from storm water drains. Lead is a major pollutant that can poison dogs and humans.
