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.

Darwin's Dilemma Lab Report

The last lab we had was when we watched the movie Darwin's Dilemma. This movie was about studying the animal fossil records and how complex they are. This was also known as the Cambrian Explosion because he was able to find genetics of different species and how they were able to survive the places they lived. Also how unique this new species the Cambrian was in the environment. From its shell and skeleton were so complex and thought that evolution had caused this specie to evolve in the world.

Hitchiti Forest Lab Report

This past week we went to the Hitchiti Experimental Forest located near Jarrell Plantation. We had a long hike ahead of us, but it was a lot of fun! During the hike we identified trees, plants, and even rocks. The most interesting leaves we found we of the Sassafrass tree. These leaves were shaped of a glove, a hand, and a regular looking leaf. Another interesting plant we discovered was Wild Ginger. This plant was interesting because  of the wild ginger smell whenever you cut the leaf open. We also saw some different kinds of moss growing big limestone rocks near the river. Some of these mosses were sponge-like and a light green color. We also enjoyed walking on the rocks through the creek and by the Ocmulgee River!

Jackson Springs Lab Report

Our adventure through Jackson Springs park was a good historical and scientific lesson. At first we went to this city creek that ran through the whole park where we found many rocks. The samples of rocks taken were: granite, feldspar, mica, and quartz. The geological findings were really exciting! From there we discussed about the history of the neighborhood named Baconsfield, and how it has changed throughout the years. Fort HIll used to be back in 50's where the middle class people would live. However, now that has changed by middle class people moved to the neighborhood near Jackson Springs and the lower class people are more dominate in the Fort HIll area. After this history lesson of that part of Macon, we then ventured on to the Ocmulgee River which was a good time as well.


Ocmulgee Indian Mounds Lab Report

The Ocmulgee Indian Mounds that we visited for our lab was a great experience. Even though I went on field trips to this site when I was younger, I was able to enjoy the time spent there. Our walks on the trail were awesome because we identified different trees and sedimentary as well. My favorite part of our lab was when we all went to the top of the bigger temple. These temples were burial grounds for those Native Americans that died there. They built these temples or mounds in order to keep those bodies that died to be sacred and secure from others.

Lake Jackson

The most interesting lake to me is Jackson lake. I have grown up going to this lake with my good friends doing many fun activities on the water. The fun activities we do are; water skiing, tubing, wake boarding, bridge jumping, and even fishing. The Ocmulgee River starts at this lake and goes through Macon. A good thing about this lake is it has clear water which is another reason why I like going there. The water sports are what most people from around Georgia go to this lake for. Also the fishing is great during spring through fall seasons as well.

Blood Sugar Response

The more sugar one intakes during a certain period of time will effect how the human body will respond. For example if you drink a sprite or eat a candy bar it will take around fifteen  to twenty  minutes for your blood sugar to go sky high. This is caused by the amount of insulin produced in your body. The liver turns the sugar into fat and then the caffeine is absorbed causing your blood pressure to rise, and the liver pumps more sugar into your bloodstream. Your body does its best to burn the rest of the sugar in your system as well. It will take you about forty to forty-five minutes to come back down to your normal blood sugar rate. 

Lab Report #4

My Favorite type of soil is the Histosol. I find this soil the most interesting because it is made up of organic compounds. These compounds are made from decomposed animals and plants. This is also where organic carbon can be found as well. The longer and more accumulations of decomposed matter in this soil is when coal will begin to form. Most histosols are found in Canada, Scandanavia, New Guinea, and even the swamps of Florida.
The 12 types of soil are found at this website https://www.soils.org/about-soils/soil-types

Community Gardens are becoming a popular activity for people in urban areas. These gardens are tend to by people in the community, and they take part to help promote a food system. The community garden we went to is a non profit organization gardened by people from Mercer and other neighbors. This is a great way for people to come together and help the community. http://www.maconroots.org/

ENB150 lab report

!. Choropleth map- people use this map because it shows a measurement changes from one area to another in one region.
 2. Proportional Symbol map- people use this map because it uses symbols to show population. A bigger symbol means a bigger population of people using something.
3. Dot Density map- People use this map because it uses small dots to identify how densely populated an area can be.

ENB150 interesting animal

The most interesting animal that I like is the jaguar. The jaguar is the third largest feline behind the tiger and lion. This big cat lives in the southern United States, Mexico, most of Central America, and South America. Most jaguars are found in forested and open areas. Like tigers, the Jaguars are known to swim in rivers. They stalk for their prey and are at the top of the food chain. They are an important part of the ecosystem as well. The jaguar has become a near threatened species because of destruction of their habitat by humans.
