A hydrothermal vent is a place in earth's surface where geothermally heated water comes out. They are common around places where tectonic plates are moving apart from one another. Under the sea, these vents might form features called black smokers.
Holger Jannasch worked for Wood Hole Oceanographic Institution and helped study the deep sea. He along with his institution were the first to study the deep ocean floor. They were able to bring samples back from the ocean floor that allowed them to study the species.
Alvin was the submarine used by the institution to gain access to the ocean floor. It was the first of its kind and had a robotic arm that allowed for gathering of specimens on the floor. This allowed for new information to be obtained that could not be seen before.
Tube worms were one organism that lived on the ocean floor. They are worm like invertebrates that anchors its tail to an underwater surface and secretes around its body a mineral tube, into which it can withdraw its entire body.

Topographical and Digitizing Maps
We were assigned to pick a geographical spot and place three elevation lines on the spot. The red line represents an elevation of 900 ft. The yellow line represents an elevation of 1200 ft and the blue line represents an elevation of 1500 ft. This is just the basics of Topographics where people inspect different land plots.

Cemetary Demographics
We recently went to Riverside Cemetery where we looked at the age of people that died in 1918 during the Spanish Flue pandemic and also the age of people that died between 1960-1980. The goal was to see if there was any differences of lifespan of people in the two time periods. After looking at the data that we pulled, people that died in 1918 had a shorter life span compared to those that died between 1960-1980. Below is the data:

The Sun Across the Sky
We were asked to track to progress of the sun across the Earth's sky for our Environmental Science class. We used a fixed pole found in the parking lot and measured its shadow four different times in one day. With the length of the pole (39 3/4 in) and the length of the shadow, we were able to use the formula tangent=opposite/adjacent to find the angle in which the sun was in the sky. Also, with a compass we could tell what direction the sun was. Below is the data we collected:
10:15 AM- length of shadow was 54 inches, the angle of the sun was 74 degrees in the NE sky
1:30 PM- length of shadow was 24 1/4 inches, the angle of the sun was 164 degrees in the SE sky
3:15 PM- length of shadow was 32 inches, the angle of the sun was 124 degrees in the NW sky
5:00 PM- length of shadow was 77 inches, the angle of the sun was 52 degrees in the NW sky
10:15 AM- length of shadow was 54 inches, the angle of the sun was 74 degrees in the NE sky
1:30 PM- length of shadow was 24 1/4 inches, the angle of the sun was 164 degrees in the SE sky
3:15 PM- length of shadow was 32 inches, the angle of the sun was 124 degrees in the NW sky
5:00 PM- length of shadow was 77 inches, the angle of the sun was 52 degrees in the NW sky

Macon flood of '94
In 1994, Macon experienced a freak flood from the Okmulgee River. Much of downtown Macon was underwater and many businesses were damaged. Also the city drinking water factory was filled with clay causing the city to be without drinking water for 21 days. Why did this happen? This happened because just south of downtown there was a levi on one side and highway 16 on the other side. When the high river water reached south of the city, there was no room for it to spread out on either side. Therefore, the river bottled neck and sent the water spreading through downtown.

Sunflower
In our Environmental Science class, we were tasked to grow a sunflower in our dorm room. We were given the seed,dirt, and cup in order to grow the sunflower. Below is the tracked progress of my sunflower's growth:
February 7th- My sunflower begins to sprout
February 14th- Sunflower grows and reaches the top of the cup
February 24th- Sunflower is about three inches above the cup and has about five leaves on it

The Perfect Storm
In the movie The Perfect Storm, the lives of fisherman are examined. The dangers of being on the ocean are shown full force. The ocean is an unpredictable place and whether can change erratically. Some of the crew were thrown overboard due to big waves throwing the boat around. Another time a shark was accidentally brought aboard. However, the climax of the movie is when three different storm systems meet. The fishing boat is caught out in this weather but tries to push through it to get back home. The boat and crew were beaten and they think they are about home when a huge wave flips the boat and all of the crew dies. This movie shows that mother nature is nothing to mess with and can take human life very easily.
