College Park Scolars Program: Earth, Life and Time
Hi, I am Alex Rumbaugh. I am a Student at UMCP.
I graduated from High School in 2004.
I grew up just down the road in Takoma Park, and I gradutated
from Montgomery Blair High School. I played on Blairs varsity
Baseball team. I've always been a terp fan my whole life, and
I'm also a fan of the Redskins and Orioles. In my liesure time, I
enjoy working out at the gym, listening to music, and throwing a
raquet ball off the walls in my dorm. I often check sports info at
ESPN.COM

Field Trip 1 Jug Bay Wetlands Sanctuary and Chesapeake Beach:
On October 23rd, I attended the field trip to the Jug Bay Wetlands
and the Chesapeake Beach. This gave me a chance to enjoy a hands-on
experience with nature and fossils. I was able to keep several of the
rocks and fossils from the beach. Some of these included igneous rocks,
and shark teeth, ect. This field trip gave me a chance to intetact
with the outdoors, and interact with Nature. The Jug Bay Wetland Santuaty
is located in Anne Arundel County and contains over 8 miles of trails
where one can explore the habbitat. At the Chesapeake Beach, the tide
varies, causing the rocks on the beach to slowly wash away. This provided us
with a chance to explore the igneous and sedimentary rocks of the beach.
The Jug Bay Wetland is a home to a large array of floura and founa.

I was originally scheduled to go to Harpers Fairy, but that trip got cancelled.
I instead visited to National Museum of Natural History on April 10, 2005.
I visited all of the exhibits and selected two which I will write up.

A)
Brief Timeline: (Millions of years)
4600 – Solar System
3800 – Rocks
3500 – Fossils
1500 – Cells with Nuclei
600 – Fossils of multi-celled animals
The primary environmental change was the Oxygen Reduction. This is
where water vapor reacted with sunlight to yield a large enough of oxygen
to breed multi cell life. Before this occurrence, there was still evidence
of life, known as Stromatolites. They are algae and bacteria and they indicate
that there were organisms capable of photosynthesis. These life forms are
estimated to be 800-2000 million years old. This shows that not all forms of life
require oxygen.

E)
This section is dedicated to the evolution of mammals, horses to be more specific.
The three main types of horses in chronological order are: Hyracotherium, Mecohippus,
and Equus. Much of the evolution can be explained by three major climate cooling
periods which were 50, 38, and 30 million years ago. 50 million years ago, there
existed the Hyracotherium, also known as an Eohippus. 38 million years ago, during
the second cooling period, the horses started to evolve; their teeth became more
durable and had more complex patterns. The horse’s teeth continued to get stronger
and more durable as time progressed. Some other evolutionary traits were their eye
sockets moving behind their mouth and they also had a longer stride which caused
them to run faster. This evolution relates to the common horse today.

Title: Volunteering as an Emergency Medical Technician
Description: He performed activities such as splitting broken bones, giving oxygen
to patients, etc. This re-enforced the fact that he wanted to be a doctor.

Description: He interviewed Dr. John Hillman and went over all of the stuff that he
has done. He did stuff like reviving works from Archimedes, reviving US flags and
stuff like that.
