Traffic Lab

For this lab I watched the vehicles that passed Mercer Village Jittery Joes over a 10 minute span.  What noticed is that most of the drivers were actually driving instead of being on their phones.

Mitochondrial Eve

Scientist have come up with a theory of evolution that may possibly link all human beings together genetically. The theory suggests that there may have once existed a maternal ancestor whose genetic DNA is shared by all human beings. This maternal ancestor has come to be called our Mitochondrial Eve. Human beings, none to be excluded, receive their mitochondrial DNA only from their mothers. Genetically, nearly 100% (99.9%) of all mankind’s mitochondrial DNA is identical. For scientists, this is a critical characteristic that can be used to backtrack in time and locate where our Mitochondrial Eve may have resided. In this way, Mitochondrial DNA allows us to date back 65 million years of history. As seen in the geographic diagram below, it is suggested that our Mitochondrial Eve may have been from the Northeastern Region of Africa.

Shrubs and Trees

Weeping Willow:

Known for larger size and drooping branches and leaves.  Found in moist soils and cold temperate regions of the Northern Hemisphere.



Crepe Myrtle:

Known for their colorful and long lasting flowers which occur in the summer months.Most species of Lagerstroemiahave sinewy, fluted stems and branches with a mottled appearance that arises from having bark that sheds throughout the year.

Loblolly Pine:

A pine that is native to the Southeastern United States. It is the second most common species of tree in the United States. It is also the most commercially transported tree in the United States.

Mountain Fetterbush:

A large shrub with leathery leaves that shed in Autumn or wither to brown until spring.  Native of the east coast in USA.

Dendrochronology Lab

The purpose of this lab is to identify the age of a tree by determining the number of rings it has. In this lab, we will also determine the climate of the given region from which the tree examples came. The first part of the lab was to count the tree rings and determine how thick each of the rings were. The second part of the lab was to find the historical data for the temperature and precipitation of both Macon, Georgia and Palm Springs, California

Dendrochronology is the process of dating a tree based on the rings of the tree.  So from counting the tree rings I have guessed that the Elm Tree is 35 years old and the Pine Tree is about 65.

Maps

Choropleth Map
The shaded areas are the percentages of how many people are in the area.  This map makes it easier to see the difference from place to place.


Isopleth Map
Gives depth to a certain location.



Dot Density Map-
Uses dots to present and show the data, the more dots the more data.

Rock and Soil Identification

Igneous Rock- 

Rocks that form directly from magma.They are classified as basaltic or granite, and as intrusive or extrusive.



Sedimentary-

Form from sediments such as mud, sands, or gravels compressed by overlying sediments.  This formation takes a long time to occur so most of these rocks are usually fossils.



Metamorphic-

The combination of the two when they are put in high pressure and high temperature.



Soils-

Barometer Lab

A Barometer is an instrument used to measure air pressure.  The purpose of this lab is to learn about the measurements of barometric pressure.  The device below is what helped us find out the information of Macons atmosphere air pressure.

1 atm =760 mmHg

1.00 in = 2.54 cm
