`Dendrochronology Lab

This tree, located in Macon Georgia, is roughly 70 years old. These are a few major events that took place during this trees lifespan. Some tree rings are less narrow than others. This is due to the amount of water the tree received each year. The less water the tree gets, the more the narrow the ring. 

Mapping Lab

Chloropleth Map: 















The map on the left is used to show the deaths in children under the age of 5 in Africa. The darker regions of maroon show the countries with the most deaths. The map on the right shows the population is Africa of those who are considered undernourished. Same as the map on the left, the dark regions demonstrate the areas with the most undernourished people.

Dot Density Map: 

This map show the population is each state in 1999. The dots are used to show the least and most populous states. The areas with the most dots and the most populated and the states with not as many dots are less populated.

Proportional Symbol Map: 

This map is used to show how populated the prisons are in the United States. The prisons that are not very populated have smaller circles, and the heavily populated prisons have larger circles.

Isarithmic Map: 

This map is used to show the average maximum air temperature in Ohio from 1971 to 2000. The blue shows lower temperature and the red shows high temperature.

Geology Lab

Igneous Rock: Granite

Granite rocks are formed by underground magma. They can be very old and date back to four billion years. Granite makes up a large portion of the Earth. Granite is made up of quartz, horns-blend, and feldspar. Other Igneous rocks include: pumice, basalt, and pyrite.

Metamorphic Rock: Marble

Heat and pressure cause marble to look the way it does. The rock is made of calcium carbonate which eventually turns into marble. Marble also cannot melt; it just simply changes its form. It is cut and often used for counter tops. Other examples of metamorphic rocks include: quartzite, anthracite, and slate.

Sedimentary Rock: Sandstone

There are various types of sandstone, which can even be used to build houses. Sandstone can form underwater on the ocean floor or on earth. Sandstone has multiple pores and can be used as a filter for water. Other sedimentary rocks include: siltstone, mudstone, and limestone.

Barometer Lab

The purpose of this lab is to measure air pressure using a balloon, a glass bowl, and a straw. Unfortunately, my straw barely showed any change, so this is the data from class.
