Taphonomy of Herpetofauna
Screaming Neotoma Cave contains a rich deposit of mammals, birds, fish, and reptiles and amphibians. Images were taken using the scanning electron microscope at Northern Arizona University to illustrate important features on the bones, which demonstrate their taphonomic origins. The taphonomic analysis looked for and found the presence of acid etched and highly fragmented bone as well as well-preserved bone. These results determined how the fossils were deposited.

Digital Video Production
In this class, we produced and directed a documentary video. We learned how to work a camera, how to set up lights, how to edit, how to record sound, how to direct. We learned that it takes a lot of work to make a video. We learned what about the roles of the director, cameramen, editor, sound crew and special effects artists. Together all of these areas are needed to make the whole video work.

Human Interactions and Child Behavior
Children between the ages of two and five years of age are hyperactive or exhibit certain emotions and actions such as fear, happiness, and aggression. Young children were observed in a classroom setting and in the outdoor natural environment. This exploratory and qualitative study proved that children do become hyperactive when they are among other people.

Identification of Environmental Microorganisms
The purpose of this experiment is to identify an unknown microorganism from our everyday environment. A sample of an unknown microorganism was collected from the soil outside of the biology building. An isolation streak was performed many times to purify the microorganism. Staining techniques and biochemical tests were then performed. The microorganism was classified as Pseudomonas putida using the Bergey’s Manuel.

Steel Joint Design
This research project gave students the opportunity to design, analyze, and test steel butt joints. After testing the joint to failure, the experimental failure mode and load were compared with the predicted. It was found that although the predictions were correct on paper they weren’t perfect in application. With further testing of the materials and use of more accurate analysis techniques, the failure characteristics of the joints could be predicted with a superior degree of accuracy.

Many times students don’t know which college they should attend or even explore. Students also have difficulty realizing what kind of expenses that may arise during college as well as how to generate income and balance living and college expenses. Concerns such as these along with other real problems regarding college are answered with our research and a prepared analysis examining different ways to accomplish financing a higher education

Why Does the Water Rise?
When a jar was placed over a candle standing in a dish of water, the candle went out and the water rose. Why did the water rise? Tests manipulating the air pressure inside the jar were performed and provided empirical support for the differential air pressure hypothesis. Atomic molecular theory, kinetic theory, and the first law of thermodynamics provide further theoretical support for this hypothesis.

Growth Characteristics of Hybrid and Native Corn Varieties
In this study we identified types of corn varieties according to their growth characteristics. We found that the root length of native corn varieties grew greater than hybrid corn varieties. Also we found that the height of native corn varieties grew higher than hybrid corn varieties. The native corn varieties had more green colors of stems then red color of stems. The hybrid corn has more red roots than white roots.
