Soil Quality Tests For Classroom Use, Kathleen Thompson

Theses/Capstones/Creative Projects

Soil analysis can traditionally be carried out by professional labs for a certain price, but this price adds up quickly when running many samples—as is often the case when pursuing a research question. Price is of particular concern in the classroom setting, where funding for student research can be limited.

This project examines several commercially produced soil test kits that are capable of testing a soil’s pH, nitrogen, phosphorus, and potassium; parameters which are of primary importance for plant growth. The project provides an overview of each kit’s contents and properties, a scientific assessment of their precision and accuracy, and …

What Is The Most Threatening Disaster To The Continental United States?, Aaron Spomer, Elijah Kaufman, Julisa Prieto-Garcia, Brooke Aschwanden

UNO Student Research and Creative Activity Fair

Our goal for our project is to fully understand which natural disaster is the most destructive to the United States. We have chosen to compare hurricanes, floods, tornadoes, wildfires, earthquakes, and nor’easters. We have researched the cost of the total damage and repair, how the warning systems have improved over time, the death tolls from each, and also the frequency at which each one occurs. Each group member will research a different disaster impact, and the data will create a comprehensive view of the level of devastation each disaster has. We collected data all the way from the early 1900s …
