Description
STEM education stands for science, technology, engineering and mathematics, and is necessary for students to keep up with global competition in the changing job market, technological advancements and challenges of the future. However, American students are lacking STEM achievement at the state, national and global levels. To combat this lack of achievement I propose that STEM instruction should begin in preschool, be integrated into the curriculum and be inquiry based. To support this proposal I created a month-long physics unit for preschoolers in a Head Start classroom. Students investigated the affect of incline, friction and weight on the distance of a rolling object, while developing their pre-math, pre-literacy and social emotional skills.

Over the past few years, the issue of childhood trauma in the United States has become significant. A growing number of children are experiencing abuse, neglect, or some other form of maltreatment each year. Considering the stressful home lives of maltreated children, the one sure sanctuary is school. However, this idea requires teachers to be actively involved in identifying and caring for the children who need it most. Traumatic childhood experiences leave lasting scars on its victims, so it is helpful if teachers learn how to identify and support children who have lived through them. It is unfortunate that teachers will most likely encounter children throughout their career who have experienced horrendous things, but it is a reality. With this being said, teachers need to develop an understanding of what traumatized children live with, and learn how to address these issues with skilled sensitivity. Schools are not just a place where children learn how to read and write; they build the foundation for a successful life. This project was designed to provide teachers with a necessary resource for helping children who have suffered traumatic experiences. The methodology of this project began with interviews with organizations specializing in working with traumatized children such as Arizonans for Children, Free Arts for Abused Children, The Sojourner Center, and UMOM. The next step was a review of the current literature on the subject of childhood trauma. The findings have all been compiled into one, convenient document for teacher use and distribution. Upon completion of this document, an interactive video presentation will be made available through an online education website, so that distribution will be made simpler. Hopefully, teachers will share the information with people in their networks and create a chain reaction. The goal is to make it available to as many teachers as possible, so that more children will receive the support they need.

A look at the benefits of the integration of music in the classroom. This thesis focuses on how music supports brain development and how that affects the ways children learn the classroom. It also highlights how current teachers feel about integrating music in the classroom and the best practices used for integrating music. Lastly, this thesis contains strategies on how to integrate music in the classroom using the Common Core standards as well as personal compositions written using Common Core standards.

Description
In this project, we aim to fabricate PIN structure-like diodes for radiation detectors using Boron Nitride (BN). This fabrication is done by performing lithography and metal deposition processes on a Cubic Boron Nitride (cBN) of around 200 nm in thickness layer on top of a boron doped diamond substrate. The main goal is to create the most efficient and affordable alpha particle—and ideally neutron—detector in a radiation setting. Thus, making more accessible radiation detectors that can be more easily produced and disposed of, as well as minimizing the size of conventional detectors.

Description
In this project we are analyzing the diamond-titanium interface as it applies to diamond-based diode devices, including alpha particle, proton, and neutron detectors. This is done through the fabrication of an O-terminated B-doped diamond sample with a 20 Å Ti / 10 Å Pt overlayer which was then annealed and examined via X-ray photoelectron spectroscopy (XPS). It was discovered that after annealing the sample at temperatures ranging from 400 C - 900 C that TiC was not formed at any point during this experiment. Possible reasons for this include a lack of sufficient titanium in order to form TiC and over oxygenating the diamond surface before the metal was deposited.

Description
This paper begins with an introduction to the topics relevant to the research presented. Properties of diamond, diamond’s ability to be used in power electronics compared to other semiconducting materials, and a brief overview of field effect transistors are among the topics discussed. The remainder of the paper centers around research that has been conducted on seven diamond samples. Interface characterization was performed on two diamond samples, one with a high boron incorporation epitaxial layer and another with a low boron incorporation epitaxial layer. UPS He I analysis and UPS He II analysis were used to construct band alignments for the two samples, which revealed no significant differences between their measured properties. A Python program designed to optimize XPS loss peak and UPS He II graphical data analysis is also discussed in detail. Next, Hall effect measurements are examined. Hall effect measurements were carried out on seven diamond samples, two of which have high boron incorporation epitaxial layers, two of which have low boron incorporation epitaxial layers, one of which has a moderate boron incorporation epitaxial layer, and two of which have a phosphorus-doped epitaxial layer. Hall measurements of the boron-doped samples revealed no significant differences in measured parameters amongst the samples with varying boron incorporation epitaxial layers, with the exception of an expected difference in measured carrier concentration proportional to the amount of dopant incorporation in the layers. Some samples with boron-doped epitaxial layers produced measurements indicating n-type charge carriers, which is unexpected given the p-type charge carriers within these samples. The phosphorus-doped samples were unable to be measured due to overly high resistance following an oxygen termination step, and this effect was functionally reversed following hydrogen termination of the samples. It is hypothesized that Fermi pinning is responsible for this effect. The paper concludes with a summary of data discussed in previous sections and a suggested direction for future research on this topic.
