STAR Program Research Presentations

Planetary Protection is a discipline that aims to prevent forward biological contamination of other celestial bodies from Earth sources that might interfere with the search and detection of extraterrestrial life on interplanetary missions, such as Mars lander missions. Before any Mars mission with planetary protection bioburden requirements can be launched, the Planetary Protection team at JPL collects samples from the spacecraft and performs the NASA Standard Assay to detect any aerobic, mesophilic microorganisms. My primary objective for the summer was to take 60 isolates from the MER rovers and create long-term glycerol stocks, one working stock, and perform DNA extraction …

Jellyfish Identification And Quantification In The San Francisco Estuary, Amalia Borson, Lindsay L. Sullivan, Wim Kimmerer

STAR Program Research Presentations

As potential predators and competitors of plankton-eating fish, jellyfish have the potential to negatively impact fish populations. Jellyfish were collected weekly with plankton tows from the RombergTiburonCenterpier in Tiburon, CA. Since some jellyfish were too small to identify, one tow was collected and preserved to record abundances, and a second tow was collected to rear jellyfish until distinguishing characteristics were visible enough for identification. Jellyfish in the preserved tows were then identified, measured, and counted, and their abundance (number m^-3) was calculated. Jellyfish from the second tows were reared in plastic buckets that were lightly bubbled using aquarium …

The Standard New Astronomy Cryostat For Sofia: A Design For Cryogen-Free Infrared Astronomy, Carey F. Scott, Jeffrey Van Cleve, Eric Burgh, Earl T. Daley, Ali Kashani, Zaheer Ali

STAR Program Research Presentations

Astronomy at infrared wavelengths requires optical instruments that operate at low temperatures, which is typically done using liquid cryogens such as nitrogen and helium. These cryogens are costly and limit the operational time of the science instrument. The Standard New Astronomy Cryostat for SOFIA (SNACS) will provide a design for a helium cryocooler-cooled cryostat that meets the stringent airworthiness requirements of the Stratospheric Observatory for Infrared Astronomy (SOFIA) and can be used by future instrument builders to reduce the cost and risk of their instrument design and development. The SNACS dewar will provide approximately 3.4 x 10^-1 cubic meters …

Detection Of Salmonella Enterica, Escherichia Coli O157 And Listeria Monocytogenes Through Bead Based Magpix® Fluidics, Karamveer Singh, Francisco Fernandez, Sonam Sahni, Alejandro Calderón-Urrea

STAR Program Research Presentations

The research is testing the limits of detection and multiplexing with the use of three pathogens with the machine created from Luminex called Magpix. The pathogens are Salmonella enterica, Listeria monocytogenes, and Escherichia Coli O157. The gene that is being focused on for each pathogen is invA for Salmonella, hlyA for listeria, and hlyA for Escherichia Coli. In this research, we started with prepared probes that were attached to the magnetic microsphere beads. Then we extracted and amplify the DNA. Furthermore, the probes were combined to the amplified DNA and used this in Magpix which gave a corresponding MFI value.

Juxtaposing Nasa’S Aeronet Aod With Carb Pm Data Over The San Joaquin Valley To Facilitate Multi-Angle Imaging Spectroradiometer (Misr) Pm Pollution Research, John Kanemoto

STAR Program Research Presentations

Airborne particulate matter (PM) has been shown to increase the risk for asthma, chronic bronchitis, cardiopulmonary complications, and respiratory cell membrane damage/infection/leakage. PM levels are currently analyzed from two perspectives: stationary land-based monitoring (LBM) sites and total Aerosol Optical Depth (AOD) atmospheric column measurements. Both perspectives often leave miles of space between measuring locations and will have a continually increasing cost from introducing/maintaining sites. The Multi-angle Imaging SpectroRadiometer (MISR) satellite team hopes to begin investigating/archiving PM levels comprehensively via inputting MISR AOD measurements into a function/model which predicts the amount of ground level PM.

In the future, multivariable spatial correlations …

Slic: Family Science Backpacks For Preschoolers, Lorin Nevius

Psychology and Child Development

In this senior project, I reviewed existing literature regarding science instruction in preschool classrooms, young children’s capabilities and interest in learning science, what science is happening at home, as well as preschool teachers’ feelings toward teaching science. I explored the possibility of bridging the gap between the school and home environment by using a prepared informal learning tool that students could take home and complete with their family.

During the years children are in preschool, they are forming their understandings of the world around them (French, 2004; Nayfield, Brenneman & Gelman, 2011; Eshach & Fried, 2005). In developing these understandings, …

Benefits Of Pre-Lecture Assignments And Inquisition Based Learning In Comparison To Traditional Lecture Modes In Science Education, Lance Toppen

Biological Sciences

Experiment was an assessment of the efficacy of two different teaching styles: traditional lecturing and a question based approach. In a traditional lecture class students frequently come to class with little or no previous exposure to the lecture topic. This may limit comprehension, retention, and the development of critical thinking skills. The questioning approach we used involved flipping the classroom where students were expected learn the lecture material at home by answering a comprehensive list of questions from textbook chapters. They were expected to come to each class period prepared to engage in a discussion of the subject matter, prompted …

Controlling Nanoparticle Dispersion For Nanoscopic Self-Assembly, Nathan S. Starkweather

Master's Theses

Nanotechnology is the manipulation of matter and devices on the nanometer scale. Below the critical dimension length of 100nm, materials begin to display vastly different properties than their macro- or micro- scale counterparts. The exotic properties of nanomaterials may trigger the start of a new technological revolution, similar to the electronics revolution of the late 20^th century. Current applications of nanotechnology primarily make use of nanoparticles in bulk, often being made into composites or mixtures. While these materials have fantastic properties, organization of nano and microstructures of nanoparticles may allow the development of novel devices with many unique properties. …

STAR Program Research Presentations

This summer I interned at the Northwest Fisheries Science Center in Seattle, WA and participated in NOAA’s Salish Sea Project. The Salish Sea Project’s goal is to identify genetically distinctive groups of species in the Salish Sea that may have unique evolutionary and/or adaptive backgrounds. These findings will allow NOAA to promote and monitor the natural production of species in the Salish Sea, to select representative populations for experimental work regarding pollution, ocean acidification and climate change, to contribute to managing the ecosystem for intra- and inter-species diversity, and to help make informed decisions about adaptive management and marine protected …

The Abundance And Distribution Of Gelatinous Zooplankton In The San Francisco Estuary, Amalia Borson, Lindsay Sullivan, Wim Kimmerer

STAR Program Research Presentations

Until recently, gelatinous zooplankton were not considered important components of the San Francisco Estuary (SFE) foodweb. However, anecdotal evidence, ongoing research, and a few published reports and papers suggest an increase in their abundance over the last 10 to 20 years. Of particular interests are three species of introduced hydromedusae (Blackfordia virginica, Maeotias marginata, and Moerisia lyonsi). All three inhabit the fresh to brackish regions of the estuary, including Suisun Bay, the channels of Suisun Marsh, and the western Sacramento-San Joaquin Delta, and are seasonally abundant throughout late summer and fall. As a result, they overlap …

Agent Based Modeling As An Educational Tool, Jonathan H. Fuller, Rodger Johnson, Vic Castillo

STAR Program Research Presentations

Motivation is a key element in high school education. One way to improve motivation and provide content, while helping address critical thinking and problem solving skills, is to have students build and study agent based models in the classroom. This activity visually connects concepts with their applied mathematical representation. “Engaging students in constructing [models] may provide a bridge between frequently disconnected conceptual and mathematical forms of knowledge.” (Levy and Wilensky, 2011)

High School Horticulture Curriculum, Margaret Maratsos

Horticulture and Crop Science

Horticulture is just one of the many topics covered in a high school agriculture curriculum, and yet, there are very few lesson plans or resources available to teachers for these classes specifically. The objectives of this project were to compile a set of lesson plans, lab plans, and tests that would emphasize interactive and investigative learning. The lesson plans were written in such a way that they reflected a certain set of standards, set down by the state of California, and were meant to serve as a bare outline of topics that would be discussed within a week’s worth of …

Teaching Introductory Programming Concepts: A Comparison Of Scratch And Arduino, Anne Beug

Master's Theses

Computing has become an integral part of modern America. The Bureau of Labor Statistics estimates that between 2008 and 2018, the United States will have 1.4 million job openings in computing fields [1]. Since the early 2000's (just after the "dot com bust"), the number of students enrolled in computing majors (Computer Science, Computer Engineering, etc.) dropped precipitously by over 50%, only starting to rise again in 2009 [2]. One way to rectify to this gap between demand and supply is to start training students in computational thinking during high school. While the Computer Science Advanced Placement AB test has …

Using The R Library Rpanel For Gui-Based Simulations In Introductory Statistics Courses, Ryan M. Allison

Statistics

As a student, I noticed that the statistical package R (http://www.r-project.org) would have several benefits of its usage in the classroom. One benefit to the package is its free and open-source nature. This would be a great benefit for instructors and students alike since it would be of no cost to use, unlike other statistical packages. Due to this, students could continue using the program after their statistical courses and into their professional careers. It would be good to expose students while they are in school to a tool that professionals use in industry. R also has powerful …

Matlab Based Algorithm To Find The Remaining State Of Charge, Ishrat Khatoon, Bhaskar Saha, Kai Goebe

STAR Program Research Presentations

Li-ion batteries are one of the most common rechargeable batteries used in portable electronics, electric vehicles, military operations and aerospace applications such as electric air-crafts, spacecrafts, space rovers, robots, etc. Failure of these batteries could lead to reduced performance, operational impairment and even catastrophic failure, especially in aerospace systems. Monitoring the remaining state of charge (RSOC) of these batteries would greatly improve the reliability of the systems powered by them and will ultimately lengthen their lifetimes. NASA's Mars Global Surveyor spacecraft was lost due to battery failure. Hence, it is very important to find the RSOC of the batteries in …

Automation In Cs1 With The Factoring Problem Generator, Joshua B. Parker

Master's Theses

As the field of computer science continues to grow, the number of students enrolled in related programs will grow as well. Though one-on-one tutoring is one of the more effective means of teaching, computer science instructors will have less and less time to devote to individual students. To address this growing concern, many tools that automate parts of an instructor’s job have been proposed. These tools can assist instructors in presenting concepts and grading student work, and they can help students learn to program more effectively. A growing group of intelligent tutoring systems attempts to tie all of this functionality …
