Pike Peak Regional Science and Engineering Fair Judging Report

by: Bill Miller  Feb 24, 2024

On Saturday, February 24th the DSES team consisting of Floyd Glick, Dan Layne, Roger Oakey, and Bill Miller participate as special awards judges for the Pike Peak Regional Science and Engineering Fair.

We judged the senior and junior projects by splitting into two 2 man teams.  For relevance and time savings with so many projects to cover, we tried to judge only those projects that had some relevant aspect to what we do in the society involving, space science, radio, computers, engineering, energy, and other related areas.  

We planned to give a 1st and 2nd place award in both senior and junior divisions for a cash award in an amount decided by the DSES BOD and a certificate from the DSES.  However, in the senior group, we found one additional and unconventional research project for this age group and believe that it also deserves a special award, so we have added one additional award in a tie for senior division second place.

Here are the projects and award levels:

Senior 1st Place Special DSES Award:    SD 2 – Waste to Watts: Converting Locally Sourced Organic Waste into Activated Carbon Based Supercapacitors.  Shrey Rohilla,   Grade 11  The Classical Academy High School

Senior 2nd Place Special DSES Award:   SC 5 – Strength of EMF Waves Radiating from High Powered Electrical Lines.  Jessa Book  Grade 10,  Miami Yoder High School

Senior 2nd Place Special DSES Award:   SC 1 – Can Quasars create “dark” Stars using the Dark Matter they Absorb?   Rhianna Williams  Grade 12  Palmer High School 

Junior 1st Place Special DSES Award:   JD 2 – Shopcart 2050.  Advait Jadhav  Grade 7   Chinook Trail Middle School

Junior 2nd Place DSES Special Award:   JD 6 – Object Detection with Raspberry Pi to Help Blind Mobility  Angelina Won  Grade 7  Challenger Middle School

DSES at Jan / Feb Hamfests

DSES was represented at the January NCARC Winterfest and February RMHAM The Swapfest by Paul NO0T and Bill WT0DX.

The Swapfest, held at the Adams County Fairgrounds, was a great event, with good attendance, a lot of equipment for sale and many interesting conversations about DSES with the attendees. We had a great location by the front door, so there was a lot of traffic coming by the booth. Myron KL7YY and Ray AAOL from DSES were also able to attend the hamfest. Paul picked up a pristine Icom 7300 for the DSES HF station at a bargain price!

See the following photos of the booth and general views of The Swapfest.

A New Map of the Milky Way

A new article appearing in the April 2020 Scientific American is “A New Map of the Milky Way” by astronomers Mark J. Reid and Xin-Wu Zheng.

https://www.scientificamerican.com/article/a-new-map-of-the-milky-way/

The article describes recent parallax studies, using Very Long Base Line Interferometry(VLBI) radio astronomy in Japan and North America, to more accurately determine the spiral structure of our Milky Way galaxy. The studies indicate also that the Sun is closer to the central plane of the Milky Way than previously thought.

These VLBI studies utilize natural MASERs that are produced by molecules of water and methyl alcohol in ionized regions just outside hot stars. Hot stars are always short lived, not lasting more than a few million years, because they rapidly burn through their nuclear fuel at their higher temperatures. They therefore are found close to their original location of birth. They are one of the features that define a galaxy’s spiral arms. And so to map the location of the hot star MASERS is a means to map the spiral structure of the galaxy. Radio astronomy VLBI enables angular position measurements to high resolution. The angular position measurements are used to measure the parallax over the course of a year, and therefore measure distance to more accuracy. The more accurate determination of angular position in the sky and distance therefore enables a more accurate mapping.

Three DSES members judge at 2019 Pikes Peak Regional Science Fair

Deep Space Exploration Society members Bill Miller, Gary Agranat, and Tony Bigbee participated as judges at the 2019 Pikes Peak Regional Science Fair. The Fair was held at the University of Colorado at Colorado Springs University Center building on Saturday February 23rd.  This year 115 students from 20 schools presented projects. The purpose of the fair is to encourage students to take more active interest in the study of science and mathematics, to encourage experiment and consideration of science careers, and to provide a means of reward and recognition.  Informally the fair gives students an opportunity to interact with and get helpful feedback from specialists already in the fields.

Bill and Gary were at the science fair to judge and award prizes specifically offered by DSES. The prizes were offered to encourage projects related to astronomy and radio.  However any outstanding STEM project related closely enough to the fields were considered.  Bill and Gary interviewed 17 students in 16 projects at the fair, at the middle school and high school levels, with most of the topics in physical sciences or engineering. A scoring criteria was used based on the qualities of the ideas, hypotheses, methods, data, and lessons learned.

DSES awarded one Senior Division prizes and two Junior Division prizes:

For outstanding senior division project we gave a certificate and $100 to Mark Bloomfield. Mark received 6 additional special awards from other organizations, and he placed 3rd in the Fair’s Senior Physical Sciences category.

• Mark Bloomfield [grade 11] [project SC9], Coronado High School/David Bloomfield: ‘‘Charged up: Testing lithium ion battery performance using a Raspberry Pi load cell’’

For the two Junior Division prizes we gave a certificate and $50 each to Hailey Kressen and Benjamin Homan.

• Hailey Kressin [grade8] [project 8E10], The Classical Academy JHS/Candus Muir: ‘‘A sixth sense: Omnidirectional presence detection system’’. Hailey received 6 additional special awards, and she placed 2nd in the Grade 8 Physical Sciences & Engineering category. 

• Benjamin Homan[8] [8E1], Monument Academy/Karl Brown: ‘‘Does pressure affect carbon dioxide absorption by polyethyleneimine?’’ Benjamin received 5 additional special awards, and he placed 4th in the Grade 8 Physical Sciences & Engineering category.

Tony participated as a general Award Judge for the Fair itself. He judged  middle school social and behavioral science projects.

Tony took a few minutes to take some photos.  The first three photos are from when Bill and Gary interviewed Connor Takenaka about his cybersecurity project. The third includes Tony.

Bill is show interviewing Josh Nakka and Katelynn Salmon for their Senior level science project “Engineering a portable refreshable braille device for improved communication.” Gary is interviewing Jenna Salvat for her Senior level science project “A geothermal analysis of metamorphic lithologies surrounding Cripple Creek and Victor Diatreme”.

Projects Bill and Gary interviewed:

  • “Shields Up” by Samantha Cerniglia. She tested the ability of several materials to block cosmic rays. She built a cloud chamber to do the tests.
  • “LED Lights: Hero or Zero” by Michael Wu. He tested energy efficiency savings claims of a set of consumer LED lights, and found those fell short.
  • “Energy Efficiency” by Samantha Schaefer. She tested the effects of placing different colored filters on solar energy panels.
  • “This Will Blow You Away” by Levi Archambault. He tested the efficiency of windmills with different number of blades, with different wind speed conditions.
  • “Prevent Basement Floods” by Austin Cellar.  He designed and tested a low cost device to detect basement water leaks and flooding, and send an alarm.
  • “Cleaning glasses with portable ultrasonics” by Ty Rockey. He researched, designed, and tested a low cost device to clean eye glasses using water cavitation.
  • “Does Pressure Affect Carbon Dioxide Absorption by Polyethyleneimine (PEI)” by Benjamin Homan. He tested the ability of PEI to absorb carbon dioxide at sea level and 7350 foot elevation pressures.  He utilized previous research by others and theory that predicted lower pressure would result in less absorption, due to fewer number of molecules per volume.  The material would be applicable to CO2 scrubbers in submarines and spacecraft. Benjamin won one of our two Junior Division prizes.
  • “Analyzing how various hydroelectric designs can ameliorate the accessibility of tides” by Chandler Wilburn. He tried to design and test an alternate way to generate electrical power from tides, using a large pressure plate instead of flow past a turbine.
  • “Neodymium field slide” by Amir Laarja. He tested different position configurations of magnets in a generator, to test differences in efficiency.
  • “A sixth sense: Omni-directional presence detection system” by Hailey Kressin.  She designed and tested a system to detect the presence of approaching objects within 1.5 meters in 1 second, to aid people who are blind. Hailey won one of our two Junior Division prizes.
  • “Cybersecurity: Defending our Computers” by Connor Takenaka. He tested the effectiveness of different length and complexity passwords to prevent or delay hacking.
  • “Variable scintillation frequency in muon detection” by Xander Duvall.
  • “Using Solar Radiation” by Erick Lopez.  He tested the effectiveness of several designs for homes to retain heat from solar heating.
  • “Engineering a portable low-cost braille device for improved communication” by Josh Nakka and Katelynn Salmon.
  • “A geothermal analysis of metamorphic lithologies surrounding the Cripple Creek and Victor diatreme” by Jenna Salvat.
  • “Charged up: Testing lithium ion battery performance using a Raspberry Pi load cell” by Mark Bloomfield.  He developed a Raspberry Pi constant load cell to test how temperature, drain rate, and charging patterns affected energy recovered in charging.  Mark won our Senior Division Prize.

Bill presented the DSES awards at the science fair awards ceremony on the following Tuesday, February 26th.
