Annual Report 2014
Mentors: Tony Spadafora & Eric Linder
The LBNL Physics Division hosted its eighth “Physics In and Through Cosmology” workshop for QuarkNet Leadership teachers and high school students. The five day workshop, June 23 to June27, was held at the Lawrence Berkeley Lab. Thirteen high school teachers participated. Eight of the teachers have been active members of QuarkNet for five or more years. Five new teachers joined the group this year. The QuarkNet Teachers represented public and private high schools in the greater San Francisco Bay Area. Also participating were 41 high school students and one UC Berkeley undergraduate student supported through the CalTeach (teacher preparation) program.
The daily format consisted of a hands-on warm-up activity, followed by a presentation. After the presentations, groups worked on hands-on experiments (e.g. QuarkNet acitivty lead by Ken Cecire using data from ATLAS and calculating Hubble’s constant lead by Sean Fottrell). Groups also discussed the lecture and toured the following research facilities: ALS, Molecular Foundry & 88” Cyclotron. Students designed & carried out experiments with Cosmic Ray Detectors. Each group consisted of four to five students and one teacher. After lunch there was another presentation and group work.
The first day focused on getting all participants familiar with concepts & terms in particle physics & cosmology. This was accomplished through “mini” lectures given by returning QuarkNet teachers & CalTeach student as well as through activities.
Formal presentations included:
Bryan Marten (returning QuarkNet teacher) Formation of the elements
Damanjit Hundal (CalTeach Student) Waves / BAO
Miles Chen (returning QuarkNet teacher) Distance Ladders
Natalie Roe (director Physics Division) Welcome to the lab
Sean Fottrell (returning QuarkNet teacher) Gravity: Newtonian to General Relativity
Richard Piccioni (returning QuarkNet teacher) Relativity & Standard Model
Ken Cecire ( QuarkNet) Quark Puzzle activity
Chang Hyon Ha (LBL research Scientist) Icecube- neutrinos for probing the universe
Ken Cecire (QuarkNet) Quarknet activity - ATLAS data
Ian Hinchliffe (LBL research Scientist) ATLAS - Higgs and other LHC Physics
Saul Perlmutter (2011 Nobel Prize winner) Drop by – talk about science research
Glen Melnik & Sean Fottrell (returning QuarkNet) Introduction to detectors
Brian Hayden (LBL research Scientist) Supernova cosmology and dark energy
Blake Sherwin (LBL research Scientist) New CMB results
Freija Descamps (LBL research Scientist) SNO on Neutrinos
Carlos Faham (LBL research Scientist) Dark Matter experiments
Beth Reid (LBL research Scientist) BOSS large scale structure
Eric Linder (LBL research Scientist, QuarkNet Mentor) Q & A session
Students took a pre & post self- evaluation of their knowledge of the concepts in the science standards & some additional concepts from particle physics & cosmology. The scale was from 1 (none) to 5 (thorough). The average gain was 1.42. Concepts with greater than a 2 gain were:
2.2 As something travels faster in space its length appears contracted.
2.3 The intensity of light and gravity follow the inverse square law.
2.3 Cosmology and Particle Physics
2.3 Super Novea occur during certain large star’s life, serving as a standard candle.
2.3 There are four fundamental forces which interact through carrier particles shaping the
Universe.
2.3 Neutrinos are produced by radioactive decay, in stars, accelerators, and reactors.
2.3 Both matter & antimatter exist but the visible Universe is mainly matter.
2.4 Quantum fluctuations in the CMB lead to stars, galaxies and clusters.
2.4 Higgs bosons allow fundamental particles to have mass.
2.5 Scientist use various techniques (Cosmic distance ladder) to determine distances in
space.
2.6 Quantum mechanics uses probabilities to describe subatomic particles.
2.6 The Cosmic Microwave background is the baby picture of the Universe when matter
and energy decoupled.
2.8 Scientist have proposed various theories such as super symmetry & extra dimensions, to
describe the Universe.
2.9 Fermions follow the Pauli Exclusion Principle and make up matter.
3.0 Baryon acoustic oscillations are used as a standard ruler in cosmology
Some comments by the students include:
In truth, this workshop was quite literally out of this world. I had not expected to learn, much less even understand, all the jargon and information from the speakers.
I have a different way of looking at the world and the cosmos.
It was super interesting seeing all the advanced science instruments/machines and hearing the scientists talk about their work was really inspiring.
Majority of the workshop was new to me, so I ended up learning much more than I expected.
Even a Nobel laureate came in and spoke with us about the process of conducting an experiment. Outside the step-by-step pages of handouts teachers gave us, he explained to us the mechanics of creating an experiment essentially from scratch. Overall, I learned not only topics to broaden my understanding of the universe, but also processes as to solving real problems

Purpose –The purpose of this experiment was for students to have hands on experience collecting & interpreting data from muon detectors. All students have had no previous experience using detectors. These detectors were supplied by Howard Matis of LBL.
Methods – After learning how to operate the detector, each of the 10 teams composed of 4 students, 1 teacher & a detector, choose one of the following investigations to determine the rate of flux of muon counts :
- Tilting the detector between 0 and 90 degrees from the horizontal.
- Shielding the detector with books, brass, water.
- Changes in elevation of the detector over a distance of 5 floors.
- Changing the east west orientation of the detector to determine if the collection were muons or antimuons due to right hand rule of electromagnetism.
- Showing the angle of scattering by separating the paddles on a gamma source. This was done by using a particle detector that was made at LBNL through QuarkNet over the last 8 years.
Results - After collecting data groups returned to the large group to report.
Each group gave a presentation of their experimental design & results.
The findings are as follows:
- The data showed the greater the tilt, the lower the flux & at 90 there were almost no counts.
- There was no difference in flux with most of the materials we were able to use.
- Groups did find a difference between the basement of the building & the fifth floor. With the lower locations showing smaller rate of flux. With group discussion it was determined this was due more to the buildings shielding effect than the small altitude difference. However we can’t rule out the elevation difference entirely since one group collected data outside underneath a balcony minimizing the shielding .
- There were 88 more antimuons than muons out of a total count of 1000. A student in the group clearly explained the set up, execution, & physics rules that explained this.
- The group discovered that if the paddles were not in line at 180 degrees, the count falls off. There was much discussion regarding this experiment regarding the nature of the production of gamma rays.
Meaning & future investigations - Cosmic rays have played a large role in the development of Particle Physics. The muon as well as antimatter were first detected by cosmic ray investigations.
This activity gave the students a first-hand experience in understanding & working with particles. Working with detectors also helped the students understand the collection of cosmic rays on much larger scales such as in ICECUBE.
Further investigations could include different shielding materials.
Bryan Marten's presentation files for Stellar Evolution, Origin of Elements, Black Body Radiation
Looks like I'm unable to share my talk on Stellar Evolution, Origin of Elements, and Black Body Radiation with a few slides on CMBR at the end which I didn't have time to get to.
I would like to include the presentation in the following 3 file formats: Apple's Keynote (like PowerPoint), a Quicktime movie which just plays through the slides including the videos (some of which are a couple minutes longer than what I showed this week), and PDF. The problem is that the file size limit for this Quarknet forum is 8MB but each of these formats produces files between 150MB and 1,100 MB in size. If anyone has some suggestions other than using my own personal storage, let me know.

Gravity and Space-time in General Relativity
Attached is the PowerPoint presentation I gave on Gravity at the workshop today. I can't easily upload the code I wrote for the animations, but when I have the chance I'll upload that to some other place and include a link here.
I'm also uploading a pdf of a 1991 article from The Physics Teacher where I gleaned some of these ideas.
