[1] Join us for Exploring Your Universe, our annual Science Day at UCLA. Demonstrations, hands-on activities, and more. Free admission! Go to event website [1].
Outreach Using Physics Demos
The Instructional Resource Lab, which provides lecture demonstrations for teaching physics and astronomy, also supports faculty and staff outreach efforts with demonstration equipment, advice and training. This is done as a purely volunteer activity. Below is a partial list of activities.
Kid's eye view of bed of nails, hair-raising electrostatic charge, pendulum motion of a bowling ball, and singing with helium (high) and sulfur hexaflouride (low).

Cesar Chavez Day 2010
Over 350 people attended the event. From the 280 who signed in, we found 7 physics professors, 19 physics students, 66 who identified as UCLA students, 7 from the Art Deptartment, 32 8th grade physical science students from Paul Revere, 22 honor students and 8 parents and teachers from Cals Early College High School, 5 other high schoolers, 10 other middle schoolers, 5 elementary schoolers, 6 from the Boy Scouts and 6 from the Cub scouts. The rest were from other universities or undetermined.
John and Craig smooth the bed of coals.
David measures the temperature with an infrared thermometer that goes up to 900 degrees F. It went up off the scale, above 900 degrees. It was hot.
After walking across the coals, Walter explains the physics behind it.
Pierre walks across the coals.
Marvin walks across the coals into the pan of water at the end.
The audience is astounded at the foolishness they see.
One of Harry's two handmade fire barrels.
11 people walked across the coals and survived with minor burns. Some audience members wanted to walk and were disappointed to learn that only faculty and staff could walk.
How can you walk across hot coals? [12]
Fights almost broke out over Pluto.
Shadows on the phosphorescent wall. People also enjoyed writing on the wall with LED's. They quickly found that the red and green LED's didn't work for writing. They needed to excite the phosphor with a blue LED, higher in frequency than the green phosphor emission.
Total internal reflection in various plastic light pipes.
Laser light inside a water stream, showing total internal reflection.
Water stream with light bouncing inside hits a hand.
The light portal was really a 3-Dimensional illusion. You can only get some idea of what it was like to walk through it from this 2-D picture.
Black light tent.
A stereo viewer sculpture by Franklin Londin held 3-D images of Tesla coils and skulls.
Art wears electroluminescent (el) wire. El spider.
Sodium Light.
More images and video to come. If you have good images or video, please send them or contact me at msimon at physics.ucla.edu
Day of the Dead 3-D Teslathon
Friday November 2, 2007 6:30 -- 9 pm
UCLA Knudsen Hall Outdoor Patio 2-222
Light sabers, costumes, day glo, light art encouraged
Complete Schedule of Events
Parking
The best parking lot is Lot 2 at Hilgard and Westholme. Parking in the lot costs $8. There are new metered spaces in Lot 2. There is metered parking along Charles Young Dr. near the parking kiosk at $0.25 per 15 minutes with a 2 hour max. Bring quarters.
Maps
Here is a clickable map [14]. Click on Knudsen Hall or inverted fountain. There will probably be signs pointing the way.
Exploring Your Universe Fire and Ice Demo Show Nov. 13, 2010
Art Huffman breathes out liquid nitrogen:
Liquid oxygen looks pale blue:
What happens if we add liquid oxygen to glowing steel wool?
Let's try that again:
Burning magnesium inside a block of dry ice. Oxygen is pulled out of the CO2 leaving black carbon:
Video projection of paramagnetic liquid oxygen sticking between the poles of a magnet:
Highly pinning superconductor is suspended upside down on a magnet track:

The Laser Symposium slides are posted here [17]. Videos of the presentations will be posted shortly. | Six of the Presidential briefings from our faculty [18] to Barack Obama are now posted. Issues addressed include nuclear power, weapons, plasma technology, fusion energy, manned vs unmanned space exploration, federalization of education, science's role in society, and the role of industrial research labs. | Brandon was the winner of the Science Challenge [19]. This 3-D book was his prize. |
Nuclear Power and Nuclear Weapons | Plasma Physics and Fusion | Space--Manned vs Unmanned |

In cellular respiration sugars are oxidized and the resulting energy is stored in molecules of ATP. Each gram of sugar produces about 3.75 kilocalories or 16 kilojoules of food energy. The average human body utilizes about the same energy as a 100 watt light bulb. 100 watts x 24 hours x 3600 seconds/hour = 8,640 kilojoules per day.
If we got all our energy from sugar and starch, we would need about 540 grams/day which is just over 1 pound per day. (Starvation is considered to be less than 1800 kilocalories or 6,830 kilojoules per day.) What does the energy locked in 1 gram of sugar, 16 kilojoules, look like? Let's oxidize a gram and see.
If we could power our bodies with electricity from the utility it would take 2.4 kilowatt hours to operate at 100 watts for a day. At the rate of about 10 cents per kilowatt hour, the energy would cost 24 cents.
The class started by breaking into groups, racing up Janss steps, measuring time, height, and weight to calculate how much power a human could deliver.
Then figuring out the worksheets to get answers
Later we did a minilab to measure the speed of light.
Other activities were planetarium shows, a talk from Professor Cowley about the energy crisis and fusion energy, and a physics demonstration show.
