“Chemistry on Mars”
Social and Check-in: 6:00PM
Dinner: 6:30 PM
Featured Speaker: 7:15 PM
Overview of Program:
Mars has intrigued mankind for at least 2000 years BCE. Telescopic work over centuries starting with Galileo 1610 identified polar caps that changed in size, permanent features, yellow clouds and some interpretations of (blurry) features that later proved incorrect such as canals and a wave of darkening. These interpretations were carried further to suggest a system of irrigation and annual flourishing of flora. While none of these proved to be true, the search for life on Mars is still pursued vigorously.
Pictures from spacecraft starting with Mariner 4 (1964) altered the nature of studies of the surface of Mars. The increasing level of detail in the imagery show no canals but have features that suggest large quantities of flowing water were once on the surface of Mars. Pictures detecting details as small as about 30 centimeters show clear evidence of annual melts and minor water flow in the polar regions – consistent with the existence of the permanent water ice cap and permafrost region.
The evidence for the prior existence of a massive amount of water, however, is still a matter of some debate. Investigations increasingly use measurements by Mars rovers of the chemistry of surface materials to look for unambiguous evidence for an early aqueous environment – an environment that is also considered to be the most propitious place to search for evidence of extinct, pre-biotic and extant life on Mars .
Dr. William Smythe is a native Californian who greatly enjoys discovering how the solar system works. At UCLA he received a doctorate in Geochemistry and devoted 25 years to conducting a research program in Antarctica on oscillations of the Earth's inner core and the Earth's free oscillations.
He is presently a principal scientist at JPL, specializing in understanding the composition of the surfaces of planetary bodies, and producing cutting edge science instruments like ones that flew on the Deep Impact. He is currently engaged in designing new missions to the planets, in building a miniature spectrometer to fit within a drill for a future Mars mission, conducting laboratory research on the transport of light in snow and the origins of the methane and nitrogen currently in Titan’s atmosphere. He has participated in many flight missions including Viking, Voyager, Galileo, Mars Observer, and Deep Impact.
Dr. Smythe has been a strong supporter of education and outreach for many years, often speaking to the public, at student career workshops and at teachers' workshops on deep space missions.
Dinner will be in the Blue Sky Café at AQMD and consist of a selection of gourmet wraps. The freshest gourmet ingredients wrapped in flavorful, colorful tortillas served hot or cold with one side dish and cookies. Choices include chicken caesar, turkey bacon club, cold cut meats, southwestern chicken, and grilled vegetables. A side salad and cookie are included.
Cost and Reservations: The cost (meal, tax and tip) is $12 members, $15 non-members, $10 seniors and retirees, $7 students with ID. Cash or check only please, at the door. Please make your dinner reservations no later than 12:00pm midnight on Sunday, March 17 by contacting Eileen DiMauro (email@example.com, phone (909) 274-4533).

You Have Your Chemistry Degree! Now What?

Lake Elsinore Girl Scout Troop 1124 loves science! Their leader contacted the San Gorgonio Section to invite a chemist to visit the troop. Mt. San Antonio professor Eileen DiMauro attended the next meeting. She conducted a demonstration of the scientific method. The girls were tasked to develop an experiment that would would allow them to conclud which of the two polymers, Silly Putty or Slime, is more fun to play with.

The San Gorgonio Section hosted several NCW events throughout the section. Please scroll down to view them!
PALM DESERT, CA—The Marywood-Palm Valley (MWPV) School’s 10th grade chemistry students joined College of the Desert chemistry students on Oct. 26, to celebrate a holiday nationally recognized by chemistry teachers: Mole Day. Twenty-one Marywood-Palm Valley students traveled to the COD campus and participated in a college-level chemistry lab.
Students spent four hours on the COD campus and worked with Associate Chemistry Professor Joana Ciurash’s chemistry lab on projects including single and double displacements reactions, melting point experiments, titration experiments, and gas chromatography experiments. MWPV chemistry teacher William Kim said his chemistry students were excited about being in a college-level chemistry lab. “The students will be making ice cream using liquid nitrogen. They can’t wait,” Kim said.
COD contacted Kim to invite his class to the campus to celebrate Mole Day. “This would not have been possible if not for the overwhelming support from the past and current college presidents and deans,” Ciurash said.
“My goal in taking students to celebrate Mole Day is to help them see the bigger picture for chemistry and its applications,” explained Kim. “I am excited to help make chemistry relevant to our students and want the students to see some of the more advanced chemistry techniques coming out of a college-level classroom.”
This spring, Kim’s senior-level physics class launched a weather balloon into the stratosphere, using a weather balloon kit and curriculum from the University of Texas.
Mole Day has been celebrated annually on Oct. 23 from 6:02 a.m. to 6:02 p.m., Mole Day commemorates Avogadro’s Number (6.02 x 1023), which is a basic measuring unit in chemistry. Amadeo Avogadro (1776-1858) discovered the measurement unit. Mole Day is celebrated in chemistry classes throughout the nation each year in an effort to foster interest in chemistry among students and the public.
Mole Day is an unofficial holiday first written about in an issue of The Science Teacher in the early 1980s. Maurice Oehler, now a retired Wisconsin chemistry teacher, was inspired by the article and founded the National Mole Day Foundation (NMDF) in May 1991. Some schools celebrate Mole Week around the Oct. 23, Mole Day date.
