From the Chair

November is an event-packed month for our Section. National Chemistry Week, November 5-11, is an opportunity for all chemists in the greater Cincinnati area to become part of a national movement to recognize the positive influence that chemistry has on our society. Each year more ACS members across the country are participating in activities that enlighten the public about the benefits of our profession. Our NCW Chair, Larry Sallans (482-2371), would be happy to direct you to one of the many activities his committee has planned for the week. We can use your help; take that first step -- call Larry and become part of a very rewarding experience.

On November 15 our section meeting will be at the Faculty Club of the University of Cincinnati for the Oesper Award Presentation. This year's honoree is Dr. Greg Choppin, R. O. Lawton Distinguished Professor of Chemistry, in the Department of Chemistry at Florida State University. The Oesper Symposium is an annual event sponsored by the Department of Chemistry at the University of Cincinnati and the Section is honored to be a part of this festive occasion.

Region II, which encompasses our Section, is holding elections for Director; the candidates statements appeared in the September 25 issue of C&E News and the ballots are to be returned to National by November 20, 1995. The October Cintacs had abbreviated statements for each candidate in the Advertisement section; DON'T FORGET TO VOTE!!

Finally, be sure to return your Section survey (October Cintacs) in time for the prize drawing at the November 15 monthly meeting.

Dr. Ralph E. Oesper

Ralph Edward Oesper was born on June 14, 1886, in Cincinnati, Ohio. Entering the University of Cincinnati in 1904 he took his B.A. (1908), his M.A. (1909) and his Ph.D. (1914) degrees from the Chemistry Department under Lauder William Jones. After brief periods at New York University and Smith College, Oesper returned to the University of Cincinnati as a member of the chemistry faculty in 1918, where he remained until his retirement in 1951. However, this did not end his service to the University, as he continued to remain active as Professor Emeritus almost to the day of his death, 26 years later, at the age of 91.

Oesper was a prolific writer, publishing more than 300 papers in the fields of analytical, organic, and colloid chemistry and especially in the history of chemistry. He also used his mastery of the German language to translate nearly two dozen books in these fields, as well as countless articles. He served on the editorial boards of the Journal of Chemical Education, Chymica, Mikrochemie, Mikrochimica Acta. In recognition of his activities, he received the Eminent Chemist Award of the Cincinnati Section of the ACS, the Dexter Award in the History of Chemistry, and an honorary doctorate from the University of Cincinnati.

Oesper's many interests and activities, as well as his dedication to the University of Cincinnati, are reflected in his bequest to the Department of Chemistry, which was made in both his name and that of his wife, Helen Wilson Oesper. The bequest has been used not only to establish the annual Oesper Symposium, but to establish a faculty position in Chemical Education and the History of Chemistry, to support a yearly departmental colloquium on the History of Chemistry, to establish a scholarships for outstanding high school chemistry students, and to purchase new additions of the Oesper Collection of Books and Prints in History of Chemistry, which currently houses nearly 3,200 books and journals and about 1,800 photographs and prints relating to the history of chemistry.

News for the Classroom

It is already the seventh week of school and everything is off to a busy start. Around the area, schools are adjusting to implementing the new State Science Model. The proficiency test will now include a science section.

Discrepant Events

One of the methods I have been using in my classroom is discrepant events. Each Friday we have a DEF (discrepant event Friday). Two demonstrations are set up. One is from the week before and one is new. When a DEF is first presented students must write about their observations (thus practicing writing across the curriculum). This teaches them about making observations - not inferences, conclusions, etc. It is a quiet time as everyone tries to observe everything because they don't know what is or isn't important at this point. Then, they start their explanations of the phenomenon. They have a week to continue their explanation and work on an extension. For their extension, they have three choices. They may go home and show their families (thus involving them in the process) and write their families' explanations; they may find a practical application for the phenomenon (thus bringing in applications); or they may devise another demonstration showing the same phenomenon (synthesis).

For the first one of the year, I fill an aquarium with water and place an assortment of soft drinks in the aquarium. Some float and some sink. Most people immediately get part of the answer but do not realize there is one answer for why some sink and another answer for why some float. Other examples have included "dancing raisins," "changeable markers," effect of cleaners on golden rod paper, steel wool in vinegar, and more. I tell them that there is no magic involved - what they observe is really what I am doing. Second semester, students take turns performing a DEF or DEW (discrepant events on Wednesdays) and have hung keys on a strand of hair, demonstrated the magic defroster, ignited steel wool with a battery and many more.

Several of these were displayed for Parents' Open House and the parents had a chance to search for a solution.

Teachers' Workshop Scheduled for March 9, 1996

A workshop for all those interested will be held Saturday, March 9, 1996 at the College of Applied Science. We are working on the speakers but hope to have a Nobel Surprise. There will be a continuation of the Internet workshops, CBL probe labs, and some examples of lessons to use in implementing the new Science Model. We are working on incorporating some sessions for teachers of physics, biology and geology.

Education Discussion Group

The Education Discussion Group is a time for everyone (teachers from grades K-16 as well as people from industry) to gather together to share ideas that work in the classroom, to ask for help, to order special supplies, to share what is happening in the world of chemical education, ant to share in the excitement and fun of the classroom.

Our first meeting was held in September at Sycamore High School. Several teachers shared demonstrations they had seen this summer, calendars were marked, new catalogs were distributed, and the mailing list was updated. We then worked for about an hour on CBL labs with the Texas Instruments TI-82 calculators interfaced to a computer. The next meeting is Tuesday, October 24, at 7:00 PM at Oak Hills High School, 3200 Ebenezer Road, 922-2300.

We meet monthly at various locations. We urge you to join us. Please look at the planned dates and times.


1. If you have any changes of address, please send them to Ed Escudero immediately.

2. Cincinnati State Technical and Community College is looking for someone to teach organic chemistry at night. If interested, please contact Jim Bronstrup at 569-1704.

3. Summer Internship for Minority Secondary Science Teachers - There will be a program in the summer of 1996. If interested, contact Ted Logan at 627-2751.
