Bricker to Speak on Teaching Innovations
Clark Bricker, professor of chemistry, will present ideas for innovations in the teaching of chemistry at a symposium tomorrow afternoon in the Kansas Union as part of the 9th Midwest American Chemical Society Regional Meeting.
'innovations, just for the sake of innovations, have, in my opinion, very little value,' said Bricker, who has received the HOPE award twice.
Bricker said he hoped his innovations would interest nonchemistry students as well.
He said he tried to teach the practical aspect of learning basic chemical principles
by having his students think of personal experience as the basis for them to learn theories and principles.
"I try to teach from reasoning in a logical fashion," Bricker said.
BRICKER SAID HE WOULD discuss such things as the "greenhouse effect," the energy ciris and a practical application of theories and theories to them at the symposium.
The energy crisis, Bricker said, might possibly be tackled with a purely chemical approach. He argued that on by means of sunlight and would be used to generate electricity, he said.
A purely chemical solar cell would be less expensive, Bricker said, since an existing solar cell costs about $50 a watt. A purely chemical solar cell would have to be regenerative, however, so that nothing would be used up, he said.
Bricker said that the "greenhouse effect" would be used to explain an equilibrium system and a system not in equilibrium. Bricker explained why the earth has become warmer.
equal to the amount of energy absorbed from the sun.
The recent increase in pollution has caused more carbon dioxide and water to be released into the atmosphere. This pollution has resulted in less energy being radiated from the earth and more being emitted by it, leading to global warming.
THE EARTH HAS constantly radiated energy from the sun into interstellar space. For thousands of years, Bricker said, the amount of energy radiated by the earth was
Bricker said this example could be used to illustrate fundamental chemical principles to students in introductory chemistry courses.

positions. Two other symposiums are scheduled for tomorrow morning and afternoon, one on the study of enzyme actions and another on the dating of ceramic objects, Bricker said.
About 500 chemists from the midwest are expected to attend.
Lawrence Surplus Has Just Enough Levi's To Go Around.
Sharing a pair of Levi's can be fun, though it does cause problems stepping, stopping, stamping or stooping.
So, if you're the type who likes a pair of Levi's all for yourself, your place is at Lawrence Surplus.
You see, Lawrence Surplus has just enough LEVI'S to go around-just enough so you can get the type of jean you want. in the color you like, in the size you need.
So, whether you need one jean for two or two for one, come to Lawrence Surplus-the store with just enough LEVI'S for you.
