Show New Technique Aida in Teaching of Chemistry AMES, IOWA. Chemistry now is fun at Iowa State college ever since it tangled with streamlining and came out second best For Iowa State has adopted "semimi-cro" "semimi-cro" chemistry. Test tubes no bigger than the little finger liquids measured in a medicine medi-cine dropper that is "semimicro" or "midget" chemistry. And this science on a small scale has injected inject-ed a new fascination into the college curriculum. tn semimicro chemistry students need use only one-tenth the chemical chem-ical material as under the old, or macro-chemistry system, but that isn't the only advantage. Perhaps the most important thing about this streamlined version of chemistry is that it makes the laboratory lab-oratory a healthier and a safer place. Since chemicals used are cut to fractions, so are laboratory odors. Existing ventilating equipment can whisk away in a jiffy the fumes formed by chemical processes during dur-ing the experiments. |
