Have a need to work with less hazardous materials? This publication describes 15 common experiments in which less hazardous chemicals are substituted for the ones traditionally used. Comb bound, Rena Benedict, Forest Lake High School. Edited by Richard Clark, Minnesota Department of Education. Distributed by LSI – 1987.
It is the intent of this publication to promote science teaching in which students preform experiments rather than read about them. When students’ experiments involve hazardous or toxic chemicals, teachers need specific information to develop guidelines which fulfill their legal responsibilities and ensure safety for both student (short-term exposure) and instructor (long-term exposure).
