This comparison helps learners comprehend, visualize and remember new concepts. The Apprentice Training Curriculum at the U.S. Naval Recruit Command in Great Lakes, IL, involved a one-hour module on MSDSs in the safety portion of the curriculum. Each group had a different teaching strategy to learn the MSDS terms. While the control group participants were just given the basic definitions of the terms, the other two groups either generated their own analogies or were supplied with analogies. In the final analysis, participants who used analogies or were familiar with analogies and used them as a study tool for the test, were able to recall definitions of hazardous chemical terms and apply definitions more easily.
Absorption is the movement of a chemical into a plant, animal or soil.
This is an exposure route into your body. Absorption can be compared to a sponge used to soak up spilled water. Acute is the short-term effect which occurs when exposed to a chemical for a short time. An example of an acute effect would be a blast of steam on bare skin that causes burns. Adsorption means to collect gas or liquid modules onto the surface of another material.
