<p>[QUOTE=&quot;Art, post: 679586, member: 568&quot;]When I had a multi-year teaching assignment with the same group of kids I used anything that I could think of to make classwork fun. I did use coins on a number of lessons and it helped, especially for the students who had some interest. I used cents from 1980 and 1984 to teach the kids how to make a balance to determine relative weights. I also took my students to another science teacher&#039;s class when he soaked Lincoln cents in acid to remove the zinc producing a shell of thin copper with the Lincoln design prefectly preserved.[/QUOTE]</p><p><br /></p>
