This assignment is good for a supplemental activity in a unit on chemical energy and batteries. Use it for a homework assignment, center activity, or for research during an open lab slot. It has a compare/contrast focus, along with an art segment drawing and labeling the 2 batteries. Use it for a grade in Science, Chemistry or Earth Science. Use it for your MG class, as well. It can be graded A, B, C, or D depending on evidence of research, completeness, and effort. Thanks so much for visiting
