E-book, Lesson Plan


Challenge students (usually working in pairs) to create an experiment of their own using pennies and drops of water by following the basic steps in the scientific method. A few ideas … Which will hold more drops of water: cold penny or hot penny; new penny or old penny; and head side or tail side? Student groups have also created experiments to test different substances: different brands of soaps, shampoo/conditioners, or other safe household liquids.Emphasize the need for safety! Each group must have permission before attempting any part of the experiment. If a group has not addressed possible errors or safety rules, have them rewrite the lab until it meets with teacher approval.
