2nd Graders had great fun with simply tinkering with a 3v lithium battery and a LED bulb.  We observed both sides of the battery under the microscope.  Our observations helped us understand that we were looking at a battery. The “+” side of the battery was an important observation to help light the LED light.  We tried to light the bulbs and students experimented with lighting 2 and 3 bulbs at the same time.  This colorful lesson was enjoyed by the whole class.
