- Can the energy in a button cell battery be seen?
Summary of Lab
In small groups, students will place a piece of bologna on a noncombustible surface. They will place one dropper full of saline in the center of the meat slice, then place a button cell lithium-ion battery in the pool of saline on the bologna. Using a timer, they will observe what happens each minute for 10 minutes.
