This student guide supports students as they interact with a slice of bologna, a button cell battery, and a dropper of saline solution and observe the results over time.


Through the bologna test, we can visualize some forms of energy transfer. You can replicate the bologna test or observe it through the video.

The bologna test is performed with a lithium primary cell, which is not rechargeable. Lithium primary cells are different from lithium-ion cells, which are rechargeable. However, you could expect a similar reaction from a lithium-ion battery.
