Galvanic Elements: Components and Energy Conversion — Assignment, Grade 5

A diagram shows two electrodes immersed in a liquid and joined by a wire. The wire is broken, but the electrodes and liquid remain in place. What change should you expect, and why?

A cell powers a small device. Which observation would best support the claim that the cell, rather than the connecting wire, supplies the energy?

A student draws a galvanic-element model with a chemical reaction in the cell and a complete wire path between the electrodes. Which conclusions are supported by the model? Select all that apply.
