Hypothesis: When placed in a ____________

at a distance of __________ the __________

and __________ metals will make the best battery.

Safety: Wear goggles and wash hands after lab.


Lemon and potato wet cell batteries

Procedure: (8 steps)

Preparation of Lemon and Potato

Soften the potato and lemon to increase juice production

Use 1cm, and 2 cm distances between electrodes


Data table volt readings

Data Table: Volt Readings


Bar graphs 2 stackedbar

Bar Graphs (2) StackedBar

1 graph for the lemon and 1 graph for the potato

X axis C-Z, Z-S, S-C

Y axis Voltage

6 bars for each graph 1 bar for1 cm and 1 for 2cm


Questions

Questions

  • What combination of metals and distance produced the highest voltage?

  • If you change only the distance but use the same metal strips, what is the effect on voltage?

    3. Which makes a better battery? Explain why.
