Default Clock making project

Is this for your science project? Wouldn't you rather prefer to perform an experiment of some sort to prove/disprove a hypothesis?

Anyhow, what sort of clock do you want to make? Will a simple sundial do?

Post I got an idea?

Hi,

Manga , I was wondering about your level, is it Middle school or H.S, well I think the idea can go for both.

Using potato Battery to tell time.


* Two copper electrodes. A 10-cm length of thick (0.64 cm) copper ground wire
works well. You'll find it at hardware and home supply stores.

* Two zinc electrodes. Use large galvanized nails, also available from a
hardware or home supply store.

* Three alligator-clip wires (Radio Shack #278-1156).

* Two potatoes.

Now make a potato clock. Open the battery compartment of the clock and remove
the button battery. In the compartment, notice that there are two connections
for the battery marked plus (+) and minus (-). You'll connect the potato
battery to these two places. Let's call the potatoes A and B. Connect A and B
to the clock like this:

1. Insert a copper electrode and a zinc electrode into each potato, fairly far
apart.

2. Use an alligator-clip wire to connect the copper electrode of potato A to
the plus (+) connection in the clock.

3. Use an alligator-clip wire to connect the zinc electrode of potato B to the
negative (-) connection in the clock.

4. Use an alligator-clip wire to connect the zinc electrode of potato A to the
copper electrode of potato B.

I hope that was a help to you.
