Can we help Captain Kirk power

up his Communicator using lemons?

A lemon Penny Zinc coated screws Multimeter 2 alligator clips

1. Insert penny & zinc coated screw into the

lemon.

2. Connect 2 wires with alligator clips to the

penny and the screw.

3. Connect the Multimeter to the other end of

the two wires.

4. Measure the voltage

All batteries have a "+" and "-" side. The Lemon Battery in the picture shows

Copper = positive (+)Zinc/Steel (eg. paper clip) = negative (–)

Yes, now we can help Captain Kirk get back

to his spaceship ! Yippie!

1.5 V + 1.5 V + 1.5 V + 1.5 V =

1. Connect the penny of one lemon to the zinc screw of the next lemon.

2. Measure voltage.

3. Repeat to connect 3 lemons.

4. Measure voltage again.

( You should have one lemon with penny unconnected at one end and one lemon with zinc screw unconnected at the other end. )

Use alligator clip to connect the lemon battery to the Digital Clock.
