Lemon battery

Material
- 4 x lemos
- 4 x copper nails
- 4 x tin nails
- several cables
- 1 x LED
Supervisor
- 1 person
Group size
- 2 - 4 children
Schedule
-
With the help of the supervising person, the children build up the lemon battery and then test it with the aid of the light-emitting diode (LED).
- Specific questions of electrical conductivity and the mode of operation of the experiment are explained in a child-friendly way.
Conductivity test with a small homemade circuit
Material
- 1x 9 V-battery pack
- 1x breadboard
- 4 wires with stripped ends
- 1x LED with series resistor
- battery clips
- 1x screwdriver
Supervisor
- 1 - 2 persons
Group size
- 5 - 10 children
Schedule
-
Task distribution and subsequent explanation of the worksheet.
-
Structure of the circuit with appropriate assistance, if necessary.
-
Independent testing of the conductivity of various materials, from the pencil case of the children, with the help of the circuit.
- The results of the experiment are then noted on the worksheet and then evaluated with the group.
