The experiments from this media package thematically belong to subexperiments “A3 Lemon batteries and other batteries” and “A5 Properties of solar cells – Voltage, current, and power” from Experimento | 10+. They have been written especially for the lower grades at secondary schools. They overlap with experiments “A3 Complex electrical circuits” and “A5 Generating energy” from Experimento | 8+.
The three subexperiments “Is a solar cell a voltage source?” “Can wind generate voltage?” and “We create our own voltage source” each include illustrated instructions on preparing and conducting the experiment. Different assignments on the experiment are presented; variation is possible at any time.
