Die Materialien sind auch in deutscher Sprache im Lernobjekt "Experimente zu Strom" verfügbar (siehe "Auswahl verwandter Medien"). 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+ ("Externe Links"). They have been written especially for the lower grades at secondary schools. 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.

Inhalt - Electricity: Electricity experiments (teacher information) Teaching method for teachers for the “Electricity experiments” media package.
- Electricity 1: Is a solar cell a voltage source? (student instructions) The students will observe a circuit with a solar cell under various light sources. They will measure the voltage and record their results in tables. The instructions first include a photo and a list of the required apparatus and materials. Text and pictures explain the preparations for the experiment step by step. Then several assignments are presented: The students should express their guesses, conduct the experiment, and note down their observations.
- Electricity 2: Can wind generate voltage? (student instructions) The students will blow on a propeller (motor) in the circuit with one and two LEDs (in series and parallel connection), varying how hard they blow. They will measure the voltage and record their results in tables. The instructions first include a photo and a list of the required apparatus and materials. Text and pictures explain the preparations for the experiment step by step. Then several assignments are presented: The students should express their guesses, conduct the experiment, and note down their observations.
- Electricity 3: We create our own voltage source (student instructions) The students will create their own voltage source using water, citric acid, a copper nail, and a zinc nail and connect a motor with a propeller. They will measure the voltage and record their results in tables. The instructions first include a photo and a list of the required apparatus and materials. Text and pictures explain the preparations for the experiment step by step. Then several assignments are presented: The students should express their guesses, conduct the experiment, and note down their observations.
Serienbeschreibung Die Serie stellt Materialien aus dem Medienportal der Siemens Stiftung zur Verfügung und gibt somit auch einen Überblick über die dort vorhandenen Medienpakete. Zur Nutzung der über den externen Link erreichbaren OER-Materialien bedarf es keiner Registrierung. Für andere Bereiche des Medienportals der Siemens Stiftung ist eine solche ggf. notwendig.
