Students will:
• learn about the materials for doing electronic experiments, e.g. breadboards, experimentation sets.
• learn how to use the materials to set up electronic experiments.
• experience and learn the basic components of an electrical circuit.
• learn about circuit diagrams and symbols for electronic components.
One item deals with „Technical application and vocational orientation“.
Information and ideas:
• Be sure to inform the students about the dangers of electricity and safety measures to avoid them. Point out that the voltage used in the experiment is harmless. However, emphasize that household voltage is much stronger and can be dangerous if handled incorrectly.
• Since the students are working with the materials for the first time, explain the individual components and specify their purposes.
• The experiment works equally well with an incandescent bulb instead of the buzzer.
For our worksheet, we have chosen a buzzer simply because incandescent bulbs are prone to break and must then be replaced. If your students use incandescent bulbs in the experiment,
make sure to point out in the ”Analysis and reflection” that the bulbs do not produce light but heat: The wire filament is heated to such a high temperature that it glows with visible light.
• Point out the dangers of a battery being short-circuited.
• Point out that the circuit diagram uses abstract symbols, which represent real components.
• learn about the materials for doing electronic experiments, e.g. breadboards, experimentation sets.
• learn how to use the materials to set up electronic experiments.
• experience and learn the basic components of an electrical circuit.
• learn about circuit diagrams and symbols for electronic components.
