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.
Information and ideas:
• Observe the safety information in these instructions as well as in the teacher information related to the experiment and discuss them with your students.
• Also observe the applicable safety guidelines for your school.
