Science on Stage Europe The European platform for science teachers

Fast and Curious: Speed, acoustics and the Doppler effect (iStage 2)


One way to excite students for problems in physics is to call their attention to the physics in situations of daily life. In the teaching unit ‘Fast and Curious’ students investigate why we can distinguish if a vehicle is closing in or gaining distance by using our sense of hearing alone.

For this teaching unit the students should be at an age between 17 and 18 years, for certain knowledge in physics and mathematics is presumed.

The project is taken from the brochure ‘iStage 2: Smartphones in Science Teaching’ from the topic ‘ears’. The complete brochure can be ordered free of charge (Mail at or downloaded. It was developed by 20 teachers from 14 countries around Europe. The project was proudly supported by SAP.
