FIRST VERSION
In the following, first we list the simple steps need to play the activity in its basic form. You may arrange the equipment and decide which measurements your students will have to perform, i.e. build your own "Learning scenario” suitable to your students age and background.
Later we suggest a more complete scenario, suitable for 14 to 14-years old students and shows the results.
- Hang a spring over a proper support and attach a mass to it. Start an oscillatory motion.
- Place the mBot ultrasonic sensor below the spring in upward vertical position, so that the ultrasonic sensor see the mass (eventually enlarge the mass surface by a cardboard).
- Press the on board button to start measurements. The oscillation period is shown on the led display and the spring constant can be evaluated.
- Discuss the importance of such a relatively simple phenomenon through the dedicated supporting material (see attached presentation).
