Time gates: measuring speed with micro:bit
Show details
Estimated duration: 5 x 45 minutes
Age level: Primary school students
Learning objectives, skills and competencies
Students will develop hard skills such as coding and conductivity, while familiarising themselves with physics and electronics. They will also develop a critical approach while solving problems, and work constructively in teams.
Activities and roles
In this project, students will develop a speed gate system, where a small toy car will be set loose on a ramp, achieve speed through gravitational force and go through two contacts that are connected to a micro:bit. This will measure the time spent and calculate the speed of the car. Students are expected to design and build the ramp, develop the contact-based time gates and code the routines that allow speed to be measured. The teacher monitors the activity and assists whenever possible.
