Authentic Science with Micro:bits

BBC Micro:bit

The BBC micro:bit is an inexpensive, pocket-sized computer that is easily programmed to communicate messages and collect data. Within this page are sample ideas on how to integrate a Micro:bit in your classroom for data collection and analysis.

Here is a video for further interest: BBC Micro:bit

Sensors on the Micro:bit

• Accelerometer

• Magnetometer

• Temperature Sensor

• LEDs can measure light intensity

• Can measure voltage

Micro:bit - Temperature Data Collection

MakeCode provides students a platform to code and to simulate the built-in sensors of the micro:bit.

Here is a sample Simulator Temperature Data Collection Code for students to collect real-time data for further analysis where the physical Micro:bit is not required.

Students with access to a Micro:bit can download the same code from above to the device and collect real-time temperature data within the room. Once the data has been collected, it can be exported to an excel program for further analysis.

Micro:bit - Remote and Receiver

Extending on the previous activity, students can code 2 Micro:bits to share information between the pair via radio transmission to collect real-time data from locations a researcher may not want to take a computer.

Light Intensity

The Micro:bit has a light detector sensor built into the device. Students have numerous options to code for light intensity and detection with various extensions limited by imagination and curiosity.

Here are some examples of code students could remix:

Changes in Height and Direction

Micro:bits has 3 accelerometers

X - tilting from left to right.

Y - tilting forwards and backwards.

Z - moving up and down.

Students can use data from the z accelerometer to capture changes in height.

Challenge Students to throw the best parabola within class.
