Stem Discovery Week at Kareas High School

The BBC micro:bit was used for all our activities. The BBC micro:bit is a pocket-sized computer that can be coded, customised and controlled to bring your digital ideas, games and apps to life.

With 112 students from the A and B classes in our school, we did the following activities.

Using the micro:bit we built a temperature alarm for egg incubators. We used the temperature sensor of the micro:bit to sound an alarm and flash a light if the temperature was not appropriate. Concepts studied from physics included temperature measurement, open and closed electronic circuits, electric power, electric current, and earthing and from programming we studied the selection structure, logical operators “and / or” and event-oriented programming, and input and output.

More specifically using the Microsoft MakeCode block editor for the BBC micro:bit, we wrote a programme that monitors the temperature. If it was less than 37o C or more than 38o C, it played the note C (4 beats long) on a loop as an alarm, and scrolled the temperature on the display.

Otherwise, if the temperature was safe, it stopped playing the alarm and displayed a happy face. We set the temperature in the simulator (by dragging the arrow), to test our programme. Then we connected a buzzer using crocodile clips, explained the open and closed electric circuit and earthing and we tried a colourful LED as another output.


We pointed out that this is the principle used by a thermostat to control the central heating at home, or the climate control in many modern cars.

Then we discussed that as well as external outputs, such as a buzzer, or bright/coloured LEDs, one could also attach external inputs as sensors. We could use an external moisture sensor to detect the dampness of the soil in a plant pot. It could be used to sound an alarm to remind you to water the plants or even better the micro:bit could turn on a pump to water the plants automatically.

Then we discussed an activity we perfomed earlier this year using the light sensor of the micro:bit to switch the lights of the display on and off according to the light that falls on it. The light sensor of the micro:bit detects the light intensity falling on the 25 led display. We had made a programme which turned on a number of LEDs according to the light falling on the display, i.e. 0 LEDs when it was really bright, 1 LED when when it was bright, 9 LEDs when it started getting darker, and 25 LEDs when it was really dark. We discussed the model we had made and pointed out that this is how most modern cars have automatic systems to switch their lights on and off as the light level changes. Similarly, it could be used for an automated lamp in a room or a micro:bit could be attached to the back of a bike’s saddle to create a smart rear lamp.

We also said that these could be models for the Internet Of Things Devices and we discussed this.

The following activities were done with the 25 students of the C class.

The micro:bit was used to light up LEDs, change their brightness and play music.
We built an electric circuit with the micro: bit, using fruits, human bodies and other conductors of electricity to light up LEDs, play notes on a buzzer or our headphones and change the brightness of the LEDs. From physics, we studied the concepts of Open and Closed Electric Circuits, electric power source, electric current, earthing, electric conductors and insulators, and parallel and serial resistor connection, and from computer science the concepts of Input, Output, repetition, and Event-Oriented Programming.

We discussed how we could extend the fruit keyboard we made to make a beat box.

We also studied ‘Ohm’s Law’, which connects Voltage V, Current I, and Resistance R with the formula V=I*R. We connected a LED through a resistor at pins 3V and GND. As we increased the resistance, the LED became less bright and vice versa. In a similar way we studied the serial and parallel connection of resistors.

Training Courses KA1 for Professional Development

Participants: Mr Alejandro Luana Cabal; Mr Antonio Albiol; Mr Bojan Radistic; Mr Kristian Dokic; Mrs Ana De Blas Gonzalez; Mrs Eirini Arnaouti; Mrs Esther Rodriguez and Mrs Panagiota Argyri in a training session for professional development via Erasmus+ Key Action 1 (KA1 is a mix of decentralised projects run by National Agencies and centralised activities managed by the European Commission’s Executive Agency).
The topic of the training session is “Game-Based Learning Course about Theory and Practice of Serious Games & Gamification”.

Mathematics Domino “Fractions” Tournament

On 23rd April, during the STEM Discovery Week 2018, the Mathematics Domino Tournament “Fractions” took place at 1O Teodor Traianov School, Sofia, Bulgaria. Students from 5th and 6th grade participated. The aim of the tournament was at developing mathematical thinking through games. Special mathematical domino tales made by Tonediko were used for the activity.

Stars’ Light

Here is our STEM Discovery Week 2018 activity! „Stars’ Light” is a Go-Lab Inquiry Learning Space I implemented with a class of 16 students on 20 of April 2018, in order to demonstrate to them the connection between numbers and fractions they learn about in mathematics class, poems they learn about in literature class and velocity, stars and light concepts they learn about in physics classes. This space helps also to understand the space-time relationship to an astronomic level.
