Sci-Tech fair: Innovative ideas by SHS students that will inspire you

The education system today focuses on books and rote-learning, but times are changing as these young geniuses, who chose to take a different path, have proved.

They have picked machines over books and ideas over words.

The ignite competition held by National Science & Maths Quiz (NSMQ) through the Science and Technology Fair as part of its edition is a platform that is giving young minds a place to experiment and innovate, and come up with something extra ordinary.

The 3rd edition of the two-day Fair took place in March 2019 at Sunyani in the Brong Ahafo region.

The fair provided participating schools with the opportunity to use science projects to demonstrate some of the concepts they have studied in school.


The aim of the event was to give students the opportunity to put into practice the theories learn in the classroom.

Here are some interesting and impressive innovations by students of various schools at the 2019 Science and Technology Fair.

1. SHS students of Sekyedumase SHTS in the Ashanti region designed a programmable lawn slasher.

It is made with PVC pipe, battery, bluetooth device. It can be programmed to slash lawns without someone directly handling it.


2. Students of the St. Monica's SHS designed Solar Generator. It is designed to tap the sun free energy. It consists of solar panels, two volts batteries connected in parallel, inverter board and a load.

3. Students from Sekyedumase SHTS developed an electronic quiz bell. The bell determines who rang it first and disconnects all other contestants during a quiz competition.

4. Students from the Sekyedumase SHTS at the Science and Technology Fair also developed a touch-less dustbin.


The dustbin is made with an ultrasonic motion sensor, servo motor and Arduino. The lid opens when one gets close, allowing the person to drop the liter and closes again. 

5. This is an IoT Home Automation designed by Nkawie SHTS. It controls home appliances with a smartphone. 

The project consists of a 4 in 1 relay, Node MCU (has embedded wifi), an android app and Led indicators for power input.


6. Students of the Armed Forces SHTS also designed IoT Home Automation and this device controls electrical gadgets with a mobile app. 

The project consists of; mobile app, wifi module 8266, connecting wires, relay, load, transformer, capacitor, and resistors.
