In this teaching unit your students learn how to test a solar still by using sensors with an Arduino microcontroller to measure its efficiency. They calculate the volume percentage of the purified water that is obtained and use different low-cost sensors to analyse the effectiveness of their designs. Depending on their skill level the students either use block programming or text programming.

“Liquid Data” is an interdiciplinary approach showing how physical computing can be integrated into chemistry. The students take on the role of researchers. Using Arduino, they conduct an experiment to determine if there is a relationship between the acidity and the temperature of water.

The teaching unit is taken from the brochure Coding in STEM Education from the topic ‘Microcontrolling the World’.

The students design and build their own boat. They use an Arduino board to control the boat remotely with a smartphone and, using AppInventor, they program a mobile app with different contol systems. “The Remote Captain” is suitable for students from 14-16 years.

The students build and use a glove with a different sensor on each finger. This allows them to carry out different experiments and use the “magic” glove to measure temperature, brightness, humidity etc. All they have to do is to select the desired sensor.
