Coding H2O - How to program a solar still

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.

The teaching unit


The Remote Captain

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 teaching unit is taken from the brochure Coding in STEM Education from the topic ‘Microcontrolling the world’. The complete brochure can be


Discover natural scientific phenomena in the Kitchen (Lilu’s House)


Which sort of bread do people eat in foreign countries? Why do you need yeast to make dough rise? Where is our numeral system from? With simple bread recipes children explore new culinary traditions and languages of other countries as well as the physics of yeast-dough. The kitchen offers children various opportunities for inquiry-based learning while simultaneously training their skills in speaking,


Discover natural scientific phenomena in the bathroom (Lilu’s House)


Why does the mirror fog up when you take a shower? Why do you see your reflection not upside-down in a shower head as you would in a spoon? And why is clean water coming out of the tap even though it comes from the ground?

From codensation to the reflection of light to the circulation of water - there are plenty of scientific phenomena to discover in a bathroom! This teaching unit offers children various
