what’s electrocoagulation?
A simple reaction with powerful results

How can we remove pollutants from water without relying on chemicals or filters?
One innovative solution is electrocoagulation.
Here’s how it works:
🔌 Electric current flows through the water
⚙️ Metal ions are released from the electrodes
🌀 These ions help neutralize and bind pollutants together
⏳ The clumped-up pollutants sink or float, making them easy to separate from clean water
see it happen with the makewater kit
In Lesson 1: The Science of Electrocoagulation, students get hands-on experience with this powerful process.
The activity is safe, hands-on, and aligned with key STEM skills, blending chemistry with environmental science, conservation robotics through the use of the micro:bit.
By the end of the lesson, students won’t just understand electrocoagulation, they’ll see how science can solve real-world problems.
why is it great for students?
It’s visual – Students can watch the transformation as murky, polluted water begins to clear.
It’s hands-on
It’s real-world
It sparks questions
