I was taken aback by the simplicity of this item and thought of all the times I would struggle with understanding the different types of circuits, power sources, electronic gates etc. This was a winner as I soon as I saw it. The simplest kit allows 39 circuits to be built, and the most complex – more than 2000. The price is affordable, and allows children to understand solar power, hand generators and many other options. Please get in touch if you agree that this would make a difference to your students.
