Young inventors and researchers are curious, and question everything. How does the staircases light turn on? Why does it go on at the bottom, and back off again at the top? Children learn the answers to these and other questions in a fun way through our Class Set Electrical Control based on nine models and 25 experiments. The set teaches all about electrical circuits using simple applications in a way kids can understand. The models are easy to build in the classroom and integrate with fully designed tasks and solutions. A class set contains 16 individual sets and is suitable for 30 pupils and one teacher, for example.
