Wondering with physics: engage public and teachers in science communication

The European Researchers' Night takes place every year simultaneously in many cities all over Europe and beyond. Researchers and teachers designed and implemented together a series of inquiry-based activities to bring people closer to physics. The enthusiast answer from participants suggests that these activities can be easily utilized with students for enhance their motivation.
