Physics in Advent - Register now for PiA

The popular physics advent calendar "PiA - Physics in Advent" is available again this year. Under the motto "24 more experiments until Christmas", it again offers 24 entertaining physics experiments to try out. Due to the high level of interest from abroad, Physics in Advent is again available in English, as in previous years.

PiA is designed for pupils in grades five to ten and from 11 to 18 years of age. However, based on the experience of previous years, parents, teachers, students or those simply interested in physical phenomena also take great pleasure in it. This year, adults in companies, departments and circles of friends are also encouraged to join in as a team and solve the riddle.

You can watch a simple experiment every day from 1 to 24 December on YouTube, which you can be easily do yourself using standard household materials. Afterwards you will try to explain the phenomena, with four possible answers. The next day, the solution is available - again via YouTube video. If you wish, the results can be evaluated: individually, for a school class or even for whole schools.

The best participants, classes or schools receive prizes. In addition to iPods, books and experiment kits, there are also
