IJSO – Completion of the first round of the olympiad

The first round of the International JuniorScienceOlympiad 2022 is now complete. The students of the IGS examined a wide range of questions relating to the topic of hearing. They learned about the differences between noise, sound and tone, constructed a model of the middle ear and made grains of salt jump and dance with their voices. As in previous years, not only a knowledge of biology, chemistry and physics was required, but also a great deal of curiosity and the spirit of research.
The experiments could be designed using commonly-used household items, so that the students of the IGS could fully participate in the competition even during the online lessons caused by the pandemic.
As in the previous year, some students managed to reach the second round, which will take place in the form of a quiz. The participants of the second round are:

Kelley Kieu My  (Grade 8)
Mayerhofer, Na Na  (Grade 7) 
Tran Thuong Van  (Grade 7)
Tran Viet Ha Mi  (Grade 8)
Vo Thanh Tien  (Grade 7)
Xu, Ziyuan  (Grade 8)

The quiz will be held in March. By Easter it will be clear who has qualified for the third round.
