International Junior Science Olympiad
The International Junior Science Olympiad (IJSO) is an annual science competition for students aged 15 and under. It is one of International Science Olympiads and the only international academical competition that covers physics, chemistry and biology at the same time. The first IJSO was held in Jakarta, Indonesia in 2004. Around 70 countries send delegations of three to six students, plus one to three team leaders, and observers.http://www.ijsoweb.org/qna/ijso_statutes_08112019.pdf The competition is broken down into three tests, each of which lasts between three and four hours. The theoretical portion consists of two tests: a multiple choice questionnaire consisting of 30 questions, and a theoretical test. The practical portion consists of three laboratory examinations, one for each field. Incidents Because of COVID-19, the 17th International Junior Science Olympiad 2020, originally planned to be held in Frankfurt, Germany, was cancelled. Due to the COVID-19 pandemic, the 1 ...

Silver Medal 4th IJSO
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures.
