IYPT is an international physics competition for upper secondary school students and is based on open research on the 17 problems published about one year before the tournament annually. Students work on the questions in groups of 5, and present their solution during the competition and get involved with discussions in which they defend their own solutions and criticize others solutions in structured discussions.

#3. Steel Balls

Steel Balls

Colliding two large steel balls with a thin sheet of material (e.g. paper) in between may burn a hole in the sheet. Investigate this effect for various materials.

#8. Liquid Light Guide

Liquid Light Guide

A transparent vessel is filled with a liquid (e.g. water). A jet flows out of the vessel. A light sorce is placed so that a horizontal beam enters the liquid jet. Under what conditions does the jet operate like a light guide?


Here is a selection of the 22nd IYPT solutions and presentation slides of the team of Iran. These solutions were obtained of long term investigations in group work which include several experiment, theories, numerical solutions in some cases and etc.

Note that the slides were produced to be presented in twelve minuets, so a limited amount of information could have been included.
