What do students do?
Vicphysics Teachers’ Network established a competition for Year 10 Science and Year 11 physics students. In the course of the year, in teams of three, students will carry out three experimental investigations, then later in the year, present and defend their findings in scientific discussions with other teams. They also critique the presentation of other teams.
The tournament was last conducted in 2017. It will be held again in 2021 on Sunday, 12th September at the University of Melbourne.
The problems for investigation in 2021 are:
- Conical Piles Non-adhesive granular materials can be poured such that they form a cone-like pile. Investigate the parameters that affect the formation of the cone and the angle it makes with the ground.
- Saxon Bowl A bowl with a hole in its base will sink when placed in water. The Saxons used this device for timing purposes. Investigate the parameters that determine the time of sinking
- Falling Tower: Identical discs are stacked one on top of another to form a freestanding tower. The bottom disc can be removed by applying a sudden horizontal force such that the rest of the tower will drop down onto the surface and the tower remains standing. Investigate the phenomenon and determine the conditions that allow the tower to remain standing.
Here are some Guide questions and hints to assist students in getting started.

Is it possible to remove the last block from a the lowest layer of a Jenga tower?. This question was posted on a physics blog. There are a few responses.
How quickly would you have to pull to remove an entire floor in Jenga? This question was posted on a reddit blog. There are a few responses.
Some advice on doing investigations. The document covers planning possible equipment, measuring and analysing data.
University students are available to be a mentor. Ask your teacher to arrange for one. They will be available for two one hour sessions, either face to face or on-line, once after you have got started and later when you are finalising your analysis and preparing your report. They can also respond to any email queries through your teacher.
Tournament Date: Sunday 12th September from 9:00am until 3:30pm.
Physics Dept, University of Melbourne
There will be a trophy for the school of the winning team.
There will book prizes and book vouchers for the members of the top three teams, as well as book vouchers for the members of all other teams.
Videos of the Tournament
At the 2014 Victorian Young Physicists’ Tournament, Terry Tan from John Monash Science School videoed the competition as did some of the other teachers. Terry has edited the footage into two packages, i) a short one using extracts from different contests to show the key features of a contest and ii) a longer one of one complete contest. See links below.
The Vicphysics Committee appreciates the tremendous amount of work by Terry in chasing up school approvals and then editing the material into these packages.
Organisation of a Tournament
Assessment criteria to be used by the judges for VYPT contests. There is a separate criteria sheet for each of the roles of Report and Critique. Teams should read through the criteria to ensure their presentations cover them.
Lunch will be provided as well as morning and afternoon teas.
Each team will compete in six contests, three as presenter and three as opponent. Each member of a team will present on one topic and oppose on another.
Each contest will be judged by a panel of 3 people, which will include at least one teacher. At the end of the contest, the judges are encouraged to ask questions of both teams before each deciding on their scores.
Each contest lasts about 30 minutes. There are specified time limits for different sections within the 30 minutes to ensure comparable judging.
|Activity||Duration in mins|
|Reporter prepares, plugs in laptop, USB etc.||3 min|
|Reporter presents||10 min|
|Opponent asks clarifying questions||2 min|
|Opponent prepares||3 min|
|Opponent critiques for up to 5 minutes, argues with reporter for remainder of the time.||10 min|
|Reporter prepares concluding remarks||1 min|
|Reporter makes concluding remarks||2 min|
|Jury questions and grading||4 min =total 35min|
Advice for teams on conducting a contest will be available by the end of Term 1.
The six contests proceed through the day starting about 9:30am and finishing about 3:30pm.
