Checkpoint 4 – Cooling down( thermometers)
On checkpoint 4 there will be 3 competitions, and each competition will give 3 points to the winning team. If the other team is very close to the other team
( within 3 degrees or 10 seconds), they will get 2 points.
Checkpoint 5- Half measures( glass estimations)
On checkpoint 5 there are 2 competitions, in which the team must go as close to a certain limit as possible. The team which gets closer gets 5 points, the other team gets 3 points. If the team goes over the limit, then that team fails and gets 0 points. The maximum amount of points a team can get in this checkpoint is 10.
At the last competition there were 10 guestions, which give 2 points each.
Only the quickest team will get the point, wrong answer gives-1 points! Each team can answer the

Physics demonstration 01.03.2017
The physics demonstrations took place on 1 March in the morning at a few places at school. The experiments were divided into 5 checkpoints.
The first checkpoint was related to magnetic interaction between a constant magnet and different types of tubes – a cardboard one and a copper one. The difference of interaction was distinguished and vide- otaped.
At checkpoint # 2 an elecrostatic experiment was shown with a machine, called the Flying stick, that produces a positive charge at its ends. An aluminium foil was first charged with the stick and then the stick repels the foil because of the electrostatic interaction between two positively charged objects. As a result, the aluminium foil can“ fly” above the stick.
At checkpoint # 3 the kinetic properties of warm air from a candle were shown. Due to the warm updraft a“ turbine” above it starts to spin. Another aspect of this experiment was lighting again the candle as soon as it snuffed, using the smoke coming from it.
The next trick at this checkpoint was putting
