SYPT

Das Swiss Young Physicists' Tournament (SYPT) ist ein schweizweiter Wettbewerb, an dem physikbegeisterte Schülerinnen und Schüler aus der ganzen Schweiz teilnehmen. In einer Vorbereitungsphase wird eine kleine Forschungsarbeit gemacht, welche am eigentlichen Turnier präsentiert und verteidigt wird.

Aktuelle Forschungsarbeiten

Im Schuljahr 2018/2019 wurden an unserer Schule 12 SYPT-Themen bearbeitet:

4. Funnel and Ball 

A light ball (e.g. ping-pong ball) can be picked up with a funnel by blowing air through it. Explain the phenomenon and investigate the relevant parameters.

Bearbeitet von Parthiv Kangsabanik (1a) 

5. Filling Up a Bottle

When a vertical water jet enters a bottle, sound may be produced, and, as the bottle is filled up, the properties of the sound may change. Investigate how relevant parameters of the system such as speed and dimensions of the jet, size and shape of the bottle or water temperature affect the sound.

6. Hurricane Balls

Two steel balls that are joined together can be spun at incredibly high frequency by first spinning them by hand and then blowing on them through a tube, e.g. a drinking straw. Explain and investigate this phenomenon.

Bearbeitet von Elio Jucker (1a)

7. Loud Voices

A simple cone-shaped or horn-shaped object can be used to optimise the transfer of the human voice to a remote listener. Investigate how the resulting acoustic output depends on relevant parameters such as the shape, size, and material of the cone.

Bearbeitet von Fiona Kutschke (1a) & Hannah Peters (1a)

8. Sci-Fi Sount

Tapping a helical spring can make a sound like a “laser shot” in a science-fiction movie. Investigate and explain this phenomenon.

Bearbeitet von Shria Thiyagarajah (1a)

9. Soy Sauce Optics

Using a laser beam passing through a thin layer (about 200 μm) of soy sauce the thermal lens effect can be observed. Investigate this phenomenon.

Bearbeitet von Moritz Tschudin (4d, Maturaarbeit)

11. Flat Self-Assembly

Put a number of identical hard regular-shaped particles in a flat layer on top of a vibrating plate. Depending on the number of particles per unit area, they may or may not form an ordered crystal-like structure. Investigate the phenomenon.

Bearbeitet von Luca Cannavó (1a) & Felix Miolin

12. Gyroscope Teslameter

A spinning gyroscope made from a conducting, but non- ferromagnetic material slows down when placed in a magnetic field. Investigate how the deceleration depends on relevant parameters

Bearbeitet von Corentin Bezençon (1a)

13. Moiré Thread Counter

When a pattern of closely spaced non-intersecting lines (with transparent gaps in between) is overlaid on a piece of woven fabric, characteristic moiré fringes may be observed. Design an overlay that allows you to measure the thread count of the fabric. Determine the accuracy for simple fabrics (e.g. linen) and investigate if the method is reliable for more complex fabrics (e.g. denim or Oxford cloth).

14 Looping Pendulum

Connect two loads, one heavy and one light, with a string over a horizontal rod and lift up the heavy load by pulling down the light one. Release the light load and it will sweep around the rod, keeping the heavy load from falling to the ground. Investigate this phenomenon.

Bearbeitet von Anshak Mallik (5d)

15. Newton's Cradle

The oscillations of a Newton's cradle will gradually decay until the spheres come to rest. Investigate how the rate of decay of a Newton's cradle depends on relevant parameters such as the number, material, and alignment of the spheres.

 Bearbeitet von Elio Wanner (4d, Maturaarbeit) 

17. Popsicle Chain Reaction

Wooden popsicle sticks can be joined together by slightly bending each of them so that they interlock in a so-called “cobra weave” chain. When such a chain has one of its ends released, the sticks rapidly dislodge, and a wave front travels along the chain. Investigate the phenomenon.
