Viktiga Datum för IYPT Sverige 2014-2015

18 dec – Datum för att skicka in abstrakt

Eleverna uppmanas att titta på exempelabstraktet (Abstract example IYPT). Uppgifter om hur du skicka in ditt abstrakt kommer senare. Vi meddelar skolor om vilka som får deltar senast vecka 3.

7 feb 2015 – preliminärt datum för nationella uttagningen blir lördag den 7/2. Lokal meddelas senare.

6-12 apr 2015 – Forskarvecka och slututtagning med placering i Malmö/Lund planeras pågå under delar av påsklovet.

8-12 juni 2015 – Sommarskola för åk 1 och 2 planeras till vecka 24 på Malmö Borgarskola.

27 jun – 4 juli 2015 – Final i Thailand

Grattis till ännu en bronsmedalj

Grattis till landslaget som tog hem bronsmedaljer i 2014 års turnering. Laget som kom på en hedrande 11:e plats bestod av

Fransiska Aspegrén
Jakob Hellman
Daniel Jacobsson
Sabrina Wang
Alexander Åkesson

Ett stort tack till alla som bidrog. Ett särskilt tack till Jakob L, Felicia, Patrick, Lars Gislén, Damir och sist med inte minst, Kim.

Uttagning 9 feb 2014

Först och främst ett stort tack till alla som deltog idag.  Följande 10 personer till final final som ska äga rum senare under våren (listan är i alfabetisk ordning).

Alexander Åkesson (Malmö Borgarskola)
Arvid Wendel (Katedralskolan Lund)
Jakob Helman (Malmö Borgarskola)
Lars Åström (Malmö Borgarskola)
Molly Liljebjörn Rusk (Katedralskola Lund)
Malte Larsson (Malmö Borgarskola)
Mattias Sjö (Katedralskolan Lund)
Sarah Tovatt (Danderyds gymnasium)
Sabrina Yue Wang (Malmö Borgarskola)
Toomas Liiv (Danderyds gymnasium)

Dessa 10 ska nu får varsitt nytt problem att jobba med under resten av våren.

De andra som deltog ligger på reservlistan men sannolikheten är stor att någon av de första 10 hoppar av… så var beredd på att hoppa in! De andra som deltog var (i alfabetiska ordning)

Anton Bengtsson
Carl Dahl
Christoffer Virkefors
Malte Larsson
Sina Al-Raiss

Ett stort tack till alla domarna som hjälpte till med uttagningen och till Lunds Universitet för att vi fick vara i deras lokaler.

2014 års IYPT uppgifter

Beslutat av IOC 2013-08-01, publicerad den 2013-08-01

1. Invent yourself
It is known that some electrical circuits exhibit chaotic behaviour. Build a simple circuit with such a property, and investigate its behaviour.

2. Hologram
It is argued that a hologram can be hand made by scratching a piece of plastic. Produce such a ‘hologram’ with the letters ‘IYPT’ and investigate how it works.

3. Twisted rope
Hold a rope and twist one end of it. At some point the rope will form a helix or a loop. Investigate and explain the phenomenon.

4. Ball sound
When two hard steel balls, or similar, are brought gently into contact with each other, an unusual ‘chirping’ sound may be produced. Investigate and explain the nature of the sound.

5. Loaded hoop
Fasten a small weight to the inside of a hoop and set the hoop in motion by giving it an initial push. Investigate the hoop’s motion.

6. Bubble crystal
A large number of very small, similar air bubbles float on the surface of a soapy liquid. The bubbles will arrange themselves into a regular pattern similar to a crystalline lattice. Propose a method to obtain bubbles of a consistent size, and investigate the formation of such a bubble crystal.

7. Pot-in-pot refrigerator
The ‘pot-in-pot refrigerator’ is a device that keeps food cool using the principle of evaporative cooling. It consists of a pot placed inside a bigger pot with the space between them filled with a wet porous material, e.g. sand. How might one achieve the best cooling effect?

8. Freezing droplets
Place a water droplet on a plate cooled down to around -20 °C. As it freezes, the shape of the droplet may become cone-like with a sharp top. Investigate this effect.

9. Water bombs
Some students are ineffective in water balloon fights as the balloons they throw rebound without bursting. Investigate the motion, deformation, and rebound of a balloon filled with fluid. Under what circumstances does the balloon burst?

10. Coefficient of diffusion
Using a microscope, observe the Brownian motion of a particle of the order of micrometre in size. Investigate how the coefficient of diffusion depends on the size and shape of the particle.

11. Candle Power Plant
Design a device that converts the heat of a candle flame into electrical energy. Investigate how different aspects of the device affect its efficiency.

12. Cold balloon
As air escapes from an inflated rubber balloon, its surface becomes cooler to the touch. Investigate the parameters that affect this cooling. What is the temperature of various parts of the balloon as a function of relevant parameters?

13. Rotating saddle
A ball is placed in the middle of a rotating saddle. Investigate its dynamics and explain the conditions under which the ball does not fall off the saddle.

14. Rubber motor
A twisted rubber band stores energy and can be used to power a model aircraft for example. Investigate the properties of such an energy source and how its power output changes with time.

15. Oil stars
If a thick layer of a viscous fluid (e.g. silicone oil) is vibrated vertically in a circular reservoir, symmetrical standing waves can be observed. How many lines of symmetry are there in such wave patterns? Investigate and explain the shape and behaviour of the patterns.

16. Magnetic brakes
When a strong magnet falls down a non-ferromagnetic metal tube, it will experience a retarding force. Investigate the phenomenon.

17. Chocolate hysteresis
Chocolate appears to be a solid material at room temperature but melts when heated to around body temperature. When cooled down again, it often stays melted even at room temperature. Investigate the temperature range over which chocolate can exist in both melted and ‘solid’ states and its dependence on relevant parameters.
