1. Misty<\/b>
\nInvent and construct a device that would allow the size of a droplet of a mist to be determined using a sound generator.<\/p>\n
2. Stubborn ice<\/b>
\nPut a piece of ice (e.g. an ice cube) into a container filled with vegetable oil. Observe its motion and make a quantitative description of its dynamics.<\/p>\n
3. Electric pendulum<\/b>
\nUse a thread to suspend a suitable ball between the plates of a capacitor. When the plates are charged the ball will start to oscillate. What does the period of the oscillations depend on?<\/p>\n
4. Dusty blot<\/b>
\nDescribe and explain the dynamics of the patterns you observe when some dry dust (e.g. coffee powder or flour) is poured onto a water surface. Study the dependence of the observed phenomena on the relevant parameters.<\/p>\n
5. Sea-shell<\/b>
\nWhen you put a sea-shell to your ear you can hear \u2018the sea\u2019. Study the nature and the characteristics of the sound.<\/p>\n
6. Seebeck effect<\/b>
\nTwo long metal strips are bent into the form of an arc and are joined at both ends. One end is then heated. What are the conditions under which a magnetic needle placed between the strips shows maximum deviation?<\/p>\n
7. Coin<\/b>
\nStand a coin on its edge upon a horizontal surface. Gently spin the coin and investigate the resulting motion as it settles.<\/p>\n
8. Pebble skipping<\/b>
\nIt is possible to throw a flat pebble in such a way that it can bounce across a water surface. What conditions must be satisfied for this phenomenon to occur?<\/p>\n
9. Flow<\/b>
\nUsing a dc source, investigate how the resistance between two metallic wires dipped into flowing water (or water solution) depends upon the speed and direction of the flow.<\/p>\n
10. Two chimneys<\/b>
\nTwo chimneys stand on a box with one transparent side. Under each chimney there is a candle. A short period after the candles are lit one flame becomes unstable. Examine the case and present your own theory of what is happening.<\/p>\n
11. String telephone<\/b>
\nHow do the intensity of sound transmitted along a string telephone, and the quality of communication between the transmitter and receiver, depend upon the distance, tension in the line and other parameters? Design an optimal system.<\/p>\n
12. Kundt\u2019s Tube<\/b>
\nIn a \u2018Kundt\u2019s Tube\u2019 type of experiment the standing waves produced can be made visible using a fine powder. A closer look at the experiment reveals that the regions of powder have a sub-structure. Investigate its nature.<\/p>\n
13. Egg White<\/b>
\nWhite light appears red when it is transmitted through a slice of boiled egg white. Investigate and explain this phenomenon. Find other similar examples.<\/p>\n
14. Fountain<\/b>
\nConstruct a fountain with a 1 m \u2018head of water\u2019. Optimise the other parameters of the fountain to gain the maximum jet height by varying the parameters of the tube and by using different water solutions.<\/p>\n
15. Brazil Nut Effect<\/b>
\nWhen a granular mixture is shaken the larger particles may end up above the smaller ones. Investigate and explain this phenomenon. Under what conditions can the opposite distribution be obtained?<\/p>\n
16. Small Fields<\/b>
\nConstruct a device based upon a compass needle and use your device to measure the Earth\u2019s magnetic field.<\/p>\n
17. Didgeridoo<\/b>
\nThe \u2018didgeridoo\u2019 is a simple wind instrument traditionally made by the Australian Aborigines from a hollowed-out log. It is, however, a remarkable instrument because of the wide variety of timbres that it produces. Investigate the nature of the sounds that can be produced and how they are formed.<\/p>\n","protected":false},"excerpt":{"rendered":"
