Physics assignment for 2007 T1

Reminder - Physics Assignment
1. u need to prepare a 3-min presentation (15 marks) and an A4-sized poster (5 marks)
2. if u have lost your physics assignment handout, download it at http://d.1asphost.com/angjl/deyi.htm under "Physics WOW! [Show & Tell] ".
3. individual presentations will be arranged in 2nd and 3rd weeks of term 1.
4. Your physics journal (blog):

• is to allow u to keep an online record of your thoughts/questions/online reseach of things related to physics for 2007
• is to help u to collate resources/thoughts/questions for your physics assignments
• will not be graded

Physics Assignment Topics - some suggestions
1. physics in satellite imaging and analysis (electromagnetic waves, satellite launching, sensors)
2. volcanic activity sensing and prediction (sensors, waves, earthquakes, tsunamis)
3. should Indonesia seriously consider nuclear power, and what are the implications for Singapore? (radioactivity, nuclear power generation, volcanic activity & nuclear power stations)
4. haze detection and monitoring (science of particle detection, different haze scales)
5. the poisoning of an ex-Russian spy (hazards of radioisotopes to humans)
6. radiation in cigarettes (Straits Times 2 Dec)
7. Asian Games 2006 at Doha (Straits Times 2 Dec - Macau table-tennis team disqualified due to illegal amt of glue on bats, which will affect spin & speed of ball; S'pore rower Elsie Lim just received her new boat which is more streamlined than her old, so added speed in water;
8. power failure in Chicago

hi 308 & 309,
309 is doing very well, about 19 blogs have been set up...
308 has a long way to catch up!
there are many exciting blogs and postings. not nec must be related to physics.
its a way to share thoughts, observations, exciting websites, online games, etc.
post your general questions about the physics assignment here.

busy lately, give me some time to upload new blogs, and have a happy online time :-)
