what topic should i chose for my physics project-class 12 on which an experiment can be conducted?

electromagnetic or magnetic fields. It is easiest to research and to do the practical of. Just place the magnets and use iron filings to measure it

Depends a bit on what grade you're in.  I'm gonna guess that since this assignment is about measurement in experiments, you're at a pretty basic level in science.\n\nA pendulum is a great thing for doing experiments involving measuring.  All you need is two or three small weights of different masses, a piece of string to tie them to, and a fixed point from which to hang it and let it swing.  With this you can do experiments measuring distance, time and mass.  Does the pendulum's period (the time it takes to swing back and forth once) change as the length of the swing shortens?  Does it change if you change the mass of the weight?  How about the length of the string?  Or, measure how long it takes to go from one swing length (say, 6 inches) to almost standing still (about 1/4 inch for the cutoff).  Does this change with the length of the string, or the mass of the weight?\n\nYou could have a whole table of measurements of the different factors (length of swing, length of string, mass of weight) and determine wich factors are constant and which are variable.\n\n\nA similar experiment is the one where Galileo tested to see if a heavier object actually falls faster than a lighter one.  The old story is that he dropped balls of different weights off the Tower of Pisa.  But what he actually did, is he took balls that were the same size but different weights and rolled them down a ramp, and timed them to see how fast they rolled down.  Can you figure out why he did it this way, and didn't just drop weights from a height?\n\nGood luck!

this experiment is called calorimetry

see how much weight each surface can hold up. I know u can keep a needle afloat in a cup of water. Although the experiment would depend on what kind of paper and how damp it was.

I would suggest the rock cycle. This is a basic earth science project that you can make as simple or complex as you want. You can identify the three major parts and how they interact going from one part of the cycle to another. You can identify the different properties of these rocks (and find samples if you want). If you want to make it really elaborate, you can bring in how plate tectonics drives the rock cycle, and how volcanism, metamorphism, and sedimentation form the Earth's surfaces.\n\nAnother topic that might be interesting to you would be to identify all the products and materials around you that come from rocks and minerals. Since this includes almost everything (e.g gypsum wallboard, clay in ceramics, iron in cars, aluminum in beverage containers and cars, plastic made from oil, shampoo made from oil, household detergent made from oil, electricity made from burning coal and natural gas, salt on your table, etc). You could look for the most surprising things, and could perhaps include how soil is made from weathered rock so even trees and plants come from rocks. You can do some research on how each of these materials is mined and where it comes from. You get the idea, right? \n\nDepending on where you live, you might do something on natural hazards in your area.If you have earthquakes you could find a fault map for your area and research earthquake hazards. If you have landslides or coastal erosion you could research what causes these things. Of course, if you live next to a volcano that is an excellent topic.  For example, see if you can find an eruption hazard map.  You might want to make sure your teacher approved of this because it might not be within the scope of your class (some teachers might consider this geography more than earth science). \n\nJust a bunch of ideas from a geologist. Hope this helps.

Great idea.  What is your hypothesis?  What experiment will you do?  What data will you collect?  How will you interpret it?

Hi!  This has been my fav. site when it came to doing science projects so far.  http://www.stevespanglerscience.com/index.php\nRemember to call your local papers and have a write up done on it so you have a good turn out for the crowd.  Good luck!

I would have to say physics, especially for a theoreticist.. If you ask me, physics has a purity to it that is not present in anything called engineering...

What are you supposed to model?  Is this a science project?  Do you need to choose something to do?  Or do you have a specific idea you're supposed to explain?

May b u cud try something from a post office box. Its simple as its based on wheat stone bridge.\n\nOr may be u cud study effect of frequency on reactance of inductor/capacitor. \n\nThese r easy and all viva is from theory only. No need to study extra...\n\ngud luck for ur boards.\n\n\nthere is nothing like 'good level'. u cud pick up any topic, even the simplest 1 n make a gr8 project out of it. some more suggestions - time period of physical pendulum, obtaining points where b=0 for various magnets etc. dont u hav enough lab manuals, friends to give u details. ask ur teachers they will help u.\n\n\naur waise bhi yaar, just chill, if u dont make ur proj ur school will surely make 1 for u. after all its reputation is at stake

Physics! It's much more math centric, and more fun then chemistry!  Good luck.
