science fair project with pmi premiums and zap chronics

[dye rocks :)]

i was woundering if any 1 new and good site for a lot of info on pmi pemiums and zap chronics. plz reply:peace:

[pEnNyWiSdOm225]

you are basing a science fair project arond paintballs?:|

[Jaster]

What kind of info are you looking for about them? How they're made and such? I think you're going to be pretty limited on info. You might have to broaden your topic.

[rokobungi]

ya could do a project comparing breakage at speed (like when you shoot at something) compared to breakage due to pressure applied (like in a hopper or barrel)

get 100 of each split it into groups of 25
and fire the balls at 3 different velocities (say 230 265 and 300)record how many bounce out of each brand.
and then with the last 25 of each get a scale that you can measure the pressure that each ball bursts at.

calculate average pressures for bursting with each brand
and the percentage of balls that burst and get a breakage due to pressure VS. shot breaking efficiency graph written up for each speed and then determine the winner from the average of the effencies.

trust me science teachers like stuff that some real world relevance and mathematics involved.

One problem, the velocity would flucuate.

[rokobungi]

as long as velocity didn't fluctuate too much it shouldn't have too much impact if you want to get really accurate fire all the shots through a chrono

Call nelson, and they will send you a LOT of info on how paint is made.

I gotta suggestion! how about doing your science project on something scientific.

you could easily do one on molecular diffusion, and how important it is to the cells of organisms. it is basically responsible for transporting nutrients across cell membranes that are responsible for carrying out cellular functions such as enzyme productions, cell signaling, differentiation, cell growth, and many other cellular responses. just have two reserviors of water that are connected by a tube with a valve and a semi-permeable membrane (ie filter paper, other filters) have food coloring and table salt (iodinized NaCl) in one reservior and distilled water in the other res with the valve closed and filter in place. open the valve and allow the soln of high solute concentration to flow into the res w/ low concentration. then give some explainations about how cells do this to maintain internal pressure, transport nutrients across. and then you could discuss the fact that their are proteins embedded in the membranes of cells that actively (requiring energy) and passively (using energy from conc. gradients) to allow large particles that would not regularly cross the lipid bilayer in cells.

This pertains to both eukaryotic and prokaryotic cells, but try to focus on one or the other. Eukaryotic would be easier IMO.

Or- recombinant DNA technology, where human genes that code for production of insulin are synthisized using the mRNA of a human cell responsible for production of that enzyme (for insulin, these cells are in pancreas. DNA polymerases and ligases are used to complete the synthesis of the DNA strand that codes for insulin production (- the introns). This DNA (cDNA, aka satellite DNA) is transduced by bacteria (in this case E. coli) and incorporated into the bacterial genome. The cDNA then uses the bacterial "machinery" to produce the insulin enzyme that is fully functional in human cells. This allows the cell to metabolize glucose. This is the way that some insulin is manufactured today for use by people and animals w/ diabetes. (ie Humulin U)

Your science teachers dont want to hear something about paintballs. stick to science. unless you get into the exact physics, including pressure, velocity, linear and rotational force. Only thing is, it will be difficult to produce yourself data that is useful do to the random nature of paintballs.

or, if you really want to do something about paintball, do something like how co2 expands from a liquid to a gas or somethink like that. jeeze, cant people come up with their own science projects these days:rolleyes:

HERE IS AN AWESOME ONE: Do one on how paintballs effect plant growth. Take a few different kinds of paint and plants. Than break the paint over the soil each day 5/10 balls. Record your results. This could show that paintballs are bio degradable. And really do not effect plant growth. Or it could not...

[yakitori]

biodegradable doesnt mean that the paint doenst effect biological organisms. It means that it can be broken down by biological organisms (ie insects, bacteria). biodegredation has nothing to do with plant utilization of degrade paint/shell compounds. Although if the compounds of paint are broken down into forms that can be utilized by plants for growth it may increase plant growth.

if you did something like this, you would have to set dependent and independent variables and have a control group grown in the same conditions (ie water, light(duration and intensity), soil, humidity, etc.) as the plants given paint as nutrients. you could record measured plant growth and put it on a graph to compare the two.

Heck man, you dont even have to use paintballs to do that. Use two different fertilizers and a plant with no fertilizer and show effect of each on plant growth.

good idea yuri!

you may have gotten more help if you posted this in the off topic forum under the homework help thread.

[p8ntba11dude89]

^^man, somebody passed science:P

[plushdragon]

You could do a cooking class and make an eatable paintball salad.

[yakitori]

Sorry about that, I am a biology major so I can take biological science a bit overboard. maybe this is not the proper audience for some of my discussions. Ill tone it down a bit. I was just trying to give the person a "hint" of what science is about. paintballs really arent it. JMO though.

[p8ntba11dude89]

a "hint?", you basically gave him a whole entire project, with fully explained details! (never got around to readin the whole thing:P )

Don't be. If those two great ideas don't help him in him project nothing will. Where the hell were you when I was in school banging my head on a desk trying to thing of a great project....

DyeRocks...I'd listen to him on this one. Forget your project (no offense) and do one of his. He's got a point. Science teachers like science, not paintball. Most science teachers can't relate to paintball for some reason....:laugh:
