i need a science project any ideas that relate to snowmobiles i have until may
need a science project
- Thread starter Metallic(a)sled
- Start date
Find out how much drag is in a chaincase... Hook up one end of the chaincase to an electric motor, (a plastic see-through cover on the case would be sweet for the display!) and figure out some kind of way to measure how much power comes out on the driven shaft. Try it with no oil, different kinds of oil (chaincase oil, ATF, some really heavy and sticky oil, engine oil, etc.), maybe even try water just for the heck of it. Get your measurements with all the different situations. Then assign a drag co-efficient to each of the fluids. No oil or fluid would be your starting point of 0.

How many tampons will it take to cross the road and will he make it
Man do we need some snow, sorry Kim couldn't resist..........

You could always measure the fungus in windshield bags and tunnel bags from the buns, hot dogs, beer, trail mix goo left in them all summer.
Might make you throw up in your mouth though.

Research a little bit about metallurgy and explain why making the strongest hardest components is bad because you need a certain degree of ductility in the metal to resist fatigue failure.
Or you could design an experiment that measures the force a given track design places on a fluid body and try to correlate this to acceleration, floatation, traction, whatever
I like LeeDoo's idea the best, it sounds like it could work too. difficult, but would be sweet to find a result. maybe do a project on why ski-doo's blow up so much
Phase 1 - Quantify the benefits or perceived benefits of track porting in terms of weight, rotating mass, snow excavation, floatation and durability/reliability.
Phase 2 - Should phase 1 results indicate track porting has merit - study and present the most optimium hole pattern in terms of: number, size and placement (if you happened to use the Camoplast Challenger in 153" that would be great).

The "real" impact of Sleding?
Ozone?
Enviroment?

I do think LeeDoo's idea is the coolest. If you want to know exactly how to sset up and perform that experiment go to www.crazymtn.com . Mark Hoffman has a series of videos done to show the advantages of the CMX Belt Drive where he uses an electric drill and mointors the electrical load it is under. Do the same thing only exclusively with a chaincase and different lubricants.

You could do a comparison of Testosterone / Stupidity levels while riding under the following conditions:
1. Riding with your buddies.
2. Riding in front of a crowd.
3. Riding in front of a camera.
4. Riding in front of a group of hot chicks.
Unfortunately (not really!! ), my playmate and riding partner is a hot chick with a camera, so I'm $crewed!!

How about making it snow in July.......................
I would even settle for snow say tomarrow ?
On a more serious note, how about testing injection oil Viscosity at differant temps down to below 0. You could test by brand, synthetic, general purpose 2-stroke oil, ETC. This would obviously corralate to the oils performance on that -30 morning cold start !
good luck

What kind of science? What level?
You could buy a cheap microcontroller, and a encoder, and make a display that shows your speed, RPM, ect. Explain how you calculated track speed by the sensor position. You could extend this buy showing EGT temperature, O2 sensor, air density, GPS information, ect.....
You could borrow a IPhone, and use the accelerometers in it, to attempt to calculate track horsepower, and then braking horsepower of your sled. Then lift your sled off the ground and calculate HP loss in your system. This isn't easy BTW.
You could do a 2 stroke engine demonstration, and explain how direct injection works, porting, exhaust valves.
Go take some avalanche classes, and do your own snow pits, measure snow density, photograph slides, and show what caused it. Explain avys.
I like the suggestion, of just showing how a snowmobile transmission works. It wouldn't be too hard to calculate power loss, using a drill motor, and another drill motor (acting as a generator) and show power loss.
Build a avalanche airbag.
Do some jumps with your sled, and show how the suspension works. Calculate how far the suspension collapsed and how much force the springs took. Use a high speed camera.
Collect snow from different depths, and concentrate the dirt in it. Do something about how dark particles are heating the environment. Just don't mention carbon dioxide.
brain dump end. Let me know if you have any questions.

How about the effects of high octane fuel in a lower compression stock sled.

FYI
Science boy is in 10th grade. He loves this site and conversing with you all!! Thank you for all your suggestions! He's excited and mulling them over and will talk them over w/ his dad. (BTW he's pretty smart, loves this "outside the box" stuff) I
I better sneak off here before he "kills" me!

I vote for something fuel or oil related
1. Its cheap
2. Intresting
3. Useful
The transmission would also be intresting

sorry that i haven't answered sooner i've been really busy with math homework and football and yes i'm in 10th grade and i like to think that i'm fairly smart
10th grade...... how about coming up with pollution comparisons of sleds vs. other uses? It would mostly be a statistical research, but it would be interesting to compare it to other vehicles, industrial uses... including time of use per year would allow you to compare on yearly net emissions... You could even try and compare it to ski resorts since it would be easy to find the amount of skiers per day at most resorts....
This has probably been done, but what hasn't these days. It would be cheap, requiring only time.... and internet access.
I am not sure if this is science related enough as there would not be much physical stuff to show, just mostly data and plots.... yes I like numbers.....
Just remember, GIGO.... (Garbage in garbage out) bad data makes the whole argument worthless, and to always spell out every assumption you are making....
