paulmbowers 236 Posted March 4, 2010 Just got the OK from my son's 4th grade teacher to bring my bike into the classroom as a subject for math/science instruction. Should be cool- I want to talk about: Fuel/air ratios- explain a carb and ideal mixture Final drive ratios- how many teeth in the sprocket vs the countershaft expressed as a ratio, then rotate the rear wheel one revolution and count the number of revolutions in the smaller countersprocket fuel capacity and calculate fuel range at two provided mpg- one for street cruising and another for the dirt. traction- slick vs knobby center of gravity- where is the mass of the bike located nature of materials- have a kid whack the tank with a mallet to show plastic does not dent. What other lessons can be taught with a bike as a tool? I can't start it. Share this post Link to post Share on other sites

What other lessons can be taught with a bike as a tool? I can't start it. what about a lesson about bikes with a tool as a teacher? what about geometry? It can be part of the mass centralization... how fore and aft weight reflects the type of riding to be done. rake/trail and how they affect steering Tire diameter/contact patches, and how a bigger tire is better for rolling over stuff what about something regarding the space taken up by a motorcyclist, and how it can positively affect traffic? explain to them why a backflip is much easier than a front flip (for me anyway) Share this post Link to post Share on other sites
Crawdaddy 96 Posted March 4, 2010 What other lessons can be taught with a bike as a tool? Why don't you stick to what you know and show them how to change a tube edit: Whoops, sorry Fakey - I thought the Slutty One posted this...... Share this post Link to post Share on other sites
boat440 0 Posted March 4, 2010 You might want to make a copy of the schematic of your bikes electrical system and hand-out in class. Explain to them what each symbol is and what each part does? Share this post Link to post Share on other sites
TrophyHunter 15 Posted March 5, 2010 Take in an extra wheel if you have it. Mount handles at the axle location. Put 'em in a chair that spins. Hand 'em a spinning wheel and have 'em turn it each direction. They should spin the direction they turn the wheel. Did this with Alexis at the science museum in SF. ....and that's why bikes wanna stay upright while moving. Share this post Link to post Share on other sites
bikeslut 1 Posted March 5, 2010 I can bring you an extra wheel if you want to do that you can also put weights on the spokes... inside the cross pattern and outside... show them how the weight to the outside of the wheel exerts more force... crawdaddy- We are trying to mold the youth of America through a hands on approach to science and motorsports... there is no room here for tomfoolery Share this post Link to post Share on other sites

paulmbowers 236 Posted March 5, 2010 What other lessons can be taught with a bike as a tool? The final lesson of the day, ATGATT. Yeah- theres some question about that. If I completely avoid gear and riding lifestyle, it keeps the lesson in the abstract, safe from the fears of parents that I'm indoctrinating their youngsters into the moto lifestyle. OTOH, it's prudent to bring in all the gear I wear for protection- there is a lot to be learned- and reinforce that motorcycling is a decision to be carefully considered. We'll see. thanks.

Zenosan 2 Posted March 11, 2010 Good show Paul! Did you explain the relationship between a spinning top and why the bike doesn't fall over when rolling? Gyroscope? I have visited my wife's 3rd grade class many times, once with all the protective gear but never with a bike. I even did a swing dance demo for them once. These activities make classroom stuff relevant for the kids. Share this post Link to post Share on other sites
paulmbowers 236 Posted March 11, 2010 Good show Paul! Did you explain the relationship between a spinning top and why the bike doesn't fall over when rolling? Gyroscope? Yes, with those words. And one of the kids made the connection with a spinning top. I expected a lot of wow factor by bringing in the bike, but did not expect it to work so well. I'd ask questions pertaining to fuel consumption on the 3 gallon tank, half dirt, half street, and their minds really took off. Same as final drive- calculate the ratio between a 14 and 49 sprocket, then turn the rear wheel one revolution to determine how many times the front sprocket will turn. Emphasis on the mathematical predictability of mechanical relationships. They GOT it. Share this post Link to post Share on other sites

Wil... don't pay attention to the old hippy... school is VERY relevant to life, in that it gives you choices!
