The results for the Pedal Predictions are in. I can't believe how close the actual results were to your hypotheses! The task was to predict (for four different gears) how many pedals it would take for my bike to travel across the school (approximately 468 feet). You had to make this prediction without moving the bike. The top 6 groups did not "miss" by more than one rotation of a pedal for any of the four gears. That's amazing, unless one of you broke into the school, stole my bike, and tested it out for real. I might have to check the cameras. Congratulations, learners. See THE RESULTS for yourselves.

I think the most important thing is knowing how far one pedal will get you
Being accurate in all your measurements and knowing what you are doing.
Bailey M.
Easily the most important thing was knowing the cirumference of the tire.
The math and the process was the most important part in learning this lesson
I think the most important thing is seeing the distance it take for one petal
I think the most important factor is knowing all the measurements and having a good group to help you.
The most important thing was getting the right measurements. If you got the right measurements, it was easer to figure out. You also had to know to do the math correctly.
I believe the most important factor was the multiple different measurements, as if we messes up on any of them, the whole problem could be screwed up.
I think that measuring the bike correctly and the length of the hallway is the best way to figure it out.
I think it was figuring out the math because if you didn't have your math correct you probably didn't win
I think figuring out the distance and all the adding and multiply and dividing to figure out the distance and number pedals.
The circumference of the tires
The work that you do needs to be exact
I think the most important thing about this was the measurement of the bike and how long it is.
The most important factor is difficult to choose. One thing that really advanced our research, if you will, is the ratio of teeth to chain links. From that we found the length of each pedal and how many pedals it would take to get from each end of the hallway.
-Kirsten
We figured out the ratio of teeth to chain links. That was very helpful. From that we figured out the length of each pedal.
The most important part in this project is the measuring
-Adam Clemens
The most important factor was figuring out the measurements of the bike and the distance.
The most important factor in figuring this problem out was having exact calculations and measurements
The importance of this was to estimate how the pedals will move and how many until you get to your destination.
We knew all of the data, but didn't know how to configure it. That was probably the hardest part.
Estimating how hard or easy the petals would move.
It was calculating everything for the chains and everything.
Finding out how any teeth are on the gears.
Counting the teeth on the chain wheels
Counting the gears and the distance per pedal.
Counting the teeth on the gears.
Getting the correct measurements
The distance per pedal for each different chain
the most important thing would be to count the right smount of teeth
I think the most important factor is the distance traveled per pedal by each gear. -Grace
The most important factor to me was the distance traveled on each gear.
I think the most important factor in figuring this out would have to be the distance the tire and gear travels.
Knowing the gear ratio.
Figuring how many times the wheele routates and how big and how fasr the wheele rolls
I think the most important part was knowing how the gears work
The most important part in solving this problem is finding out the equations.
How long the hallway was. It decided what you would divide by
To figure this problem out you have to find out all the right measurements then put them all together.
The most important factor for this experiment would be getting the correct measurements.
To figure out the problem you have to get all the right measuments.
The ratio of the rotation of petal to rotations of tire.
The most important factor for figuring this problem out was probably figuring out the right equation to use.
The distance the bike will go with each pedal. The size of the gears matter also.
I think it would've been more important to get better measurements and use a better formula to find the number of pedals.
For my group it was counting the teeth on the gears.
I think some of the most important factors is to have all of the right measurements and to make sure the hallways are cleared so nobody gets hit by a teacher riding a bike.
I think we needed better measurements and a better formula to get a more accurate measurement
The distance the bike will go with each pedal. The size of the gears matter also.
I think that the most important is to get the right measurements
The most important factor was the equation because you have to have it before the whole thing can fit together. Or the actual bike.
The most important factor in figuring this problem out was knowing what information you were looking for.
I think that the most important factor for figuring out this problem is to measure correctly, and to measure the right things on the parts of the bike.
I think the most important things about thie is how many teeth where on each chai.
I Think the most important factor in figuring this out was the exact measurements of the bike parts and the rounding of answers.
I think the most important factor was having accurate measurements!
The most important factor I believe was the amount of teeth on the gears and chain rings.
I think one of the most important factors is getting the math right and knowing what to do with the information you've gathered.
I think the most important thing in figuring this out is knowing what you are doing
I think the most important factor in figuring this problem out was figuring out you had to use the gear ratios/# of teeth, and be extremely accurate in your measurements.
I think the most important factor was making sure all of the measurements are correct.
The amount of teeth on the gears and chain. Also the correct measurements were important.
I think that finding out all the gear ratios and the length of the bike was quite important.
The most important stuff to know is knowing enough, and knowing how to use your data.
The most important part was figuring out the measuring of all of the different parts of the bicycle.
The most important part of doing all of the measurement s and calculating them to get your answer.
The most important factor I think was getting the correct measuring fir the hallway. If you have everything, but not the measurement of the hallway, it will not be correct.
I think the distance you go is most important.
Everything was important; we used about 10 different numbers and 5 different techniques to get our answers.
I think that the length of the hallway was the most important factor.
Gear ratio and distance in my opinion
The most important factor was the gear ratio or the bike
The size of the gears.
The gear ratio.
Gear ratio
I think the size of the gears!
Gear ratio and distance in my opinion a
I think the most important factor was knowing how far the bike goes in one pedal using each gear and chainring. If you find how many pedals it takes to go 1 foot, then you can find out how many pedals it would take to go down the whole hallway.
I think the most important factor to this activity was trying to find how far one pedal can go for each gear. If you find out how far one pedal can go than you can divide that by how far the distance you're going is and estimate how many pedals it would take to get to that destination.
I think the most important part would be the little teeth on the wheels
I think the most important thing is the size of the gears, the size of the tires and the length of the distance the bike is going.
Figuring out the distance
I think the number of the teeth of in the front I and in the back was the most Important.
