"Wheelie" experiment

Here, we're gluing the wheels on to the axel
As a part of our Simple Machines unit, today we create a wheel and axel with a toilet paper roll and two circles cut from cereal boxes. We got to choose what type of experiment we did (to test a theory). For example, some students tried to make the wheelie goes as far as it could, or people changed the location of the axel to see how that would affect the way it moved. Some students chose to use bigger wheels, and some used smaller wheels.

Here were our steps:


Why we did this experiment:
"To see what type of wheels would go farther than other types of wheels." ~ Owen
"To experiment how we make toys and how if it's heavier or lighter will make it faster." ~ Sophia
"We've been learning about Simple Machines and this is a type of simple machine." ~ Priya
"For problem-solving." ~ K

"This was my original design of a wheel and axel." ~ Jaxton


What we learned
:
"I learned that the bigger the wheel, the less friction it makes, so the faster it goes." ~ Nikita
"I found extra pieces of cardboard. I made an extra air pocket to catch the air. I learned that it will slow the wheel and axel down." ~ Owen
"I figured out that when you attach more wheels, it stabilizes it. As it goes down the incline plane, it slows it down which makes it roll straighter, and helps it go farther." ~ Jaxton

This is where we tested our wheelies down the ramp/incline plane.
