Thread the string through the bushing, |
Then push the axle through too. |
That will hold the string in without having to tie a knot. |
The vertical uprights are held to the horizontal base of the car by two black friction connectors. |
The top of the car has a hub as a pulley. It is held in the middle by two small bushings and secured on the outside by regular bushings. |
Maybe you would like to try 20. But remember in science experiments change only one variable at a time. |
| Practice a few times to get the string rolled up, pennies at the same
height and back axles on a line. Then let go. Which goes farther?
Pick up the three cars and place then on the same line. Which car gets to 6 inches first? Which cars is faster? |

| Using one car a a time, run three trials each.
How far does it go each time? What is the average? |
| The principal and teachers can do this, too. |
