Title: Skateboard Lab
Procedure:
After dividing into two groups, we volunteered ourselves for the following jobs: Timer, (7) skateboard rider, (me) data collector, (1) and pusher (1). we drew chalk lines on the pavement exactly two meters apart on a down slant of approximately 10-15 degrees. Each timer stands with their stop watch a one of the chalk lines so that all seven of them are at a line. The skateboarder then sits on the board so as to stay balanced behind the first line. The pusher then pushed the skateboarder ever so slightly so as to not make him/her accelerate too fast. After the front of the skateboard passes each chalk line, that timer will stop. The data collector will then record all of the times that the timers have. Repeat this procedure multiple times to obtain more accurate data.

No need to say divide into two groups
no need to say what you specifically did
begin by drawing a start line on a hill, then the rest of the lines straight down the hill every 2 m.
stopwatch
at one of the chalk lines
all seven timers (I think there were only six?) are at a line.
call the first line the start line
what about starting the stopwatches?
as soon as the front of the skateboard
stop their stopwatch
in what order do you collect the data?
be specific- repeat for a total of three complete trials.
