First, we found a quarter, a feather, a timer and a ruler.
Second, we use the ruler and drop the quarter and feather at a same height, and than we use the timer test out the speed from quarter fall down and feather fall down.
Third, we will write down all the result, and than make a chart for it.
Those result are :
Height : 12in. 22.in 30in.
Feather : 1sec. 1sec. 1.5sec.
Qurter : 0.5sec. 0.7sec. 0.9sec.
