Measuring Car Speeds

Today the students went outside to measure the speed of the cars. Students were placed in groups of three. One student would be the marker, one the writer and one the time keeper. One of the students would stand at one end of 25 metres and signal start. The other two students, which would be standing at the other end of the 25 metres would stop the watch when the car or truck went past the 25 metre mark. The time would be marked down. The students then went back into class and made a graph of the times.
