At camp I did an experiment to see how fast the water flows at in the Ngamuwahine river. For the experiment I needed a tap measure, ping pong ball and a stopwatch. What I needed to do to complet the project was get the tap measure and measure 10 meters down the river. After that I got the ping pong ball and drop it in to the water when I drooped it I started the stopwatch and stopped it once it got the other person holding the other end of the tap. Me and 2 other boy repeated this 3 time and got the average time to see how fast the river was flowing.
