When we were in Year Two, Dai came in to tell us about the Arctic. Now he has gone to Peru in South America. We did research to find out about life in Peru and Dai is emailing us every day. He is going to see the Nazca lines tomorrow. He told us they eat guinea pig in Peru! We decided to do another investigation on falling objects because in our reflection of the parachute investigation we didn't think out results showed a pattern because the timing on the I-pad wasn't accurate enough. This time we had two people timing. We then found the mean of the results and put the results into a graph. It was quite difficult drawing the axes but it gave us the opportunity to use decimals. We could see a pattern in the results and most of us concluded that the largest leaf fell at a slower rate because it had a greater surface area for the upward force to act on! |
