On Monday Piwakawaka did an experiment about wind vanes first we started off by getting a tray of materials. in the tray was a square piece of paper, straw, cup and play dough then we started by writing down North,East,South and West on our paper
Next we got our straw and cut down a split on both sides. So the triangle and square could fit.
After that we got a pencil and stabbed it in our cup and put our pencil through the cup then we got our playdough and put it under the cup so it can be stabled.
Lastly we got our pin and poked it through the straw and to make it touch the rubber then we went outside to test our wind vane. but when we went outside there was no wind so we just came back inside hoping that it would work next time. in the mean time they were using the fan to make the wind vane move
