自然科學實驗-飛行的最好形狀


4/21,2011




Kindergarten is trying to find the best design for a paper airplane and testing their abilities at Cheng Gong Park.






Look how far it went. I can see it on the mountain.






That airplane did not fly very far did it!





 Whose airplane went farthest?






Taking a rest, because flying airplanes is hard work.






  The strings are helping to show the air flowing past the planes.
