Using the same three airplanes we tossed along a string inside the classroom on the first day, we were curious to know if we'd get the same results outside. So on day 2 we went outside.
We quickly noticed a heavy breeze on the grass so decided to move next to the portables which blocked most of the breeze. The teacher tossed the first trial and sure enough the smallest plane flew the shortest distance unlike the results for the smallest plane inside the classroom. We discussed why the same experiment outside had a different result. The students decided the wind or breeze as the unexpected and uncontrolled variable which influenced the smaller plane.
Then each child took their three tosses to see if we all had the similar results. In 9 out of 10 trials, the smallest plane either flew the shortest or tied with the largest plane.
Once the outside and inside data was recorded and compared, the children were asked to make a Doodlcast video & explain the differences - Enjoy !
