| ...blowing over the paper creates lift... |
During the last few days we have been working on another science inquiry: How do you achieve lift without heating air? Here are some experiments we have been doing.

| he's got it! |
 |
| What about blowing through a tent? |
 |
| We blew on blue paper |
 |
| This is an "uplifting" experience! |
 |
| They didn't move! |
We also created cones from a circle with a radius of 9cm, cut a hole in the bottom, placed a ping pong ball in it and tried with all our might to blow it out of the cone. IT DIDN'T WORK!
 |
| ...blow as hard as you can... |
 |
| No matter what... |
 |
| ...girl... |
 |
| ...or boy! |
 |
| David couldn't do it either! |
Why, you might ask! BERNOULLI'S PRINCIPLE, that's why! Ask your child about it and watch the short video together below as a good review.
Next, using the properties of air that we have learned about and Bernoulli's Principle, the students were asked to create and test flying devices using materials provided. There were three "airports" with different tests to perform. The results varied widely.
Up next: science evaluations. How well can you apply these principles to a paper airplane?
