00:00:00,000 --> 00:00:27,600
Today is a great day for flying kites, and that's what we're going to do.

2
00:00:27,600 --> 00:00:33,600
First, we have to build it. Who knows what shape kite we are building today? What kind?

3
00:00:33,600 --> 00:00:37,600
In designing the invention, there are a few fundamental concepts they'll need to understand.

4
00:00:37,600 --> 00:00:40,600
Research what is already known about the idea.

5
00:00:40,600 --> 00:00:43,600
We observed that hawks soar better than buzzards,

6
00:00:43,600 --> 00:00:46,600
and that hawks also maintain their balance in strong winds better than buzzards.

7
00:00:46,600 --> 00:00:50,600
Why? Because their wings are shaped very differently.

8
00:00:50,600 --> 00:00:54,600
The wings of a hawk arch up a little and then flatten at the tip.

9
00:00:54,600 --> 00:00:59,600
A buzzard's wing gradually angles upward all the way to the end.

10
00:00:59,600 --> 00:01:01,600
And then, they'll need to keep a journal.

11
00:01:01,600 --> 00:01:07,600
It is essential for them to keep very careful and accurate records of everything they do on the project.

12
00:01:07,600 --> 00:01:11,600
Hi! My friends don't believe that I met the real Orville and Wilbur Wright,

13
00:01:11,600 --> 00:01:17,600
so could you sign this picture I took of you?

14
00:01:17,600 --> 00:01:22,600
Hey, where'd they go? I know I'm not crazy. I just saw Orville and Wilbur Wright.
