In this activity, you will…

3
00:00:06.432 --> 00:00:09.915
Explain why leaves look green and why some change color in fall.

4
00:00:10.235 --> 00:00:13.950
Use leaf and plant photos to ask AI and check its guess.

5
00:00:14.270 --> 00:00:18.868
Identify the leaf shape and vein clues AI can compare in a photo.

6
00:00:20.068 --> 00:00:22.529
With your grown-up, watch two short videos.

7
00:00:22.849 --> 00:00:24.846

00:00:27.994 --> 00:00:31.477
Scan the codes in your workbook, or find the links below this video.

10
00:00:31.677 --> 00:00:36.506
Look and listen for clues! Pause now, and come back when you’re done.

11
00:00:44.156 --> 00:00:46.432
Welcome back! Why are leaves green?

12
00:00:53.032 --> 00:00:54.982
Turn your page upside down to check!

13
00:00:55.302 --> 00:01:00.457
Leaves have a green helper called chlorophyll. It uses sunlight to make food for the tree.

14
00:01:01.657 --> 00:01:03.747
And why do leaves change color in fall?

15
00:01:10.347 --> 00:01:14.852
In fall, leaves stop making green. Then yellow and orange show.

16
00:01:16.052 --> 00:01:19.256
So the yellow and orange were hiding there all along!
