SR is 6, and in first grade. With the help of his Science mentor, he prepared, researched, and learned about the water cycle and was able to present it to his first grade classmates. (I was in Tacoma, so DH was gracious enough to film it!)
Not too bad for his first time out of the gate.
PN makes an appearance, but you can hear her through the entire presentation. She got a stern lecture from her Father on the arrival back home.
