I'm especially excited about this because it includes a photo of the little pre-K science project my class did. As the photos scroll, look for the one that says "Float or Sink," made out of bread. It's brief, but it's there!
There are times when pre-K can feel like a bit of an afterthought in an elementary school, and it made my day to see that our work was included in our submission to the NASA site. Yippee for us!
It was a really fun experiment, too. Big, airy slices of bread (low density) float on the surface of the water, but if 4-year-olds mash up that bread into tight little balls (high density), then lo and behold, they sink! Good times.
