Why do Leaves Fall?

      In Science today, we watched a movie and discussed why leaves fall.  We learn that the trees stop picking up water, the leaves then can't make sugar for food, so the leaves change colors and they fall off.  Before learning this, I asked the students why they think that leaves fall off trees...

- they like to fall.
- they fall because of the wind.
- they fall because its winter.
- because they are old.
- because its fall and they need to.
- because people swing on trees.
- because they are leaves
- because they turn brown
- because they want to
- they wave, then they come down to the grown in the grass.
- they have to because we jump in them.

- because its fall
- because they are old
