what are sprouts?

While making our lap books Pitty-pat asked me what the sprouts were that jesse bear had for lunch. I found this science in a bag idea from http://www.preschoolexpress.com/ that explains how to grow your own sprouts in detail  easy peasy

SCIENCE IN A BAG
SPROUTING SPROUTS
Day 1:
Take a small zip-lock bag and using a needle, punch a few holes in the bottom seam of the bag.
Set out a bowl of seeds, and have your child place a teaspoon of seeds in a bag. Alfalfa or mung bean seeds work best.
Zip the bag closed and have your child place the bag in a bowl of warm water.
Soak the seeds overnight.
Day 2:
The next day, have your child take the bag out of the water and let it drain, then let it sit in indirect sunlight the rest of the day.
Day 3:
For the next few days, have your child dunk their bag in water for a few seconds, then drain and again set in indirect light.
Day 4:
On the fourth day, have your child set the seeds in the sun.
Day 5:
Have children watch the sprouts turn green.
These sprouts can be eaten by sprinkling them on top of a green salad or on top of cream cheese spread on crackers.
I am going to try this with Pitty-pat and Tippy-toe. We may not have a book store but we do have  three health food stores in a ten mile radius. I wish we had planned ahead and started this earlier.
