well.. so this didn't turn out quite as I had expected.. I was hoping for a relieving gasssssp of air as the air hole in the 5 gallon water jug was opened. At the very least, I'd have liked to have heard some Glub-glubs at the start of the movie before the air hole was opened. No dice on either.
I will have to repeat this film experiment when the water jug is full again.

Plants respond behaviorally to changes in their environment by changing patterns of growth. The purpose of this lab is to explore how environmental features like light and volume of air influence growth in mung bean sprouts. Students will make predictions about the relationship between growth and environment, and test their predictions by growing sprouts in various sized plastic soda bottles.-Any Lab Test Now Franchise
