No+Air

__The Problem:__ How do plants respond to variation in amount of air?
 * __Plant Investigation__ **

__Materials:__ 2 Ice cream buckets, 3 water bottles with one way water type of thing, 6 seeds, 4 pots. __Procedure:__ 1. Drill hole on the top of ice cream bucket 2. Fill water bottle with water and put it on the ice cream bucket 3. Fill pot with soil 4. Put seed in pot 5. Put ice cream bucket on pot 6. Take observations __Hypothesis:__ Our hypothesis is that the plant without air is not even going to sprout because __Variables:__ a. Manipulated: __Amount of air__ b. Responding__: amount of growth(height) __ c. Controlled__: type of seed, amount of soil, amount of water, amount of space, time between observations, # of seeds in each pot.__
