Air

__The Problem:__ How do plants respond to variation in amount of air? __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 __Materials: 2 Ice cream buckets, 3 water bottles with one way water type of thing, 6 seeds, 4 pots.__ __Variables:__ a. Manipulated: __Amount of air__ b. Responding__: amount of growth(height) __
 * __Plant Investigation__ **

c. Controlled__: type of seed, amount of soil, amount of water, amount of space, time between observations, # of seeds in each pot.__

__Observations/Logbook:__ __ Day 1: Date: not germinated

__ Day 3: Date: not germinated

__ Day 5: Date:#1 and 2 no air sprouted, air not sprout

__ Day 7: Date: __No air #1 approximately 17 cm No air #2 approximately 12 cm Air #1 approximately 6 cm__

__ Day 9: Date: Today the plants are doing fine they are going strong and they have leafs. no air one is about 17cm no air two is about 12 cm and air 1 is about 6 cm our plants have not yet grown in the last 3 days air 2 has been over water and is drowned completely we have dumped it into the garbage. __ Day 11: Date: today all of our plants have been drowned except for one. the no air plants, people have been watering them for no reason. no air 1 is brown water and at the top you can even see clear water. no air 2 is like brown water to.

__ Day 13: Date: today i have noticed that the plants are growing into the bottle and curling up like a ball in the water bottle. so today we have dumped the plants ( the no air plants ) and we are hoping we can replant soon. the fact that the plant is curled in a ball in the water bottle i have not been able to take the measurements.

__ Day 15: Date: today we still have no plants except for one the air 1. Which has been knocked over i couple of days ago.
