Jenny+and+Philip's+Air+Amounts

=
Jenny: I think that the plant in jar A which has the open lid and gets the most amount of air will grow the best, as apposed to the plants in jars B and C, which aren’t exposed to air fully. I predict this because to grow and be healthy, plants need to have a balanced amount of air. That means that there has to be just the right amount of oxygen and CO2- so if there is too much CO2, the plant won't be healthy, and eventually die.=====

=
Philip: I think that the plant with the most air (jar A) will grow the most because they need the CO2 in the air to photosynthesis and that is how they product sugar. The sugar is what they use to grow so there for they plant with the most air will grow the biggest.=====

=
c. Controlled: Amount of seeds in each jar, size of jar, amount of water given to plants, same amount of soil, and same soil.=====

__Day 5: Date: October.8/09__ Jenny: Today we discovered that the plant in jar A has sprouted! It's about 1 cm tall. But the plants in jar B and C haven't fully began rising yet. Though we already can see roots from the bottoms of all 3 jars, the seeds haven't yet began growing upward. I think the reason why the plant in jar A sprouted before jar B and C is because jar A has the most air entering it, as apposed to the 2 other jars.=====

=
Philip: Today we found that plant "A" has sprouted it is about one cm tall. Still both other plants haven't sprouted yet but we can see some roots at the bottom of the jar. Jar "A" is growing the fastest i think is because is that it has lots of oxygen unlike jar "B" and "C" which have limited or no air. I also noticed that we are going to have to take the cup of of the top because the plant might grow up to it by the time we come back from fall break.=====

=
Jenny: After not watering our plants for a whole 10 days, Philip and I discovered that plant "A" grew 32 centimeters over the long break. It is pretty yellow on it's stem and leaves -not to mention everywhere else- but I believe that that is because of the shortage of water. I still haven't noticed any changes in Jars B and C, and I figured that the lack of oxygen is why they still have not germinated. I wonder if those 2 plants are dead.... they might even have drowned, because every time I check- the soil is extremely moist, and even seems to not be absorbing the water which we give it. I think that's because the soil has reached it's full absorbency level (it's full of too much water,) and is just being overloaded because oxygen can not enter the jars properly and evaporate the extra water left on the surface of the soil. But meanwhile- the soil in Jar A is staying just fine (cool, damp, chunky-less,) as apposed to the soil in Jars B and C.=====

=
Philip: Today we got back from fall break without watering are plants for 10 days we noticed that plant "A" has grow 32 cm!!! But plant "B" and "C" still haven't sprouted. Also we noticed that jar "B" and "C" are really watery and we didn't water them for 10 days. I think it is because none of the water in those jars can evaporate because the lids are keeping the vapor in. The seed in jar "C" is floating at the top of the water and we think that it is dead and we can not see jar B's seed so i hope that is a good sign.=====

=
Jenny: Today, plant "A" is a whole 35 centimeters. That means that from day 7, it grew 2 centimeters. The 2 other plants ("B" and "C",) still haven't even germinated! In fact, plant "C" is actually floating on top of the water above the soil. The water level in jars A and B have reached so high, that you can see the other side of the room through the murky, brown water if you take a look through the jar. The soil in jar A is staying nice & damp, and the soil in jars B and C is staying not-so-nice & soaking. Although a study has shown that what plants grow in (soil, sand, rocks, gravel, water, etc.) actually doesn't affect the plant. Growing plants in water is called "Hydroponics," so maybe plants "B" and "C" will germinate as hydroponic plants.... (just a thought....) I've also noticed that plant "A" has began to redeem it's green color. I think that's because we watered it. Philip suggested that we do not water the plants every day, because we might over flow jars B and C. I don't agree because we are supposed to water all the plants each 2 days, and suddenly changing the cycle might be harmful to plant "A" which is the one fully exposed to air.=====

=
Philip: Today plant B still hasn't germinated and plant A is now 35 cm's! the plant is still a little bit yellow but is getting better from before. plant C has some white liquid coming out from the seed that is floating in the water. we haven't been watering plant b and c for a while but they are still filled with lots of water. There is a big layer of dirt then a layer of water and another layer of dirt on top of that i think that is happening because all the soil that is heavy is at the bottom and the light soil is floating at the top.=====

__Day 11: Date:__ October.23/09
Jenny: Jar A today is 36 centimeters, but Jars B and C still haven't germinated! I've noticed that plant A is beginning to //slightly// loose color again. I think it's because Philip and I have decided to change the watering routine because plants B and C are practically drowning... so now, we will only water every 3 days instead of 2. As for Jars B and C — the water is evaporating a bit, which is a good sign, meaning that air is flowing into the jar easier. Philip: Jar A is starting to lose its color again but it is now 36 cm's tall. Jar B and C still haven't germinated yet and they are still flooded in water. i think that jar A is really tall compared to all the others in the class because it was in the dark during fall break so it grew up, up, and up to try and reach light and now it is tall and a little yellow.

=
Jenny: Today the plant in Jar A is once again 36 centimeters. I think it didn't grow because Philip and I haven't watered our plants in 3 days. As a result, plant A also changed color by dimming to a slightly yellower shade. The water in Jars B and C is finally starting to fully evaporate, but still Philip and I are keeping our 3-day-watering-routine cup, simply to not change it every time when the results change.===== Philip: Jar A is still 36 cm's jar b and c still haven't germinated so i conclude that they drowned in the water which is flooding the whole jar almost. jar A is still doing ok it hasn't returned to green yet but it is getting there. The water in jar b and c has lowered a little which is good but there is still the layer of water in between two layers of dirt.

__Day 15: Date:__ November.13/09
Jenny: Today I'm just going to talk about each jar in order. Jar A grew 2 centimeters since last time we checked, and it now is a pale green. It's slightly tilting to the side as if broken or bent. I think it is bending because the leaves are beginning to get too heavy on top of the long the stem. I think that the reason why our plant is pale green is because it is getting too much light and not enough water. The plant in Jar B is still just bloated with foggy, muddy water, but I can see almost tiny roots flowing up to the surface of the water, probably because the molecules in the soil are spreading further apart and releasing the water in the soil. Jar C- the one with 0% air in it is looking similar to Jar B. The 2 jars have practically the same amount of water, color of water, and development features. Philip: Plant A is starting to bend a lot now i think it is because of the very skinny stem so it can hold the weight of the leaves. I think that we should give jar a something to lean against but for now i just put it leaning against the wall next time i will try to get something better. jar b and c are getting more full every time we water the plants and there is still that layer of yellowish water in the middle of two layers of dirt which is getting bigger.

=
Jenny: Today Philip and I noticed that plant A is dying. Instead of sagging to the side curved, it's sagging at a sharp angle. I think it might have just been broken by someone, because it is healthy at the stem until the bend. Jars B and C are nearly filled to the brim with water, because the water just isn't being soaked up by the soil or evaporated. The merky water is a swampy-green color, at least when held up to the light. The soil in Jar A, however- is moist and cool, perfect for the plant to thrive in. I think it's strange that even though Jar B accesses air easier then Jar C, the plants in the two jars are practically at the same development. Philip and I figured that actually- it might not be too bad if the plants in Jars B and C didn't germinate, because even if they did; they'd hit the bottom of the Styrofoam cups.===== Philip: Jar A is almost dead :( because it got bent and now it is losing its color. I think it got bent because of when it had a growth spurt to try and find light it wasn't working on the stem to get it thicker and stronger so now when it has light it has a very thin stem and i broke from someone that probably just touched it. The leaves on the plant are also starting to shrivel up which i think is a sing of not getting enough water because o f the bend in the stem. But jar b and c have plenty of water (way to much) and now the water level in jar b has reached up to the styrofoam cup at the cup and the only reason why jar c is not at the styrofoam cup is because that jar is a little tiny bit bigger.
