Austin+and+mikaylas++Soil+types

__The Problem:__ does it make a difference if you change were the plant is growing in? __Hypothesis: (Austin) I think that the rocks will do the best because rocks have a lot of minerals that the plant will be able to use for nutrients. (Mikayla) I also think that the dirt will do the best, because the dirt absorbs the water better than the others__ __Procedure__:
 * __Plant Investigation__ **
 * 1: Get 4 cups,
 * 2: Put 1 cup of soil (or the ones we are using)
 * 3: Plant the seed3.5cm deep
 * 4: Water the plants with 20 millaletres of water every 2nd day
 * 5: Measure the heights of each plant every 2nd day, and record observations,
 * 1) 6 At the end of this project, we will measure the height of all 4 plants

__Materials: Rocks, non-filtered tap water, soil, sand, cups for the pots, 4 bean seads, syringe, a 1 cup measure. __ __Variables:__ Manipulated: The types of soil we are growing the plants in.

Responding: The __height that the plants will grow throughout the whole project and every 2 days. __

Controlled: The amount of water __they get, the amount of light they get, the brand and model of cups they are in, the temperature they are in, the room they are in.__

__Observations/Logbook:__ __Date: October 2nd 2009. Today we planted all 4 of our beans in 4 different Styrofoam cups. We also watered them for the first time.__ __Date: October 5th 2009 Today all of the plants are still 0cm and we have not seen any physical changes.__ __ Date: October 8th 2009: today all of the plants still have not grown at all except for the rocks they have grown approximately 0.5cm __ Date: october 9th 2009: we desided that our plants needed to be watered 20ml ever single day because after 2 days they were looking very dry, so today when i watered them the sand was still at 0cm and the dirt was starting to grow at a height of 0.5cm. I watered them and the rocks are still 0.5cm. __Date:October 10th 2009: today when i watered the plants the dirt plant had grown another 0.5cms so it is now at 1-cm, unfortunately the sand is still not showing any signs of growth. Today I watered all the plants and the rocks are now 1cm but the water is still 0cm.__ Date:October 11th 2009: Today when i went to water the plants i saw that the soil plant was kind of curled over but i could see the top of the plant still in the dirt so i think that it is going to grow quite a bit within the next day because the top will come out of the soil. With the sand i can still not see any signs of growth of the plant. Today I saw lots of of brown spots on the bean in the rock but it grew to 2cm. The water is still 0cm __ Date: October 12th 2009: today when i went to water the plants i could see a very small bit of the sand plant starting to show but when i put the water in it sat at the top so i poked holes in the bottom of the plants to let the water out, and the dirt plant has grown up to 2.5cm. today i noticed that in the rock plant had a little leaf like thing came out of the bean and the plant is still 2cm. the water plant is 0cm still. __ Date:October 13th 2009: today when i went to check the plant the dirt had two leaves on the top of the plant, and the sand was still curled over in the sand. Today the rocks basically stayed the same from yesterday and it is still 2cm and the water is still 0cm.

Date: October 14th 2009: Today when i watered the flowers the dirts plant had grown a whole 3cm so it is now 6.5cm i think because the leave came out, and the sand is starting to come out of the ground but still at 1.5cm. today the plant in the rock is starting to die i think this is because, at school me and cole saw the bulb ripped off the roots. so that is why i think this is why it is dying i don't think it will grow any more. The plant in the water is starting to come out of the seed pod casing.

Date:October 15th 2009: Today when i went to water the plants not much had changed they had just grown a bit, the soil plant was 8-cm tall, and the sand plant was 2.5-cm tall. today i noticed that the tip of the rock plant is starting to turn brown and it is still 3cm. the water plant still remains at 0cm.

Date:October 16th 2009: Today the plants had grown quite a bit since the last time, the soil plant has grown up to 11-cm tall, and the sand 3.5-cm. Today it looks like the rock plant has not grown and is still at 3cm. the water plant is still 0cm an the bean is still at the bottom of the cup.

Date:October 17th 2009: Today i saw the rock plant had stayed the same is still 3cm and the water plant i still 0cm and is at the bottom of the cup i don't think the rock is going to grow anymore because the bulb has been ripped off by somebody.

Date:october 18th 2009: today when i watered the plants the leafs on the soil plant had gotten very large, in fact i think almost half of the plants size is just from the leaves (13-cm), and the sand plant is just starting to get its leaves, but the bean is making some of its height (5-cm)

Date: October 19th 2009: today we are going to re-plant the rock plant because unfortunately some one tore the top off of the plant so we have to re-plant. but the other plants are growing very well except for the water which is still floating on the top of the water.

Date:October 27th 2009: today all of the plants that were growing are still the only ones that are growing, the soil is 16-cm, and the sand is 12-cm. the leaves on the sand are very small and round, and the leaves on the sand are very big, almost bigger then the stem. Date: October 26th 2009 Today the water looks like like an explosion happend inside the bean and all the white stuff inside the bean is all spread around in the bean. The dirt is only a bit bigger then the sand but the Leaves of the dirt plant are 9cm and the plant in sand is 13cm and the leaves are 1cm. since we replanted them only short ago it is still 0cm.

date: November 2nd 2009:today when we watered our plants we noticed that the rock plant had a very skiny stem and it was so skinny it broke. the other plants are doing good except for the water one which inside of the cup it looks like it broke open, and the soil one is doing the best.

Date:November 5th 2009: Today when we watered the plant we noticed that the soil plants leaves got even bigger, and now just the leaves are 9.5-cm big, none of the plants seem to be dying because the colour is a natural alive green colour, on the soil and sand plants. the other plants are still not growing the sand plant is very small and the leaves are still 1 cm big. the water is getting very mushed up and the water is very brown. I think that the soil plant is a lot more healthy then the sand plant because it is a lot more green and has way greener and bigger leaves. the stem of the soil plant is a lot thicker and greener then the sand plant.

Date: November 13th 2009: today the soil plants area bit bigger and it looks like every time we check it it grows about 1cm. today it looks like the sand plant has died. i think it is dead because it has wilted and half of it is slouched over and it shrunk today. the water plant still looks like it blew up and the water now is very murky. the rock plants have not grown since we replanted. the soil plants look very healthy compared to the sand plant it very green and the leaves are very big. the sand plant is now kind of yellow it looks like it is dead now that the leaves are crunchy and when it was alive the leaves were tiny and were very brown.

Date: November 16th 2009: today the soil plant grew to 20cm. It is still very green and thick at the stem it has 6 leaves the firsts leaves are very big they are almost half the size of the plant. the sand plant is dead i know this because the top half of the plant has actually fallen off. It is very yellow and brown. the rocks have still no germinated the seed still looks like it blew up and know it will not grow anymore because there is almost no seed left it just looks like it is a brown piece of paper in a cup.

Mikayla's Conclusion: In conclusion my hypothesis was right because the sand and the dirt plant grew the most but unfortunately we did not water out sand plant one day and it died, and the rock plant has still not grown since we replanted it. when we were doing our experiments i think what we could have done better is change the amounts of water we gave each plant because we gave them all the same amount of water each day, when i think that somedays some of the plants did not need that much water. me and austin did make some other mistakes as well, on some of the days we waited almost 6 days to water some of the plants which may be why some of the plants (sand plant) died. I think that the water plant did not grow at all and just turned in to mush in the cut, was because there was WAY to much water for it and it could not absorb it, so it kinda exploded. I am not sure what i can say for the rocks because someone broke it the first time and after we replanted them they have not yet re-grown. I think that what happened to that sand plant was because the sand can absorb and keep water for a wile, so the seed has time to absorb it out of the sand, but because the sand absorbs so much, you must continue to water it constantly because i think that the sand took half of the water from the seed. I think that the soil plant did the best because it holds and keeps was but it will keep for a longer time then the sand so the seed has a lot of time to absorb the water, and unlike the sand it will give it that water, wile the sand will just absorb and keep the water. In this experiment i think that this proves that most people put there plants in dirt for a few reasons, 1. it is very easy to get, and 2 from what we found out in our experiment it is also the best for keeping and giving away all the water to the plant, but it knows when the seed does not need any more, so it keeps it for itself. I think that i could use this in real life, when i plant my garden so that i know not to plant any of my plants in the soils that will not help it grow very well.
