Light+Amounts

Type in the content of your page here. __Light Amounts

The Problem:__ Will the amount of sunlight that a plant gets affect its growth? __Hypothesis: __I think that the plant in sunlight will grow the most and the one in the dark will grow the least, because plants need sunlight to grow. __Materials: __ - 6 Pots (Plastic Cups) - Seeds (6 or so) - Soil - Measuring cup - Water - Ruler - Fertilizer __Variables:__ a. Manipulated: The amount of sunlight that each 2 plant get.

b. Responding: The amount of cm the plant grows in height.

c.  Controlled: Our Controlled Variables are the amount of Water, Air, Space, Nutrients and Soil that we use for each 2 plants.

__Procedure:__ 1. Add the same amount of soil to each cup (about ¾ of the cup) 2. Put 1 seed into each cup, 2 cm deep. 3. Put 2 cups in the light, 2 in the dark, and 2 in middle light (Keep them where they are though the entire experiment) 4. Give each plant 5 tablespoons of water everyday. 5. Every week, add 1 tablespoon of fertilizer to each plant.

__Observations/Logbook:__ __Day 1: Monday September 28th 2009__ There Seems to be no germination at all.

__Day 2: Thursday October 1, 2009__ Plant C has grown 4.5cm tall, it has 2 small leaves. Plant E has grown 7cm and F has grown 12cm.Both of them have a sprout already. I’m very surprised with the plant growth it seems as thought the plants in the Dark have grown the most so far.

__Day 3: Friday October 2nd, 2009__ There seems to been no growth at all since Day 2.

__Day 4: Monday October 5th, 2009__ Plant A seems to have grown over the weekend it has grown 7.5cm, it is starting to sprout a leaves. Plant C is the exact same as it was the 2nd day. E and F have surprised me even more this time, they are both growing the most even though they're in the dark. E has grown to be 25cm and F has grown to be 24cm. E has grown 18cm over the weekend and F has grown 12cm.

__Day 5: Tuesday October 6th, 2009__ Plant A is now 12cm, which is an 4.5cm increase in height. It has sprout and it is dark green. I don't know what's happening with plant D because it never seems to grow, but are least it has a pod now, it is bright green as well. Plant E and F are the same as they were yesterday, they have a very sickly yellow and green colour, i don't think they are very heathy.

__Day 6: Wednesday October 7th, 2009__ Plant A has grown to be 16cm, which is a 4cm increase from yesterday. The rest haven't ether haven't geminated or haven't grown since yesterday

__Day 7: Wednesday October 14th, 2009__ Plant A is Wilting, i think it that's because when i was walking home from the bus stop they froze, but even though it's wilting it has grown to be 18cm which is an 2cm increase. Plant C is wilting as well and the stem snapped it has grown to be 19cm, which is an 14.5cm increase. I guess it grow a lot while i was in Radium. E and F aren't growing at all i think they're pretty much dead, they're all pale white and the top of the stems shriveled up. I'm going to start a second trial when we get back to school because i don't want the plants to die again when i walk to the bus in the morning. I'll keep on recording the growth just incase they grow these days.
