Fertilizer+vs.+No+Fertilizer

 The Problem: How do plants respond to fertilizer in the water versus just regular water? Haley's Hypothesis: I think that the one with the fertilizer will grow taller because it has added nutrients. Nutrients are really good for a plant and they tend to help growth. Quentin Hypothesis: I think that the fertilized seeds will grow bigger then the two in the soil because if fertilizer doesn't work then why would people buy it.
 * Plant Investigation ** 

Procedure:  1. Put the same amount of soil in each pot. 2. Plant 2 seeds in each pot 2 cm deep. 3. Give each plant 2 tablespoons. In the two plants labelled fertilizer, add 1 drop of fertilizer to the water and stir in. We are giving the plants water every 4 days when we where giving them water every 2 days made them yellow. 4. Leave to settle 5. Come back every fourth day and repeat step 3  Materials: 

· 8 Seeds · A Container of Fertilizer · 4 Pots (We can bring them in need be · Soil · Water -Rubber gloves or garden gloves   Variables:  a. Manipulated: 2 of the 4 pots will have fertilizer

b. Responding: Some of the plants will grow taller and bigger than the others

c. Controlled: The amount of water is staying the same, the amount of soil, the size of each pot, the location is the same, and the lighting is the same.

Observations/Logbook: 

Day 1: Date: October 2: (Quentin) We planted them today. We're giving them 2 table spoons and 1 teaspoon of water.

Day 3: Date: October 5: (Haley) So far, there is no growth shown in any of the plants. No germination is showing. This is 2 days after planting.

Day 6: Date: October 8: (Haley) There is no growth or any sign of germination. This is after 6 days of planting.

Day 7: Date: October 10: (Haley) All the plants are showing signs of growth and germination! Plant 1 has grown 1cm. Plant 1 is a fertilizer plant. Plant 2 has grown 1.3cm. Plant 2 is also a fertilizer plant. Plant 3 has grown 2.3 cm! Plant 3 is a non-fertilizer plant. Plant 4 has grown 0.6cm. Plant 4 is a non-fertilizer plant. So far, the fertilizer plants have grown 2.3cm together and the non-fertilizer plants have grown 2.9cm together. It's a very close race!

Day 9: Date: October 12: (Haley) Plant 1 is 2.2 cm tall right now. It is turning yellow and it looks really over-watered. I think we should water every 4 days because if we water every 2 days, it'll kill them. I think we should change it to every 4 days. I didn't water today because all of them looked pretty over watered. On the procedure I'll change it to every 4 days. Also, I put each plant on a tray and I poked 2 holes in the bottom of each plant, each in the exact same location and exactly the same size. Plant 2 is 8.5 cm tall! It's the largest of all the 4. It's also opening up. Plant 3 is 7.5 cm tall! It's opening up just slightly. Plant 4 is 2.5cm tall.They're all slightly yellowed. Together, they fertilizer plants have grown 10.7 cm together and the non-fertilizer plants have grown 10 cm. It's still very very close!

Day 13: Date: October 16: (Haley) Plant 1 is 10 cm tall. The yellowing is gone which is good. Now it's just opening up and crinkled which makes it look sort of wilted. Plant 2 is 24 cm tall and it looks very healthy. Plant 3 is 28 cm. It is the tallest and healthiest looking of all 4 of the plants. Plant 4 is 14 cm and it looks sort of diseased. It has specks on the leaves. To me, it looks like the carbon dioxide levels in the plant are not high enough. I think this because when something like this happens, one of the needs isn't being met, and carbon dioxide is the one that enters through the leaves. It could also be sunlight but to me, it doesn't look like an issue that would occur due to lack on sunlight. All of the plants are very green, which is good. It means the chlorophyl levels are right which means that photosynthesis is occurring! Plant 4 is the exception because the leaf is starting to change colour. The fertilized plants have grown 34 cm together. The non-fertilized plants have grown 42 cm together. The non-fertilized plants are pulling ahead a bit.

Day 16: October 19: (Quentin) The biggest soil plant (number 3) is 29 cm. The fertilizer plant (number 1) is 17 cm long. The other fertilized plant (number 2) is 25 cm long. The last soil plant (number 4) is 17 cm long. Both number 1 and number 4 have holes in the leaves it could be because there the same length and the germination stage does that when there that long but i don't think thats the reason all of the plants are green and have 2 leaves. This is day 16 after we planted them.

Haley: Plant 1 is 16 cm tall. It is the shortest plant. It is starting to look healthy again! Plant 2 is 25.5 cm tall. It's looking very healthy and it's got a distinctive green colour. Plant 3 is 31 cm tall! It is the tallest plant and it's the deepest green. Plant 4 is 18 cm and it's still diseased looking. The speckles on it are starting to disappear but it's still pretty unhealthy. I wonder if the air change at school helped it. The fertilizer plants have grown 41 cm. The non-fertilizer plants have grown 49 cm. The non- fertilized plants are doing a noticeable amount better than the fertilized.

Day 24: October 27: (Haley) Plant 1 is 20.5 cm. The leaves are starting to get holes in them. Plant 2 is 28 cm tall. The leaves edges are starting to wilt. Plant 3 is 31 cm tall. It's green and it looks really healthy. It's the tallest, healthiest plant out of all of them. Plant 4 is 17 cm tall. It's looking really unhealthy. The leaves are full of holes and it's slightly discolored.

Day 30: November 2: (Haley) So far, plant 1 is 21 cm in height. It is looking very unhealthy and like it's going to drop any second now. I think it's because lack of sunlight. Plant 2 has officially died and I don't think it's going to be able to revived. Plant 3 is still the healthiest and it's looking very good. It's 31 cm tall, it hasn't grown for about a week now. Plant 4 has died and it has only the slightest chance of being revived. I don't think that it'll ever get back in it's health.

Day 33: November 5: (Haley) Plant 1 is dead. Which is to bad because it was the last fertilizer plant still alive. Plant 2 is still dead, as was expected. Plant 3 is 31 cm tall. It hasn't grown any taller, but it has 3 new leaves and some more are growing on it! It has 5 leaves in total right now, and it has 3 new little buds just growing. Plant 4 is still dead, which is also expected. I think that most of the plants are dead because it's not getting much fresh air, it isn't getting any sunlight, and they're getting overwatered at times. Also, the carbon dioxide levels in the classroom might be having a bit of an affect on it.

day 41: November 13: (Quentin) all plants are dead plant number 3 died it was the last plant that was alive it might survive if it still has roots but some how it broke now all the plants are dead the last time I checked how long it was it was 34 cm. Someone might have pulled the plant out or it ripped by it self because it started to lean over for the last few days.

Haley: Unfortunately, all of the plants are dead or very close to death. I think this is because the plants weren't getting the proper necessities they need in the class.
