Can someone me with this?

connor & miguel want to investigate if the type of fertilizer changes the color of their hydrangea flowers. they select 10 hydrangea bushes & plant them in the same yard with the same type of soil. every bush gets 3 cups of fertilizer, but each receiving a different brand. one bush gets no fertilizer. all bushes receive morning sunlight and no afternoon sunlight. all bushes are watered the same amount every other morning. after 4 weeks, the boys observe the color of the blooms on each bush.

1. independent variable:

2. dependent variable:

3. hypothesis:

4. control group:

5. experimental group:

6. constants:

Independent variable: FERTILIZER.
 This is the variable that you think affect your dependent variable and so you change it and use different types of it to confirm your prediction.
Dependent variable: COLOR.
That is the variable you are interested in.
Hypothesis: THE TYPE OF FERTILIZER USED IN CULTIVATING HYDRANGEA FLOWER AFFECT THEIR COLOR.
 An hypothesis is a generalized statement which predicts the relationship between the variables you are examining. 
Control group: THE GROUP THAT DID NOT GET ANY FERTILIZER
The control group is the group that does not receive any treatment. 
Experimental groups: THE GROUPS THAT RECEIVED FERTILIZERS.
The experimental group is the group that receives treatment. 
Constants: TYPES OF SOIL USED, MORNING SUNLIGHT, WATER AND THE NO OF DAY THE EXPERIMENT LAST.
The constants are the inputs into your experiment which you give to all the groups.

1. Independent variable: type of fertilizer

2. Dependent variable: color of hydrangea flowers

3. Hypothesis:  The type of fertilizer changes the color of their hydrangea flowers.

4. Control group: One bush gets no fertilizer.

This bush is their basis of comparison on what changes the type of fertilizer have on different bushes.

5. Experimental group: 9 bushes where every bush gets 3 cups of fertilizer, but each receiving a different brand.

Since there are 10 hydrangea bushes and 1 of these is the control group, the rest are experimental groups.

6. Constants: - Variables that are the same all throughout the experiment.

* Planted in the same yard with the same type of soil.

* All bushes receive morning sunlight and no afternoon sunlight

* All bushes are watered the same amount every other morning.
