Question

4 point question
create and describe your own experimental design based on the question below.
question
do lemon trees grow more lemons if you increase the amount of water they receive? (note: you are currently watering your lemon tree once a week.)
part 1: describe the steps of your experimental design below:
part 2: answer these questions based on the experiment you designed.
a. what is your independent variable?
b. what is your dependent variable?
c. state 2 constants in your design.
d. what are your experimental groups? (at least 2)
e. what is your control group?

Explanation:

Step1: Experimental Design Steps

1. Select a sufficient number of similar - sized and healthy lemon trees.
2. Divide the lemon trees into groups: a control group and experimental groups.
3. The control group continues to be watered once a week with the current amount of water.
4. The experimental groups are watered more frequently or with more volume of water than the control group (e.g., one experimental group is watered twice a week, another is watered with double the volume each time).
5. Keep other factors such as sunlight exposure, soil type, and fertilizer application the same for all groups.
6. Monitor and record the number of lemons produced by each tree in each group over a specific period (e.g., a growing season).

Step2: Answering Questions

A. Independent variable

The amount or frequency of water given to the lemon trees.

B. Dependent variable

The number of lemons produced by the lemon trees.

C. Constants

1. Soil type (keep the same type of soil for all trees).
2. Sunlight exposure (place trees in areas with similar sunlight conditions).

D. Experimental groups

1. Group 1: Watered twice a week.
2. Group 2: Watered with double the volume each week compared to the control.

E. Control group

Lemon trees watered once a week with the current amount of water.

Answer:

A. The amount or frequency of water given to the lemon trees.
B. The number of lemons produced by the lemon trees.
C. Soil type, Sunlight exposure.
D. Group 1: Watered twice a week; Group 2: Watered with double the volume each week compared to the control.
E. Lemon trees watered once a week with the current amount of water.
