Question

Question: What is the effect of day length on plant

growth?
Hypothesis: Plants will grow more when the day is
longer.
Describe the experiment you would use to test the
hypothesis. Be sure to include variables as well as
experimental and control groups.
the experiment to measure if days with more daylight makes
plants grow more than days with low daylight will measure
the size of the stem and weight then we will have one
experimental group under permanent artificial léd daylight
and our control group in regular daylight.
What information did you include in your
experiment?
Odependent variable
independent variable
control group
experimental group
day length
measured amount of plant growth
comparison of control and experimental
groups

Answer 1

An experiment can be conducted to test the effect of day length on plant growth. By comparing the growth of plants under different day lengths and measuring the size of the stem and weight, the hypothesis can be tested. The experimental group exposed to longer day length and the control group exposed to regular day length will help determine the effect of day length on plant growth.

Step-by-step explanation:

To test the hypothesis that plants grow more when the day is longer, an experiment can be conducted by comparing plant growth under different day lengths. The independent variable is the day length, with two levels: longer and shorter days. The dependent variable is the amount of plant growth, which can be measured by the size of the stem and weight. The experimental group will be exposed to permanent artificial LED daylight, while the control group will be exposed to regular daylight. The plant growth of both groups will be compared to determine the effect of day length on plant growth.
