The amount of water given to the swamp plants.
The type of soil used in the swamp.
The amount of sunlight the swamp plants receive.
The height of the swamp plants.
What is the dependent variable in the experiment where the effect of sunlight on Shrek's swamp plants is tested?
The amount of water given to the swamp plants.
The type of soil used in the swamp.
The amount of sunlight the swamp plants receive.

Plants that receive 4 hours of sunlight.
Plants that receive 8 hours of sunlight.
Plants that receive 12 hours of sunlight.
In Shrek's swamp, to test the effect of sunlight on the growth of magical plants, what would be the experimental group?
Plants that receive no sunlight.
Plants that receive 4, 8, and 12 hours of sunlight.
Plants that receive only water.
Plants that are kept in the dark.
What are constants in the experiment to test the effect of sunlight on Shrek's swamp plants?
The amount of sunlight each plant receives.
The type of plant, the amount of water, and the type of soil used.
The height of the plants.
The growth rate of the plants.
Why is it important for Shrek to have a control group in his swamp experiment?
To ensure that the experiment is conducted in a controlled environment.
To compare the results of the experimental group with a baseline.
To increase the number of variables in the experiment.
To ensure that all plants receive the same amount of sunlight.
Which of the following is an example of a hypothesis in Shrek's swamp?
The plant in the control group will not grow in Shrek's swamp.
If plants in Shrek's swamp are given more sunlight, then they will grow taller.
The type of soil in Shrek's swamp affects plant growth.
Plants in Shrek's swamp need water to survive.
In Shrek's swamp experiment, why is it important to keep constants the same for all groups?

Why is it important for Shrek to repeat his swamp maintenance tasks multiple times?
To ensure the results are consistent and reliable.
To increase the complexity of the tasks.
To test different hypotheses simultaneously.
To make the tasks more interesting.
If Shrek's swamp receives more water, the number of leaves on the trees will increase.
