Read each question carefully and provide your best answer. This worksheet will test your understanding of experimental design principles.
1. What is the purpose of a control group in an experiment?
To show what happens when the independent variable is changed.
To provide a baseline for comparison.
To collect qualitative data.
To introduce bias into the experiment.
2. Which of the following is an example of an independent variable?
The height of a plant.
The amount of water given to a plant.
The number of leaves on a plant.
The color of a plant's flowers.
3. A scientific guess or prediction about the outcome of an experiment is called a .
4. The factor that is measured or observed in an experiment is the variable.
5. It is important to change multiple variables at once in an experiment to see what has the biggest effect.
True
False
6. Quantitative data involves descriptions, while qualitative data involves numbers and measurements.
True
False
7. Design a simple experiment to determine if the amount of sunlight affects the growth of a bean plant. Identify your independent variable, dependent variable, and at least two controlled variables.
8. Observe the image above. If this experiment is testing the effect of different liquids on plant growth, what would be a good independent variable and dependent variable?
