Hypothesis and Variables Worksheet: Hypothesis And Variables Worksheet Answer Key
Hypothesis
A hypothesis is a proposed explanation for a phenomenon. It is based on evidence and observation, and it can be tested through experimentation or further observation.
Hypotheses are important in scientific research because they allow scientists to make predictions about the world around them. These predictions can then be tested, and the results can be used to support or refute the hypothesis.
Here are some examples of hypotheses:
- If I increase the temperature of a gas, then the volume of the gas will increase.
- If I give a plant more water, then it will grow taller.
- If I study for a test, then I will get a better grade.
Variables
A variable is a factor that can change in an experiment. There are two main types of variables: independent variables and dependent variables.
The independent variable is the factor that the experimenter changes. The dependent variable is the factor that is affected by the independent variable.
Here are some examples of variables:
- Independent variable: the amount of water given to a plant
- Dependent variable: the height of the plant
- Independent variable: the amount of time spent studying
- Dependent variable: the grade on the test

Answer Key
Provide an answer key for the hypothesis and variables worksheet.
Include explanations for each answer.
| Hypothesis | Independent Variable | Dependent Variable | Explanation |
|---|---|---|---|
| If I increase the temperature of a gas, then the volume of the gas will increase. | Temperature | Volume | The volume of a gas is directly proportional to its temperature. |
| If I give a plant more water, then it will grow taller. | Amount of water | Height of the plant | Water is necessary for plant growth. |
| If I study for a test, then I will get a better grade. | Amount of time spent studying | Grade on the test | Studying helps to improve test scores. |
FAQs
What is the purpose of a hypothesis?
A hypothesis is a proposed explanation for a phenomenon that can be tested through experimentation. It serves as a starting point for scientific inquiry, guiding the design of experiments and the interpretation of results.
How are variables classified?
Variables are classified into two main types: independent variables and dependent variables. Independent variables are those that are manipulated or controlled by the experimenter, while dependent variables are those that are measured or observed as a result of changes in the independent variables.
What is the importance of using an answer key for a hypothesis and variables worksheet?
An answer key provides students with a reference point for checking their understanding of the concepts covered in the worksheet. It helps them identify areas where they may need additional support and ensures that they have a clear understanding of the scientific process.
