Differentiating Independent and Dependent Variables

This video tutorial from Moomoomath and Science explains the difference between independent and dependent variables in a science experiment. It introduces constant variables and focuses on how independent variables are manipulated while dependent variables are measured. The video provides examples, such as the effect of car color on temperature and the impact of water on tree height, to illustrate these concepts. It also explains how to graph these variables using the DRY MIX method, where the dependent variable is on the Y-axis and the independent variable is on the X-axis.

What type of variable remains unchanged throughout the experiment?

• Constant variable

• Manipulated variable

• Dependent variable

• Independent variable

What is another name for the independent variable?

• Responding variable

• Measured variable

• Manipulated variable

• Control variable

In the car color experiment, what is the independent variable?

• Temperature inside the car

• Car model

• Duration of parking

• Color of the car

Which variable is manipulated by the experimenter?

• None of the above

• Constant variable

• Independent variable

• Dependent variable

What does the dependent variable depend on?

• The hypothesis

• The experimental setup

• The manipulated variable

• The constant variable

In the tree height example, what is measured as the dependent variable?

• Sunlight exposure

• Tree height

• Soil type

• Amount of water

What is the role of the dependent variable in an experiment?

• It is hypothesized

• It remains constant

• It is measured

• It is manipulated

What is the independent variable in the banana and blood pressure study?

• Type of banana

• Number of bananas eaten

• Blood pressure

• Gender of patients

Which variable is graphed on the y-axis?

• None of the above

• Constant variable

• Independent variable

• Dependent variable

What does 'DRY MIX' help you remember?

• Scientific methods

• Graphing variables

• Types of experiments
