Students design an experiment to find out how changing the volume of water in a cup affects the force needed to drag it across a rough surface. The diagram shows the students' experiment.

Information
Short description, A diagram.,Long description,
The diagram shows a cup filled with water resting on a flat surface. Attached to the cup is a spring scale. As the scale is pulled to the right, it pulls the cup to the right as well.
Question
Drag the variable(s) and constant(s) to the appropriate places in the table.
Response area with 3 blank spaces
Independent Variable(s) Dependent Variable(s) Constant(s)
Blank space 4 empty
Blank space 5 empty
Blank space 6 empty

To identify the variables and constants in the experiment described, we can categorize them as follows:

  1. Independent Variable(s): This is the variable that the students change in the experiment. In this case, it is the volume of water in the cup.

  2. Dependent Variable(s): This is the variable that is measured or observed in response to the changes made in the independent variable. In this experiment, it is the force needed to drag the cup across the rough surface, which can be measured using the spring scale.

  3. Constant(s): These are the variables that remain unchanged throughout the experiment to ensure a fair test. This could include factors such as:

    • The type of rough surface used
    • The material of the cup
    • The environment (temperature, atmospheric pressure, etc.)
    • The distance over which the cup is dragged

Based on this information, the placement of variables and constants in the table will be:

Independent Variable(s): Volume of water in the cup
Dependent Variable(s): Force needed to drag the cup
Constant(s): Rough surface type, material of the cup, environmental conditions

You can place these in the given table as follows:

| Independent Variable(s) | Dependent Variable(s) | Constant(s) | |---------------------------------------|-----------------------------------------|---------------------------------------| | Volume of water in the cup | Force needed to drag the cup | Type of rough surface | | | | Material of the cup | | | | Environmental conditions |

(Note: The specific details can vary based on full context, but this layout should generally fit the provided information.)
