What will be the independent and dependent variable....?

for Venus?
I am doing a project in school to make a probe for Venus. I need to identify the independent and dependent variables. Please help!!
For example, what must be kept the same and what will be changed.
Answer quickly because it has to be in by tomorrow and I'm seriously stuck!!

What are you trying to look for

You need to be more specific. What are you measuring? What variables can you keep constant? Here is a site where you can find answers after you identify the variables in your project.

When designing a project to make a probe for Venus, the independent variable is the one that you can deliberately change or manipulate, while the dependent variable is the one that you want to measure or observe as a result of those changes.

In the context of a probe for Venus, some possible variables to consider could be:
1. Independent variable: Materials used for the probe's construction, such as metals, polymers, or ceramics.
2. Dependent variable: The probe's ability to withstand the extreme heat and pressure on Venus' surface.

To conduct a meaningful experiment, it is important to keep certain variables constant (also known as controlled variables). These are the factors that should remain the same throughout your experiment to ensure that any observed changes in the dependent variable can be solely attributed to the changes in the independent variable.

For a probe project for Venus, some potentially important controlled variables could include:
1. Temperature: Keep the temperature constant during testing to eliminate its influence on the probe's performance.
2. Atmospheric pressure: Ensure that the atmospheric pressure remains the same for each test to isolate the causes of any observed changes.
3. Surface conditions: Maintain a consistent surface environment to eliminate variations in terrain or other factors that might affect the probe's behavior.

By considering these variables and their roles in your project, you can better identify the independent and dependent variables and conduct a controlled experiment to develop an effective probe for Venus.
