Sure! Here’s how I would answer those questions:
-
What is the independent variable in this experiment? The independent variable is the depth (measured in kilometers, km). This is what we change in the experiment to see how it affects the other factor.
-
What is the dependent variable in this experiment? The dependent variable is the magnetic field strength (measured in microteslas, μT). This is what we measure and observe in response to changes in depth.
-
Based on the data, what is the relationship between the strength of the magnetic field and depth within the Earth? Based on the data, it looks like there’s an inverse relationship between depth and the strength of the magnetic field. As the depth increases (like going from 0 km to 500 km), the magnetic field strength decreases (like from 40 μT down to 20 μT). So, the deeper you go into the Earth, the weaker the magnetic field seems to be.
