In this experiment, the blank
was intentionally manipulated. This was the independent variable.
The dependent variable measured was the blank

Here we need to identify the independent and dependent variables in an experiment.

Sadly, we have no information about the experiment, so we need to give a general answer.

In an experiment, we can define 3 types of variables.

Now that you know this you could guess which one is the independent and which one is the dependent.

Just to give an example, suppose that your experiment is "How hot a piece of steel gets in an oven as a function of the time it is inside".

The time, the thing that you control, is the independent variable.

The temperature of the piece of steel, the thing you measure, is the dependent variable.

The controlled variables are things like the type of oven, the temperature at which the oven is, the position of the piece of steel inside the oven, etc.

If you did the walking beans activity on edge,

The answers are "color of light in the environment" and "number of beans eaten"

hope this helps :)
