Hi
I just did a required practical on measuring the rate of reaction by a continuous monitoring method. We measured the volume of Hydrogen gas produced with a gas syringe, when magnesium strip reacted with HCl.

I don’t know what variable I was unable to control. Temperature maybe? But could I control that? And how can I have modified experiment to see if it had an effect?
Any help is appreciated.

you can control temperature with a water bath
You could modify the experiment by having a negative control i.e. one experiment with the temperature controlled vs another without
I don't know if it's the right answer but just a guess ^

Assuming it's a very simple syringe experiment, you were likely unable to control the temperature.

Temperature would have been taken as "room temperature" which is going to be different depending on said room.

You could repeat the experiment by heating the syringe or whatever reaction chamber you used in order to detect the effect of heating the system.

I hope this is clear
