Depend variable is the one you measure, and indepent is the one that you change.
I havent done that experiment yet as i am only year 10 & gcse standard.

But i would say dep = heart rate
indep= caffine concentration

DONT COPY THIS BECAUSE I MIGHT BE WRONG. SEE WHAT YOU HAVE MEASURED AND CHANGED TO GET EACH SET OF RESULTS!!!!

Hope i helped :smile:
