Question #6
A student had always heard the energy
drinks were absolutely horrible for the
human body, but especially for growing
kids. They decided to set up an
experiment and have a test group of
students drink an energy drink and then
they monitored those student's heart
rates to see what happened for the next
two hours after they drank their energy
drink. They had a control group that just
drank water and they monitored their
heart rate for the next two hours.
What are the
independent and
dependent variables?
