6. Identify another question that you could ask and then explore after
completing this experiment.
Hide Hint
Hint: These questions should build off the initial experiment exploring the effects of
caffeine on Daphnia's heart rate.
Select all that apply:
What is the optimal concentration
range of caffeine for inducing
changes in Daphnia's heart rate?
Do different light intensities affect
the heart rate of Daphnia?
Does temperature influence the
interaction between caffeine and
Daphnia's heart rate?
How do other chemicals, such as
nicotine or ethanol, affect
Daphnia's heart rate in comparison
to caffeine?
Do Daphnia like caffeine in the
environment?
Does the heart rate of Daphnia
change with different water
temperatures?
