In order to make the best assumptions of the results the reader of the amount of heart beats there are and the concentration of the solution should be uninformed.
11.Repeat the procedure using other water fleas from the culture solution and fresh, clean slides and cover slips. Replace the water with caffeine solution. Repeat the procedure using several different concentrations of caffeine.
