I am doing a science fair project testing the effects of green tea and beta- blockers on the heart rate of daphnia magna... but i have some procedural questions that i haven't been able to find answers to. If anyone could help that would be great! Some specific questions are: 1. should i keep the daphnia in one large tank and then put them in separate containers before testing or just always keep them in separate containers? 2. how often do i need to test the dapnia in order for it to be considered significant? i was thinking everday for 2 weeks and then looking under the microscope 2 times 3. Oh and do i need to change the water? some websites say yes and others no so i'm really confused on that one If anyone has any tips or anything i would greatly appreciate it... i have looked through so many articles for information and asked my science teachers but still can't get any answers! Thanks again Elizabeth
