Lab #3: More volume measurements

As a follow-up experiment of Lab #1, design an experiment to answer a question that came up. Examples include repeating an experiment to check reproducibility, trying different volumes, measuring the density of water to be able to check for accuracy (you checked for reproducibility in the original experiment), and testing the influence of temperature or viscosity on the reproducibility/accuracy of volume measurements.

You should make sure that your experimental design addresses the question you are asking, and that you are making good use of your allotted time in the lab (the number of measurements should be comparable to that of lab #1 if you are planning to work with the balance and/or pipettes). If you plan a lab that requires anything in addition to what was available for lab #1, make sure you discuss this with your instructor and obtain permission.

Typically, I set aside one hour of class time to brainstorm, plan and revise experimental plans one week before the lab is done.
