Mean are very important in the development of lab technique for students of cell biology. This experiment will help laboratory students gain experience in using the spectrophotometer. This instrument takes advantage of the regular light absorption and scattering patterns of chemical structures (Lab Manual, p.19).
if you dont cover your solution with the cap on the colorimeter,your results will be way off as your solution is exposed to muchmore light than it should be exposed to.

What are some sources of error when obtaining a boiling point?
The primary source of error in taking a temperature reading is the thermometer, itself, and reading it properly. Standard, school-use thermometers are not precision instruments, and even very precise ones need to be calibrated occasionally. Even if your thermometer is accurate to within one percent of the reading, a measurement of 100 degrees has an uncertainty of plus or minus one degree, meaning that the actual temperature may be anywhere between 99 and 101 degrees… Read More

That depends on how long the moving clock keeps moving before you take it into the lab and measure its error, and it also depends on how small an error you can measure. A clock flown around the world on an airplane arrives with measurable error that corresponds to the error expected due to relativistic time dilation. Also, corrections are routinely included in decoding the signals from GPS satellites to account for the relativistic error… Read More

Can percent error be negative?
Sometimes you will take the absolute value of the percent error because your estimated number could be less than the theoretical, meaning the calculation is negative. But an absolute value is always positive. A percent error can be left as a negative though, and this would be perfectly acceptable (or even preferred) depending on what you're doing. Answer: In the sciences, a negative percent error indicates a low result. If you have a 0% error… Read More
A source of error is any factor that may affect the outcome ofan experiment. There are countless conceivable sources of error inany experiment; you want to focus on the factors that matter most.Identify each source of error specifically and then explain howthat source of error would have affected the results. Keep in mindthat an 'error' to a scientist does not mean 'mistake'; it moreclosely means 'uncertainty'.
Many students are tempted to say 'human error', but this term isvague and lazy; any decent teacher will not accept it. Instead,think about specific things that happened during the lab exercisewhere the end results may have been affected.
To give an example one might find in a bio lab: perhaps a waterbath's temperature was not monitored very carefully and you foundthat an enzyme's activity was greater than you expected. In thatcase, you could write something like,
'The temperature of the water bath during this exercise wasnot monitored carefully. It is possible that it was warmer orcooler than intended, and this would have affected the enzymeactivity accordingly. The fact that our enzyme activity was foundto be higher than expected leads me to believe that perhaps thewater bath was too warm.'
