and conclusions. Scientists recognize that experimental findings may be imprecise due to variables difficult to control, such as changes in room temperature, slight miscalibrations in lab instruments, or a types of experimental errors flawed research design. However, scientists and college professors have little tolerance for human errors occurring due to carelessness or sloppy technique. If you know you really messed up, redo the experiment. Failure to Follow Directions Before leaping into a laboratory activity, carefully read the instructions in the lab manual thinking about the purpose of the experiment and possible results. If experimental error examples physics you don’t understand a step, consult with your lab partner or instructor before proceeding. Perform each step of the experiment in the correct order to the best of your ability. Don’t attempt shortcuts in the procedure to save time. Conducting an experiment is similar to following a recipe in the kitchen but far more exacting. Even slight deviations can change your results in dramatic ways. Mishaps in Measuring Spilling chemicals when measuring, using the wrong amount of solution, or forgetting to add a chemical compound are mistakes commonly made by students in introductory science labs. Measurement errors can result in flawed data, faulty conclusions and a low grade on your lab report. Worse still, you may cause a dangerous chemical reaction. Ask your lab instructor for guidance if you know your measurements are way off from the instructions; sometimes the experiment or your calculations can be adjusted to avoid starting over. It is better to be safe than to risk injury to yourself and others. Contamination Failing to maintain sterile conditions can cause contamination and produce

This includes experiments conducted by famous scientists also. Research Questions: Is it possible to perform each calculation of data precisely to get an exact answer? If you need 50g of water, is it possible to pour 50g of water all the time? Explain. If you round an answer during a calculation, does it change your answer considerably? Why or why not? Materials: Graduated Cylinder Pipette with a safety bulb Beaker Water Electronic Balance Experimental Procedure Weigh the graduated cylinder with the electronic balance and record the weight on the table. Put 100g of water in the graduated cylinder and then weigh the cylinder with care so that the water does not spill. Calculate the difference between the weight with the water and the weight without the water. Repeat steps 1-3 again 2 more times. Repeat steps 1-4 with your pipette (10g) and beaker (100g) and

This is usually used to differentiate the source of errors from other causes such as measurement error, random variation, machine failure, lack of calibration, improper design, etc. I believe it was Einstein who said that it is difficult to make things fool proof because fools are so damn ingenious. Machines and automated system are very good at doing the same thing over and over again (good repeatability and reproducibility). Humans get easily bored doing repetitive tasks so frequently, machines and automated systems are used to control repetitive processes. Human nature is such that, when people are given control over a process, they are likely to experiment with the process, turning knobs and adjusting things to see what happens. Sometimes this leads to significant improvements in a process but it often leads to increasing the variation in processes. For example, the airline industry and the military have done a great deal of study on human factors in aircraft accidents and near misses because, with today's technology, planes are capable of taking off, flying across the country, and landing without any input from pilots. Lack of training, inattention to detail, and poor decisio
