Should you follow a protocol when experimenting?
Risk assessment and safety is important to be followed as the instruction in order to have a safe workplace.
Following the protocol is one another skills which I developed during the experiment. By following all the procedure step by step. Our result will be more accurate. The grinding process must be done carefully by not adding too much sand or alcohol. All the line in chromatography paper must be done by pencil. The chromatography paper must be placed horizontally into the beaker. The solvent must not touch the origin line otherwise it will ruin all the pigment.
Keeping accurate records is another skill which I can apply for any experiment which I suppose to do in the future. The record must be clear to read as someone else can use it. It is also good to have your records in order to compare your results with your classmates. Make sure that all the results are written in a table and with the units.
Making precise measuring is another important skill. We can increase our precision by paying attention while measuring and using accurate equipment for measurement, also by increasing the sample size.
Using accurate equipment as a very important skill. In the chromatography experiment, I used the capillary tube for applying the mixture into the chromatography paper which is more accurate than using a stick or maybe a pipette.
