However, there are ways you can change the language of the instructions to write your method section.īelow is an example of how these lab instructions were summarised into a method in a laboratory report: The method section of your report should instead be written in the past tense as a cohesive paragraph. These are not appropriate phrases to include in the lab report.Īlso note that the language of the instructions is in the present tense in bullet points. 'remember to take the reading from the centre of the meniscus…'.This is different from a lab report where you are reporting on what you did. Phrases are used here to specifically instruct the student who may be performing the technique for the first time. Experimental set-up for titration (taken from Carroll 2017) (Your teacher will provide additional guidance on the specific technique).įigure 2. Titrate the standardised NaOH(aq) into the flask with constant swirling until there is an observable colour change.Place the conical flask onto the white paper and add five drop of universal indicator to the flask.This is to make it easier to observe the colour change during the reaction. Place a sheet of white paper under the burette.Remember to take the reading from the centre of the meniscus, and from eye level. Fill the burette to the 0.0ml marking with standardised NaOH(aq).Rinse a burette with standardised NaOH(aq) and clamp it to the retort stand as shown Figure 2.Use a clean pipette to measure 25ml of HCl(aq) into a 100ml conical flask.Any experimental difficulties encountered and how they were resolved or worked around.īelow is an example of the instructions provided to a student to carry out a first year chemistry experiment.experimental set-up), usually including a diagram.
How the apparatus and equipment were set up (e.g.A typical set of instructions usually includes: These instructions are NOT written in the style of a laboratory report. You will generally be provided with a set of instructions to complete your practical work. Turn lab instructions into a lab report methodĪ common mistake students make is copying the instructions their teachers provide directly into their method section. A great way to keep track of this is to use a lab notebook during the practical work to note any change you make. You must also include any unplanned changes to the original process which occurred during the execution of the experiment. You need to describe the actions you took in a way that someone from your field has enough information to replicate the process and achieve a similar result. The method section is where you describe what you actually did during the practical work.
