How to Write a Lab Report. … Purpose: • The purpose of a lab report is to communicate the findings of your scientific study. Some thoughts: -improper measurement of string Instrumental errors can occur when the tools are not functioning exactly as they should be. The lab involves the demonstration of the process of the addition of several vectors to form a resultant vector. (note: in the full experiment you would react Mg with air, products are MgO and some Mg3N2; cool down, add water (this converts the Mg2N3 to NH3 and Mg(OH)2; then heat up again: this converts the Mg(OH)2 to MgO and H2O(g) 2. Because a lab report is argumentative – in that you are examining a claim and determining the legitimacy of this claim by producing and gather evidence – it is frequently a wise decision to conclude your report with the same technique you utilized for establishing your main point. The laboratory report is a formal report of the experiment performed. Experiment write-ups will be in the form of lab notebooks. However, they all usually follow a similar basic structure. When you are assigned a lengthy lab report, it is important to include a conclusion paragraph to sum up your procedures and results for your reader.
