How to Write a Lab Report H. Chemistry 2012
General Information • Do not use “I”, “you”, “we” in your report. • Write from an objective point of view. • Use past tense when writing all parts but introduction. • Do not say how much you learned or enjoyed the lab. • You are writing the report so that ANYONE can follow it.
Title • Not wordy • Concise, yet informative
I. Introduction • Should give background information on the laboratory topic. • Example: Annelid Regeneration • Introduction should include information about the specific Annelid used as well as regeneration. • Use different references! (Cite them!)
II. Materials & Methods • Materials • List all materials used in experiment. • Methods • List step sequentially. Give details! Use past tense.
III. Results • Includes tables and figures • Data tables are important here and graphs where appropriate • All have titles & captions so they “stand alone”
Ex. Graph :Termite Survivorship Figure 1. Mean percent survivorship of R. flavipes (Kollar) when fed hexaflumuron Noviflumuron or untreated cellulose matrix for 2, 4, or 6 wk.
IV. Discussion • Refer to figures & tables chronologically. Did you reject or NOT reject your hypothesis? Conclusion of the lab. • At 20 C there was no significant difference in survivorship among treatment groups at 2 (t = -0.02, df = 8, P = 0.98; t = 0.52, df = 8, P = 0.60; t = -0.5, df = 8, P = 0.62) or 4wk (t = -0.72, df = 8, P = 0.48; t = -1.42, df = 8, P = 0.16; t = -0.71, df = 8, P = 0.48) (Fig. 2). Hexaflumuron-fed termite survivorship was not significantly different…..
