The Materials and Methods and results section should be written in the past tense, since your experiments are completed at the time you are writing your paper. Your lab report should include the following sections: Cover Page (0.5 pt)  Include the title of the experiment, name, group number, and the date on which the experiment was performed Introduction(1 pt)   Purpose of experiment Background Information Materials and Methods(2 pt)    Equipment Used Schematic diagram of main equipment used (if required ) Test procedure generally contains information on the physical nature of the experiment, such as the type of instrumentation used, the variables controlled and those that are not controlled, and any unusual conditions. Here is an example of a section of that type. The experiment was carried out with a Nicolet Fourier transform infrared (FTIR) spectrometer. The resolution of the spectrometer was set at 1 cm-1 for all spectra. The experiment involved the accumulation of a background spectrum which were subtracted from the spectrum of the sample to provide the response of the sample. The detector was a nitrogen-cooled cadmium-telluride detector. Each experiment resulted from the average 64 transient responses coadded, with the background spectrum being the accumulation of 64 spectra without the sample present. The data were analyzed by Fourier transformation using the software of the instrument. The data were saved to disk, and were subsequently analyzed with a spreadsheet program, in this case, Microsoft EXCEL. Theoretical values of the parameters were predicted by computation with the program GAUSSIAN. The section need not be long, but it should include everything about the experimental setup that the author thinks is important. retrieved from"https://www1.udel.edu/pchem/C446/example.pdf" Results(4 pt)     Present your data using text AND figures/tables.

Sieve Analysis
Introduction
Purpose of the Experiment
The experiment aimed to determine the grain size distribution in coarse grained soils
Background Information
Sieve analysis involves separating soil particle into different sizes (Verma, Akhtar, &
Shrivastava, 2017). The size of the soil particles in a soil sample determine how a soil is
distributed when subject to sieve analysis. So distribution is analyzed in a logarithm
graph that give the shape of a curve that helps in determining whether the soil is poorly
graded , well graded or gap graded. According to Das (2002), soil sieve analysis is
si...
