Industrial Hygiene Lab
Introduction (Theory)
In this section the students have to use their own word to describe the theoretical concept behind the experiment. The content should not be copy/pasted from the text books. The following tips needed to be followed:
Use passive sentences
The sentences must be in third person form
Do not put any numbers that is measured during the lab session in this section
Use any reference (textbooks, handbooks, peer-reviewed papers) in order to provide a comprehensive explanation about the theory. (commercial websites and documents are not accepted)
Scan or draw and insert any graph, pictures or figure into the text that helps understand the subject
The pictures/graphs/figures need to be numbered and numbers should be sequential and followed by a foot notes.
Different pictures/graphs/figures should not have same number
In the text, pictures/graphs/figures need to be referred to by corresponding numbers
Figure 1 – picture description
Do not forget that the goal of writing lab report is to provide a document on how an experiment was done so that others can follow the instructions and replicate the experiment and get the exact same results.
Necessary formulas can be inserted here.
A=πr^2 (1)
The formulas need to be numbered
Numbers should be sequential
Different formulas should not have same number
In the text, the formulas need to be referred to by corresponding numbers
Objectives
In this section the students should explicitly state the objectives and goals of the experiment. It can be a demonstration, or measurement or observation. The goals can be explained briefly.
Instruments and Materials
In this section the instruments used in the experiment needed to be explained. The following information should be included in the report but students should not limit themselves from additional details.
The number of each instrument
The measurement range and accuracy of each device
Materials and their amount being used in the experiment
The picture of instruments and materials can be inserted in the text but not required/necessary.
The pictures need to be numbered
Numbers should be sequential
Different pictures should not have same number
In the text, pictures need to be referred to by corresponding numbers
Methodology
The methodology is a step-by-step explanation of how the experiment was done. It should include, but not limited to, the following information:
The setting of the experiments
Dimensions (if applies)
Timing (if applies)
Initial setups and values
The units must be clearly mentioned
All unit conversions must be explained and the calculation must be written
Figure 2 – an example for general setup
Scan or draw and insert any graph, pictures or figure into the text that helps understand the experiment
The pictures/graphs/figures need to be numbered
Numbers should be sequential
Different pictures/graphs/figures should not have same number
In the text, pictures/graphs/figures need to be referred to by corresponding numbers.
The students can write all the reading and measurements in this section. It is strongly recommended to write the numbers in a very organized manner, such as tables.
Table 1 – add a title here
Parameters Condition 1 Condition 2 Condition 3
Distance X, m 10.1 12.4 13.2
Distance Y, m 5.8 4.2 6.1
Time, s 12.5 11.8 11.3
Weight, Kg 0.5 0.5 0.5
The tables need to be numbered and numbers should be sequential
Different tables should not have same number
In the text, the tables need to be referred to by corresponding numbers
℃=(℉-32)/1.8 (2)
℃=(85-32)/1.8 (3)
℃=29.4 (4)
Necessary calculations can be inserted in this section.
The equations need to be numbered numbers should be sequential
Different equations should not have same number
In the text, the equations need to be referred to by corresponding numbers
Results
In this section students need to write the results of the experiment and calculations and etc. If some explanations are needed in order to make it easy to understand the results, such as exceptions, conditions and assumptions, they must be explained in this section.
Table 2 – add a title here [it should be in on the same page entirely]
Parameters Initial conditions With Heater With Fan
Analog System
WBGTin 32.3 ℃ 38.9 ℃ 35.1 ℃
WBGTout 32.8 ℃ 39.1 ℃ 36.2 ℃
Digital System
WBGTin 32.8 ℃ 39.4 ℃ 35.6 ℃
WBGTout 33.4 ℃ 39.9 ℃ 36.8 ℃
Do not make any specific conclusions
It might be needed to represent results in form of tables, graphs, charts, pictures or etc.
All tables, graphs, charts, pictures need to be numbered
Numbers should be sequential
Different tables, graphs, charts, pictures should not have same number
In the text, tables, graphs, charts, pictures need to be referred to by corresponding numbers
The entire table, graphs, figures and etc. should be in the same page and not divided into two pages.
Note: The numbers in able 2 are hypothetical and are not the actual results of the any experiment. Any similar numbers are coincident.
Conclusion
Students need to make conclusions at the end of each lab report regarding that how and why changing each condition during experiment affected the results.
Students also need to suggest and explain some other parameters that can affect the results of their experience which were not considered in the experiment. In other word, they need to provide list of parameters that can cause errors in their experiment and explain them.
Acknowledgement
If students are using some of the materials of other classmates (such as pictures or data), they should state it in this section.
References
If any references have been used to prepare this lab report they should be listed here. All references should be cited in the lab report.
