LABORATORY WRITE-UP GUIDELINES

☆
☆
☆
ALL write-ups will be completed using the Write-up Template found on the website.
The font and size of type should NOT be changed.
ALL Headings and Sub-headings NOT used for the write-up need to be deleted.
The lab is YOUR work! You will be collecting the data with a lab partner but the rest of the write-up is your
own. It should not Look or READ like anyone else’s lab!
TITLE

Should reflect the nature of the lab.
INTRODUCTION
 Give a short description of the main idea of the lab, including definitions of key terms in your own words. Also
include an explanation of how the lab procedures will help you learn the main concepts. It should be written as
if you are explaining it to a classmate who has never had a science course.

Example Introduction: The main idea behind the mitosis lab is the process of cell division. Cell division involves a
single cell copying its genetic material and then passing it on to new cells by splitting in two. The end result of cell
division is two new cells that are genetically identical to each other and the original cell that created them. The
mitosis lab involves looking at cells under the microscope to see the process of cell division and get a better
understanding of what is occurring in the cell at each step.
If applicable, include a hypothesis statement at the end of the discussion described above. The hypothesis should
be written as a statement, not an “I think” sentence.
Example Hypothesis: The flatworm will move toward the light when exposed to a light and dark source.
MATERIALS

Create a numbered or bulleted list of materials used.
METHOD
 Create a numbered step-by step set of detailed directions on how the lab was conducted, no personal pronouns.
RESULTS
Observations
Sketches/Diagrams
 Remember to leave room in your write-up to attach sketches/diagrams (glue stick or clear tape neatly).
 Drawing needs to be on UNLINED paper & should cover ¼ to ½ of the page, centered.
 Plan before starting – do you have enough room for labels & a title on your drawing paper?
 Labels should be on the right & left side, use a RULER, and DO NOT cross label lines!
 Color or shade your sketch.
Data Tables:
 Each data column needs to have the same values – all in minutes or seconds, but not both in a column.
 Headings of each column should include the units. Example: Time (minutes).
 The Title needs to be on top of the table and it should be clear as to what the table is showing.
Calculations:
 Write down equation(s) used.
 Neatly show your work.
 Include units & circle or box your final answer.
Graphs:
 Graphs should be at least ½ page in size
 If you are unable to use the computer to make a graph, use graph paper & attach to your lab in the Graph
Section – be sure to leave room!
 Label the X axis and Y axis. Include units in parentheses. Example: Time(sec.)
 Place the title above the graph – it should describe what the graphs is displaying (x axis vs. y axis)
QUESTIONS (Follow the directions on the template)
CONCLUSIONS

This is the MOST IMPORTANT part of the report. This is where all of the results are interpreted. Spend some
time thinking about what the calculations, graphs or drawings are indicating. Follow the steps on the template
to complete the conclusions and use complete sentences.
