LAB REPORT TEMPLATE
Title:
A brief concise, yet descriptive title
Statement of the Problem:
What question(s) are you trying to answer?
Include any preliminary observations or background information about the
subject
Hypothesis
Write a possible solution for the problem
Make sure this possible solution is a complete sentence
Make sure the statement is testable
The statement should reference the independent and dependent variables: such as
“The plant group receiving (independent variable i.e. fertilizer) will (dependent
variable i.e. produce more fruit) than the plants that did not receive (independent
variable i.e. fertilizer)
Materials:
Make a list of all items used in the lab
Procedure:
Write a paragraph or a list which explains what you did in the lab.
Your procedure should be written so than anyone else could repeat the
experiment.
Results:
This section should include any data tables, observations, or additional notes you
make during the lab.
Although some students may wish to recopy original data: it is important to
always preserve the orginal
You may attach a separate sheet(s) if necessary.
All tables, graphs and charts should be labeled appropriately.
Conclusions:
Accept or reject your hypothesis
EXPLAIN why you accepted or rejected your hypothesis using data from the lab.
Include a summary of the data – averages, highest, lowest, etc. to help the reader
understand your results.
List one thing you learned and describe how it applies to a real-life situation.
discuss possible errors that could have occurred in the collection of data
(experimental errors)
