It is important that you understand the purpose of the lab, how a problem can
be tested, and how to record and interpret results.
Laboratory exercises are not optional. If a student misses a lab, he/she
will be required to make up the lab at the teacherís convenience.
Title of Lab
Date(s) of the Experiment
Your Name and the Date of Report
(List your partnersí names.)
Purpose/Introduction: Give the background for the experiment. Describe
what you already know from reading in your text or other literature or the
handout for your experiment. In a sentence or two, describe/explain what youíre
going to try to find out. State a hypothesis clearly stated in terms of
independent and dependent variables.
Methods/Materials: Usually a clear, concise REPEATABLE description of
method and materials is given. You may list materials. For these experiments,
you are given a procedure. Do not copy the procedure. In a paragraph, SUMMARIZE
the method. Include the main steps. Provide sample calculations.
Results: Data and data analysis is placed in results. Data should be
presented in chart or graph form. All charts and graphs must have a title.
Columns and rows of charts should be labeled. Axes of graphs should be labeled
and units given in the label (e.g., Time minutes). Any data manipulation, such
as equations or calculations, should be included and explained briefly.
Discussion of results is a concise interpretation of the results. If you present
a chart, explain the results. If you include a graph, interpret the findings.
Conclusions: Summarize and explain the main findings of the lab. Use your
introduction and your charts and graphs to help explain your results. If you did
not get anticipated results, identify possible sources of error and/or explain
why you think you got those results. There are specific questions in the lab
handouts. Answer those questions in this section. If your results do not support
your hypothesis, propose a new hypothesis.
LAB REPORTS SHOULD BE TYPED. Graphs may be done by hand. Labs are PLEDGED.
LAB REPORTS ARE DUE 4 SCHOOL DAYS FROM THE DATE OF THE CONCLUSION OF THE LAB.
For example, if a lab is started on a Monday, completed on Tuesday, the lab
report is due the following Monday. Exceptions to this policy will be announced
at the onset of the lab procedure. Lab reports may be turned in early. Late
reports will lose a letter grade/day.
