EAHS Science Lab Report Format
(This is the format that all EAHS science teachers will be using)
Include the initial question you are investigating or the problem you are trying to solve.
The title should be centered or left-aligned on the top line of your paper.
INTRODUCTION/PURPOSE: (1 or more paragraph)
Express the purpose or reason for doing the experiment as well as will include a brief summary of any relevant concepts and content vocabulary.
The introduction/purpose should be written in paragraph form.
HYPOTHESIS (CLAIM): (1 Sentence)
A hypothesis (claim) is a testable, verifiable, refutable explanation of the initial question or problem.
Describe WHAT you EXPECT will happen in your experiment and WHY you think it will happen. (Include the Independent Variable (IV), Dependent Variable (DV) in your hypothesis when possible.)
Always write your HYPOTHESIS BEFORE beginning your experiment!
Write your hypothesis in one of the following formats:
3. a detailed testable explanation or statement
MATERIALS: (bulleted List)
List all the equipment, chemicals or other substances you need to do this experiment. (Be specific about what size containers you will be using and how much you need of each substance.)
Materials should be written in a bulleted list in one or more columns.
EXPERIMENTAL SET-UP/PROCEDURE: (list of numbered steps)
Explain exactly what will done and how it will be done. (Another person should be able to replicate your work by following your procedure!)
How will the experiment be performed? What will be measured? How will it be done?
What will be observed? How will it be done?
Write procedure in a clear, numbered list (1., 2., 3….)
Qualitative Data: (bulleted list)
LIST any and all things that you notice before, during and after your experiment. Use your senses of sight and sound. (Only use your sense of touch and smell if it is safe.)
Write qualitative data/observations as a bulleted list.
Quantitative Data: (tables, charts, graphs)
Use tables, charts, graphs and/or drawings to represent your quantitative DATA. All graphs must be done on graph paper.
All tables, charts, graphs and/or drawings need to be properly LABELED with correct values, units, scaling and titles/headings. Add color to all drawings and charts/graphs when appropriate.
DATA ANALYSIS: (1 or more paragraphs)
Analyze your data for relationships between variables (including patterns, trends and outliers). Discuss what these relationships might mean.
Refer back to your graphs and/or calculations. Specifically discuss data numbers with correct units.
Evaluate whether your data is valid. Were there any flaws in the experiment? What are the possible sources of error?
Write Data Analysis in a PARAGRAPH/SHORT ESSAY FORMAT.
CONCLUSION: (1 or more paragraphs)
Review your original hypothesis and make a CLAIM that accepts or rejects your hypothesis.
Example: After the experiment, I accept my hypothesis because the pillbugs preferred the dark.
Example: After the experiment, I reject my hypothesis because pillbugs preferred the light.
Example: After the experiment, my data was inconclusive as the pillbugs showed no preference for light or dark.
Provide EVIDENCE from your analyzed data/observations that specifically supports or refutes your hypothesis/claim. (Refer back to your graphs and/or calculations. Specifically discuss data numbers with correct units.)
Provide REASONING discussing why or how the evidence supports your claim
Discuss what you learned,what you are still curious about and what new questions or hypotheses were inspired.
Write Conclusion in a PARAGRAPH/SHORT ESSAY FORMAT.
LAB REPORT QUALITY: ALL FORMAL LAB REPORTS need to be typed (12 pt. font/normal margins) or written neatly in blue/black ink.
