LAB REPORT FORMAT
Provide a title that is a description of your lab followed by a lab number. The title should clearly identify the experiment’s variables (independent & dependent)
This is the place to explain what you are trying to find out or what you are going to do in the lab.
Include information about the variables involved.
This is a cause/effect statement.
This is a prediction of what the expected outcome of the lab will be. Relate the hypothesis to the purpose/problem of the lab.
Try to focus your hypothesis on the information/research you collected.
List all items in a column.
Make sure to record the exact size and amount of each item required.
List and number each step.
Use complete sentences (begin with a capital letter and use end punctuation). Should be clear enough for someone else to use as instructions for repeating your experiment.
Be sure to accurately record your observations/data in a chart or table. Create a graph to provide a visual of your data.
Provide a verbal description of your data.
List all quantitative (numbers) and qualitative (words) data. List all variables and explain what your control was.
Match your conclusion to the purpose or the problem.
Base your conclusion on your analysis of your observations and any data that has been collected.
Explain: (The following are just suggestions and DO require elaboration.) o What you did in the experiment
o What you observed (trends/patterns in your data that supported or did not support your hypothesis)
o What you learned from the lab
o If you think it was a fair test (i.e. – was there anything that may have impacted the accuracy of your results)
o Questions for further research and investigation
o Application: Can you think of an analogous situation that applies to real life?
All sections (Title, Purpose, Hypothesis, etc…) should be labeled as shown above.
SAMPLE LAB REPORT
Title: The Effects of Increased Activity on a Person’s Heart Rate - Lab #1 Purpose/Problem: To understand what happens to a person’s heart rate as they increase their activity level. Hypothesis: If a person increases his or her activity level, then their heart rate will increase due to the body’s cells increased need for oxygen.
1. Find your heart rate by placing two fingers on your wrist. 2. Count each thump as one beat.
3. Sit in your chair. Have your partner time you for 60 seconds as you count the number of beats. This represents how much your heart beats in one minute while you are resting. Record this number in your data table. 4. Stand up. Have your partner time you for one minute as you walk around the class. At the end of one minute, continue to walk in place as you take your heart rate for 60 seconds. Record this number in your data table. 5. Repeat step number four while this time running in place instead of walking. Record this number in your data table. 6. Repeat steps one through five with all members of the group and record all data. 7. Find the average heart rate for each category and record it in the data table. Observations/Data:

The average resting heart rate was 80 beats per minute. When activity levels increased due to walking, the average heart rate rose by 22.5 beats to 102.5 beats per minute. Finally, when running, the average heart rate increased by 47.5 beats to 150 beats per minute. This increase in activity level represented the...
