Lab Report Template BY Mr. Rose
3
Title: Brief Concise yet descriptive
For example: surface tension of water.
4
Statement of the Problem:
What question or questions are you trying to answer? Include any preliminary observations or background information about the subject For example: How many pennies can a full glass of water hold before it runs over?
5
Hypothesis: Write a possible solution for the problem.
Make sure this possible solution is a complete sentence. Make sure the statement is testable. For example: The full glass of water will not hold more than ten pennies if they are carefully dropped in.
6
Materials: Make a list of ALL items used in the lab.
For example: water drinking glass pennies
7
Procedure: Write a paragraph (complete sentences) which explains what you did in the lab. Your procedure should be written so that anyone else could repeat the experiment. A labeled diagram can be helpful.
8
Results (Data): This section should include any data tables, observations, or additional notes you make during the lab. You may attach a separate sheet(s) if necessary. All tables, graphs and charts should be labeled appropriately.
9
Data table Trial 1 Trial 2 Trial 3 averages 21 pennies 22 pennies
23 pennies

11
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
12
Conclusion contd. 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 the data (experimental errors).
13
Cohesion Water molecules are attracted to other water molecules. The oxygen end of water has a negative charge and the hydrogen end has a positive charge. Both hydrogen of one water molecule are attracted to the oxygen from other water molecules. This attractive force is what gives water its cohesive properties.
14
Surface Tension Surface tension is the name we give to the cohesion of water molecules at the surface of a body of water. The cohesion of water molecules forms a surface "film" or “skin.” Some substances may reduce the cohesive force of water, which will reduce the strength of the surface “skin” of the water.
