What materials are necessary to perform this experiment?

What are the steps, in order, that you must do for everything to turn out right?

This should be in enough detail that others could perform the lab and get good results.

A good clear photo with a caption can save many words in this section.

Worth 15 points


Tables or charts are best.

Did the experiment do what we wanted it to do as written under the purpose section?
Did the lab function properly, or were the problems so bad that you cannot conclude anything from the experiment?
Can you apply this in the real world?

Is there a general rule or law that we can observe.
How does this relate to the theory covered in class and lecture?
Worth 10 points

Staple your actual laboratory notes, data sheets to the back of your lab report.


Do not rewrite or tidy up your laboratory data sheets/notes.

This is your proof that the lab was conducted, not downloaded from website.

(It is implied that all students contribute to collecting data, and write down results as the occur in the lab.)

Worth 10 points


Whenever I ask for a complete lab write up please include all of the sections listed above. A short summary of what should be in each section is on the left. If the lab is non-numerical or a % error cannot be calculated for example, those points will apply to the section as a whole. As always, typed lab reports earn 5 points of extra credit.
