Objective




Describe objectives of the experiment
Describe what you are setting out to do. What problem needs to be solved
Do not copy anything directly from the lab sheet! Use your own words.
No more than a paragraph
Materials
 Make a List of materials
o Pictures of materials are extra credit
o 1 picture per material
Methods (you started at procedure 2 so your procedure # 1 is the Lab’s # 2)
 Write a step by step description of your procedure
 If you changed your original procedure or had to do something you didn’t expect to do, you
must include this information.
 Do not include any results, conclusions, or explanations in the procedure
