Part II: Write a 1-page lab report using the following scientific method sections:
• Purpose
o State the purpose of the lab.
• Introduction
o This is an investigation of what is currently known about the question being asked. Use background information from credible
references to write a short summary about concepts in the lab. List and cite references in APA style.
• Hypothesis/Predicted Outcome
o A hypothesis is an educated guess. Based on what you have learned and written about in the Introduction, state what you expect
to be the results of the lab procedures.
• Methods
o Summarize the procedures that you used in the lab. The Methods section should also state clearly how data (numbers) were
collected during the lab; this will be reported in the Results/Outcome section.
• Results/Outcome
o Provide here any results or data that were generated while doing the lab procedure.
• Discussion/Analysis
o In this section, state clearly whether you obtained the expected results, and if the outcome was as expected.
o Note: You can use the lab data to help you discuss the results and what you learned.
Provide references in APA format. This includes a reference list and in-text citations for references used in the Introduction section.
Give your paper a title and number, and identify each section as specified above. Although the hypothesis will be a 1-sentence answer,
the other sections will need to be paragraphs to adequately explain your experiment.
When your lab report is complete, post it in Submitted Assignment files.
