Part II: Write a 1-page lab report using the following scientific method sections: 

• Purpose 

• State the       purpose of the lab. 
• Introduction 

• 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 

• 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 

• 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 

• Provide here       any results or data that were generated while doing the lab procedure. 
• Discussion/Analysis 

• In this       section, state clearly whether you obtained the expected results, and if       the outcome was as expected.
• 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.
