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.
