Lab Write-Up
For your FORMAL Lab Write-Up you need the following sections. Next to the section is a description of the information that goes in it and relative length of each section.
Title: - Should be scientific and not "catchy." (i.e "Investigating the Effects of Caffeine on Blood Pressure" - - - Not "Does Java Give You the Jitters?")
Introduction: Usually about 1 page. It should highlight the scientific concepts needed to understand the lab. For this lab I would focus on the relationship between energy and EM radiation type, explanation of SPF, and the difference between the active ingredients. This info should come from your research and needs to be cited.
Materials List: A list of the materials, chemicals, equipment, etc. you used.
Procedure: A step-by-step, specific list of the steps you took to collect the data.
Data: Tables that organize your data. Highlight UNITS. Tables should have descriptive titles, especially when more than one is used. Example: Blood pressure readings for individuals who consumed varying amounts of caffeine.
Calculations: Examples of any calculation you used (i.e. averages, percentages, differences, etc.) As we do more complex labs with different calculation specific to chemistry, this section will change.
Results: Tables that organize the answers to your calculations. This section should highlight comparisons to your variables, but focus on the averages and not the individual trial data.
Discussion: THIS IS NEW. This section explains to the reader what your results mean. Which sunscreen was better? How do you know? Point out specific results and explain how they lead you to make these decisions. Is the difference a lot or a little. This usually takes about 1 or 2 paragraphs. The next part of the discussion educates the reader on what might have gone wrong during your lab. This is called sources of error. Again about a paragraph. Lastly, the discussion ends with a suggestion to fix the sources of error and/or improve the lab if it was repeated.
