Identifying of an Unknown Substance
I need the chemistry post lab report as same as you did once before. The original prelab report you did and lab experiment details are attached in pdf. I also attached the Error analysis; you can use it for doing Errors and Improvement section. Also post lab instructions are given below that you need to follow for making report. Must provide 100% original work and references in APA.
Post lab Instructions:
Procedure and Materials REDO: Write what you actually did and the equipment used. This may have changed from the prelab portion, since you worked with you Lab Mates.
Observations: What did I observe?What did I find?
This section contains any and all tables and graphs with data you collected. You should also include all observations that occurred during the lab. If you have to perform calculations, they belong after all data tables and graphs
Claim: What can I claim to answer my beginning question(s) or the class beginning question(s)?This is where you answer the beginning questions and you give your results of the experiment. Your claim should be one or two sentences long.
Evidence: This is where you use your data to back up the claim you made. Justify why you made your claim. This involves analyzing your tables and graphs, internal and external sources to back up your claim.
Errors and Improvement:
What are at least two sources of error, weakness, or limitations in the lab design?
This refers to those aspects that would require a redesign of the lab, rather than simply redoing the lab. Unclean glassware, wrong calculations, and human error DO NOT count! Must include at least two.
How might I improve the lab design to account for the issues addressed above?
Consider better procedures and/or equipment that would enhance the accuracy and precision.
Reflection: How have my ideas changed?
How does this tie in with what you learned in class? How can you connect this lab to something outside of the classroom? Are there any new questions you have about the lab?
Work Cited:Where did I get my information from? Am I giving credit to my source? Use APA or MLA style. (Do not use Wikianswers or Wikipedia) One source should be the Collin Lab. Another could be your text book.
