PostLab Instructions

Procedure and Materials:  Write what you actually did and the equipment used.  This may have changed from the prelab portion, since you worked with you Lab Mates.(for procedure, please do not copy form chemistry hand out)

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.
