On Friday, we performed an experiment to determine the melting point and boiling point of water.
The homework for this weekend is to write a lab report about the experiment. The format can be found on the back of your Safety Procedures packet, but here are some clarifications:
Purpose: This section should be 1-2 sentences, beginning with “The purpose of my research was…” This is also where you will include your hypothesis in later lab reports.
Procedure: Here you will refer back to the procedure from the lab handout and note any changes. My favorite way to write these sections is to start off with “The protocol was followed as presented in the lab handout, with the following changes… (explain). Briefly … (summarize the procedure in 2-4 sentences)”
Data: Attach any data you collected in the experiment. You can attach your handwritten data from class, or you can retype it in in Excel or similar.
Calculations: Put your graphs and any other calculations you have here.
Conclusions: Here you will answer the question that drove your research. You will address your hypotheses as well. This week you might have something like “The melting point of water was determined to be … The boiling point of water was determined to be …” If there was a problem with your experiment, explain it here. If there was a major source of error, explain that as well.
Questions: Most labs will have 3-4 guiding questions to answer. Put your answer to those here. Note that there is a typo in question 1 from this week. It should read “According to your data, what are the melting and boiling point of water?”
If you did not get a full set of data, you can either explain what went wrong, or use this data:

I will have an example report posted tonight. I apologize for the delay, but I am having technical issues.
Makeup homework:
Hypothesis: here is the link again, with the typo fixed http://quin60.wix.com/whsad-chemistry
Survey/Contract: Either turn it in Monday or write a half-page summary of the rules, requirements, and expectations for Monday.
Have a good weekend!
