5 paragraph essay discussion for your lab investigation: "Investigating evidence of chemical change" is due today. It should be typed.  If you do not have access to a printer, then you must write very neatly so I can read it completely.  This essay discussion is worth significant points, half the value of our last assessment.

 

Refer to the attached file for a guideline.  It is slightly modified from the version we looked at in class on Monday

Assessment on measurement, uncertainty, graphing, and analyzing graphical data today.

Notes are due today.  Make sure to include your review guide and make sure you finish your graphical analysis for the silvery metal from lab.

Finish this part of the review guide at home and include in your class notes that are due tomorrow.  Honors Chem needs to complete questions that ask about % error and greatest source of error.  General Chem students, you do not.

Study for the assessment and write your essay. 

 

Honors chem students, for homework you should try and complete the analysis of your graph from the review guide.  Determine the slope + percent inherent error, comment on how comfortable you feel with the accuracy of the result, and determine  the greatest source of inherent error.

For homework, finish graphing the mass volume data from our lab (your data together with the sample data included on the attachment.  Use different symbols for the two metals so they can be distinguished on the graph.  Don't connect any data points.  We need to discuss the relationship in class Tuesday.

Read and summarize (or outline) sections 1.3 through 1.5 of your textbook

Write a rough draft for your lab discussion on our experiment "Investigating evidence of a Chemical Reaction."  For your rough draft, only write the body paragraphs 1,2, and 3, not the introductory or closing paragraph. This is a very important homework in that it is worth 2 points today.  You will have a chance to share out with your small group in class. The guidelines for this essay are attached here

Study and prepare for the parallel assessment on physical properties and separation techniques

The two attachments go together, and they include review for Friday's Assessment (physical properties, separation techniques, and modelling). 

 We have been looking at techniques for separating mixtures based on observable properties.  Chromatography is one more widely used method to separate dissolved solutes from a solution. 

 Review chapter 1 in your text and complete questions 67-72 from pages 34-35.
