See the presentation outline below for report content. I am happy to review drafts. The lab reports are due at the beginning of lab on 10\/25.<\/p>\n 2) Each pair of students should prepare a poster presentation to the lab group on your analytical method. Both students should be prepared to give the presentation. We will use a suitable random number generator to determine which student will present the lab results.<\/p>\n The presentation should include:<\/p>\n Total time with questions should be 15 minutes.<\/p>\n We will have our poster presentations in Keyes 104 at the start of the lab period. Please test your presentation in this room before the start of lab.<\/p>\n I am happy to review presentations before you give them. \u00a0This is a good idea!<\/p>\n<\/div>\n Please consider\u00a0the following\u00a0excellent resource on preparing scientific talks.<\/a><\/p>\n 10\/25\/2018 \u00a0 – \u00a0Presentation of Field work and, \u00a0<\/strong>Simple Photometer<\/strong><\/p>\n Source Data Sheet:\u00a0 SloanLED<\/a>\u00a0(red, green, blue light source) <\/a> CH 331 CA-EDTA LAB 2015<\/a><\/p>\n The report for this lab should be in the same format as earlier lab reports (see above) and is due in lab on Wednesday, 11\/15.<\/p>\n 11\/15\/2018 – Working with Ion Exchange Columns<\/a> \u00a0<\/strong><\/p>\n 11\/29\/2018 – Silver Ion Selective Electrode<\/strong><\/p>\n Silver ISE 2016<\/a><\/p>\n TBD – Cyclic Voltammetry and Rotating Disk \u00a0Voltammetery<\/strong><\/p>\n Ch 331 rotating disk exp<\/a><\/p>\n Supporting documents<\/a><\/p>\n <\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":" Laboratory Materials for Chemical Methods of Analysis Links to labs: 9\/13\/2018 \u00a0Introduction to Great Pond. 9\/20\/2018 :\u00a0CH331 Lab 2: Preparing Solutions and Calibration. 9\/27\/2018 and 10\/4\/2018 \u00a0Developing analytical methods for\u00a0lake water analysis 10\/11\/2018 \u00a0–\u00a0Lake Sampling 10\/18\/2018 – Analysis of … Continue reading Field data taken at\u00a0Goldie on\u00a0Great Pond.: \u00a0Posted after data collection<\/h4>\n
No formal lab writeup this week. \u00a0 Plot both sets of temperature data against a common Y axis (in oceanography, limnology and atmospheric chemistry the Y axis is depth or altatude and is treated as the independent variable), Please use the appropriate t-test to compare the temperature profiles taken using the YSI Sonde and Goldie’s thermister chain. \u00a0At the 95% confidence level are the two measurements different (see box 4-1 in your text)? – due at the start of lab next week.<\/h4>\n

\n2) Bring a pen and calculator.
\n3) Please wear closed toe shoes and don’t bring your book bags into the lab.
\n4) Prepare for lab before the start of lab. We will begin lab with a short lab quiz. You may use only your lab notebook and calculator during the quiz. Attached below you will find links to three documents.<\/p>\n
\nYour grade will be based on your ability to meet the concentration target.<\/p>\n
\nInstructions for your specific pH meters will be available in lab. Reports should be based on The American Chemical Society Style Guide<\/a>\u00a0(Look for information for authors and document templates) and\u00a0will be due at the start of lab next week
