Monday, Dec. 3rd: “A” Day Tuesday, Dec. 4th: “B” Day Agenda Homework questions/problems/collect Video: “Elemental Funkiness” Quiz over section 4.2: “Tour of the Periodic Table” Lab Discussion/Write-up: “Flame Tests” Periodic Table Project/work time Homework: Finish lab write-up We will be in the lab next time, be sure to dress appropriately! Homework 1. Pg. 131: #1-12 2. “Elemental My Dear Watson” worksheet Problems? Questions? Section 4.2 Quiz “Tour of the Periodic Table” You may use your notes and/or your book to complete this quiz ON YOUR OWN. #9 Correction: Change d orbital to s orbital Change s orbital to d orbital Pick up a copy of the flame test lab and start reading it through when you turn in your quiz. Good Luck! Flame Test Lab Partner Your partner for the flame test lab will be…… Lab: “Flame Tests” Discussion Remember, when energy is added to an atom, electrons can move from the ground state to an excited state. Electrons are unstable at the excited state and will “fall back” to a lower energy state. When the electrons “fall back”, specific wavelengths of light will be emitted that can be seen as different colors. Each element has it’s own unique lineemission spectrum. Lab: “Flame Tests” Discussion In this lab, you will be testing various metal solutions and recording the colors of the flames that you see. Samples will be set up at the lab tables and you and your lab partner will rotate through the stations. After testing all of the known samples, you will test 2 unknown samples and try to determine what metal elements they contain by comparing their flame color to the color of the flames of the known samples. Lab: “Flame Tests” Changes to Materials List and Data Table Changes have already been made to the materials list and data table before copies were made…. You’re welcome! Lab: “Flame Tests” Procedure Discussion Work through the handout and use the data table as a guide. Sometimes you will view the flame through cobalt glass, sometimes you will test a mixture of metal solutions. To test the NaCl crystals, remove a wooden splint from the beaker of distilled water and dip it into the beaker of NaCl crystals. Be careful not to keep the wooden splint in the flame too long; it is wood and it will burn! Lab: “Flame Tests” Write-up Work with your lab partner to complete the lab write-up: 1. Title 2. Purpose 3. Hypothesis 4. Materials 5. Procedure Remember to update the table of contents in your lab folder! Periodic Table Project I wanted my chem 1 classes to make their own periodic table. But, instead of just having everyone use a white sheet of paper, I thought it would be neat if everyone made an element “square” using google docs and then sharing it with me. If everyone makes 2 squares (including me) we’ll have all 118 elements of the table represented. All the squares will then be compiled into a Chem 1 periodic table of awesomeness! Periodic Table Project You will use an app on the Ipads for data collection and computers in either the library or computer lab to make your squares. You will have the rest of the class period today as well as half the class period on either Friday the 7th or Monday the 10th – use your class time wisely! You will have 2 weeks to complete the squares, which will be due on: Monday, Dec. 17th: “A” Day Tuesday, Dec. 18th: “B” Day
