1 Moday April 13 Due today: Spectrophotometer and Beers labs Objectives: Light and energy demo and calculations Homework: Finish Light and energy worksheets (2 of them) – due block Finish Light and energy POGIL – due block Prep Flame test lab – due block Finish light and energy test review due Friday (day of test) DQ: NA Handouts: Light and energy worksheets Coming up: Tuesday – work day; Block Flame test; Friday Light and Energy/Net ionic test Extra Credit Opportunity: May 20 6:30 (set up) 7-9 program. Opportunity for Honors Chem parents to see to STEM projects and for everyone to see Believe in Ohio projects

2 Block April 15-16 Due today: Light and energy worksheets and POGIL Objectives: Flame test Homework: Finish light and energy test review due Friday (day of test) Study for test!! DQ: see handout – complete and bring to Mrs. B to check 1.What is the best wavelength to dial into a colorimeter to measure absorbance? 2.If I measured an absorbance of.45, what is the concentration? Handouts: Na Extra Credit Opportunity: May 20 6:30 (set up) 7-9 program. Opportunity for Honors Chem parents to see to STEM projects and for everyone to see Believe in Ohio projects

3 Choosing the appropriate color/wavelength when using a colorimeter Students should choose the wavelength of light that corresponds to the wavelength of visible light that absorbs the maximum number of photons for a particular solution. This wavelength can be estimated by choosing a wavelength of light that represents a color that is opposite in color from the solution color. See Diagram: Red Orange Violet Yellow Blue Green

4 FridayApril 17 Due today: Light and energy Test Review Objectives: Ace light and energy test Homework: Finish flame test lab Cornell notes Pgs 309-310; 315-316; 318-325 - due next Friday DQ: NA Handouts: Na Extra Credit Opportunity: May 20 6:30 (set up) 7-9 program. Opportunity for Honors Chem parents to see to STEM projects and for everyone to see Believe in Ohio projects
