1. APES 3/1 and 3/2 Please get a laptop and pull up your Module 62 organizer for check-off Share your 5 minute presentation with me

2. Indoor Air Pollution Notes! Order: Radon, Asbestos, VOCs, Pollen/Mold, CO

3. Indoor Air Pollution Lab 1.Hold the sensor straight up towards a light, 5 feet off the ground. 2.Wait until you get a baseline reading 3.Put the control tape directly against the sensor and record a reading 4.Put your air pollution samples directly against the sensor and record readings 5.For each sample, calculate a percent change in absorption from the control tape Original # - New # x 100 Original #

4. Module 62 Multiple Choice 1.D- CFCs have the highest global warming potential, followed by N 2 O, methane, carbon dioxide, and water 2.A- methane is naturally produced by decomposition (also by digestion) 3.A- absorption AND re-radiation of infrared (heat) radiation by greenhouse gases cause the greenhouse effect 4.B- most N 2 O release is from agriculture (fertilizers, etc.)- next is from combustion 5.E- particulates can lower surface albedo (ability to reflect light); earth reflects more heat

5. Due next time… Module 63 and 64 organizers (online)
