All right, what can i tell ya? We started off on are packet called 2D.3 Monitoring & Identifying Air Pollutants. We only did one page and that was the cover. Then we did another packet but it was a grey packet. It was called the Unit 2 D3 Content Reading Guide: Monitoring And Identifying Air Pollutants. The last thing that we did was 2D4 Developing Skills. If your not done on the last thing we did, it will be for homework.
