Hi ! This is Dominic B. from 6th period. I hope you get this answer soon, seems like my last post took a while. Q1: The co2 is about 386-388 PPM. Q2: I think this data was either in the early morning or late night because of sunlight. I think the level of co2 will rise in 2 hrs. because sunlight will cause more photosynthesis.
P.S. The class can't wait 2 see u again :) Dominic
