Hey Mr.Wood, This is Victoria Shubin from P.1. #1. It is showing 243 CO2.

2.I think the time of day is night time because the charts that Mr. P showed us the night chart and it looked really calm like the one now. 3. I think it will go down because the coldness will maybe over power the CO2 during the rest of the night.
                                                                       Thank you,
                                                                                     Victoria Shubin :)

Good thinking but remember that the plants are taking in CO2 in the sunlight during photosynthesis. Thanks for the answers.Mr. Wood
