Hey Mr. Wood!

For the questions in your journal I got the following answers.

  1. The CO2 in the graphs are between 386 and 388 parts per milliiom

  2. The data was collected in the evening

  3. The carbon is less at night because the plants arent using photosynthesis

Thanks alot! --- Noah Glass Period 4 science

Thanks for the answers. Good thinking, but remember that during photosynthesis the plants are using more CO2 and giving off oxygen.Mr. Wood
