Cabon+Dioxide+Lab

Sten Mander and I, John Shribbs, have created some worksheets for labs on CO2 using PASCO probes. These labs were done with the help of Jim Callahan of ClimateChangeEducation.org and Jeff Arrigotti of PASCO. We wanted to include CO2 output comparison from human **respiration** and engine **combustion**, CO2 uptake and O2 output by plants during **photosynthesis**, and **ocean acidification** showing solubility in water by pH indicator dye. We also took videos of students doing the work, which are embedded below.
