Datalogger Experiment

The datalogger can be used for testing unseen substances. Like: Heat, Gas, etc. We used the gas sensor for the experiment. It turned out that our leaf gave out CO2 when they photosynthesised. Firstly, we adjusted the time to automatically stop after 30 mins, next, we put a leaf in a jar. Third, we put the sensor on the jar, like a lid. The leaf was not from our own sunflower. It was from the additional sunflower that were grown. Our sunflower's leaves were too small. We observed the chart of the datalogger. We forgot that the sensor was not supposed to be on the lamp, as it was too hot. So we restarted everything. The graph showed that carbon dioxide levels were decreasing after a while. After half an hour, we saw tiny water droplets on the inner surface of the jar. So, plants give out water vapour which caused the 'misting'.
