Shalini:We actually needed to find about the amount of carbon dioxide in the bottle.
Edwin:I think the experiment was a sucess。
Shalini:We put a leaf in a bottle。Then,we switched on the light and i gently blew inside the bottle。Then,we put the gas sensor inside the bottle。
Edwin:We set the dataloger to 30minutes and we waited for 30 minutes。After about 15 minutes, water droplets could be seen。The leaf absorbed the carbon dioxide blew by Shalini and gave out oxygen。
Shalini:The graph on the dataloger showed that the carbon dioxide was a lot
at first but the leaf absorbed the carbon dioxide and decreased。

I can see that both of you had enjoyed your datalogger lesson. Glad to hear that the experiment was a success!
ReplyDeleteWhy do you think that the leaf absorbed the carbon dioxide? Make a guess!
Miss Lee :)
Edwin:To Photosynthesis
ReplyDeleteShalini:To see how photosynthsis takes place
