LimYongZhang:I used the data logger to measure the amount carboon dioxide and we started putting the leaf and one of the girls blew into the jar and quickly covered it with the datalogger and the graph showed the amount of carboon dioxide..............................................................................
Thalia ng: We used our sunflower leave then we put the leaf into a bottle then I blew carbon dioxide into the bottle ,than we covered the bottle up then we switched on the datalogger ,the datalogger will help to measure the amount of carbon dioxide. I hope that I can use the datalogger again
