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

Checking on our sunflower 150409

Thalia:I saw no colour on the petals but the stem had a bit of colour i think the petal did not have colour because the stem was not long enough.
Lim Yong Zhang:I did not see any changes. :P :{ :[ .............................
our prediction:No! our outcome was not the same as our prediction. We thought that one side would be red and one side would be blue

If we have a chance to do it again, we will cut the stem properly.
