pair 14 datalogger

Jing Yun: Using the datalogger is very fun and interesting. We used the datalogger to measure the amount of carbon dioxide.
Jia Yun: Before we put the datalogger, we softly blew air inside the bottle. After 20 minutes , I found out that water vapour existed at the side of the bottle! YAY!

Checking on our sunflower 150409

observation

Jia Yun: Our flower did not change at all, we have already done our best.
Jing Yun: When we went there during recess, the flower did not change colour. So sad. :(
If we are given a chance to do it again, we will try not to put scotch-tape and we must cut it into half properly, inorder to let it balance! :)
