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!

Hi Jing Yun and Jia Yun,
ReplyDeleteGood to hear that you find the datalogger interesting. Hope you have learnt something useful from it.
Why do you think there are water vapour at the side of the bottle after 20 minutes? What process do you think have taken place?
