Geo lesson for 2nd.Feb! ^^
When today`s lesson just started, Mr.Heah tried to remember our names.~_~And then was the revision part. We reviewed some points including composition of atmosphere, function of Oxygen Carbon dioxide and Nitrogen.
Following we talked about systems equilibrium and regulatory forces witch include positive and negative feedback, positive feedback will cause encourages change while negative one will cause discourages change.
Next is the most important part we had for this lesson: Carbon Cycle! "What is the impact of man on carbon cycle?" Mr.Heah said it was very important to ASK QUESTIONS ABOUT THE QUESTION! So we need to consider about "What is/are the impacts?" and "What is carbon cycle?". And here are the mind map of carbon cycle.:)
Umm sorry maybe not clearly enough...

Ok that`s all for today.
