In past classes. First I have to see the videos that are related to global warming, whether it is the cause and effect change. Also, learn more about the changes in the world. Where is the knowledge that, in addition to regular classroom learning, such as the movement of plate tectonics? The flow of water in the ocean.
Later, The fault is my knowledge of the terminology, such as those with greenhouse gases. The atmosphere, etc.
And finally, What I expect is that I hope I will get to know that apart from the textbook and learning new vocabulary and more.
