Take Away Message for Week 4

To be honest, I am a little worry about my video. I feel like they did a very good job which give me a lot of idea. It is not very hard to create a video in iMovie  but it is hard to have some good questions to lead the students to think about the topic and what they need to learn. 

Before today's class, my  topic is Rivers of the World. However, I feel like my topic is hard to make a good video. Could you give me some advice? Should I change my topic?
