Reflection on Task 3

It is good to work with a partner. Qingchun helps to enrich the ppt presentation by establishing the context of raindrop formation. She put a series of images into one slide. However, I want the primary slide that explains the process of the breaking-up of a rain drop to have interactive device so that the student may interact with the proponents of the promary slide. I don't know how to do it, therefore, I use a stupid method to present my idea but it works. If you want to know how I do it, you could check it out from the following link:

I appreciate if you could show me how to make it simplier. Thanks!
Remember! This is not the final version because Qingchun and I still have two more days to work on it.
