I think that this video is quite helpful because not only does it tell us what a physical and chemical change is, it also lists examples of why the change is a physical/chemical change. For example, he said that if it is a chemical change, it will produce gas.

I think that this video is very useful to help me identify the chemical and physical changes' indicators as this video not only explained it but showed why with examples and I have learned quite a lot.

I think that this video is trying to give out information. Although it doesn't explain chemical and physical changes that well, it gave examples on what they were. I think this video really improved my learning.

This video is boring, but useful.
