DO and DOES

Hello again everyone,
I am now in library, searching for materials to be written in this blog. Next to me, three girls are busy discussing about their science project. Annoyingly, they keep on committing grammatical errors in their conversation. Thus, I decide to post a video about the differences between DO and DOES. Happy watching!

From the video, I hope everyone of you will now understand and know when and where to use DO and DOES properly.
