Do for the activity. Make for building something.
We use do to talk about the activity, but do not say what it is.
- What are you doing this evening?
- What can we do?
We use do to talk about work.
- Who does your cleaning?
- I don’t want to do any work today.
We use make to talk about building or creating something.
- The company I work for makes children’s toys.
- I made some fresh coffee and sat down with my book.
Compare:
- I must make Gary’s cake. I’ll do it now.
(Make for the creation and do for the activity.)
