In an iPhone 4s can it zoom in while while taking a picture or video?

Since no mobile has an optical zoom, any "zooming" will actually be cropping of the already tiny sensor on the mobile, whether it is made by Apple or other mobile maker.

It seems that your vision of what your video is to look like when you are finished shooting it, exceeds the abilities of your choice of camera.

Some more advanced video cameras can zoom when shooting scenes, but really, the real reason for having a zoom lens is so that you do not have to move the camera for each scene you are shooting.

The act of "zooming" during a take is the filmatic version of an exclamation point. How may of those can you stand in reading a whole book? You can view many videos that use NO zoom at all.

I suggest you ask your film professor about the various terms and use of technique to create a great story by using them sparingly as you shoot and later edit the video.

Using a mobile is no reason not to use established film making skills and techniques when producing a video.

If you knew more about how films and videos were made, you probably would not have depended upon a mobile for shooting your video script. For under $200, there are many tiny Full HD video cameras available with actual optical zoom lens.

Your knowledge about movie making is very important when you start picking the equipment you will need to complete the final product

Bottom line? You seem to have the passion necessary to produce brilliant videos, but have no understanding of the type equipment you need to produce them and no understanding of the fundamentals of shooting videos.

Only on the outer camera and in picture mode only, doesn't work with video

Phone cameras don't have optical zoom.

If you attempt to use some kind of digital zoom, it will look awful. Check your phone's user manual, it will tell you if it has digital zoom, and how to use it.
