Default want to create a solar powered rotating display for class

I am new to this, so if I say something that doesn't make sense,
please bear with me. For my class I am teaching, I want to create a
rotating HORIZONTAL CD that is slowly turned by a motor (from a dollar
store toy). I was thinking about buying a bag of broken Solar panels
from here :

but if someone knows a better place to buy at a cheaper price or
better material, please let me know.

1) I wanted to buy the motor (which need 2 double AA batteries to run)
and have it spin a horizontal CD on top, like a rotating display and
connect it to the solar panels from the grab bag - but I am unsure if
this is even feasible with the material or even the motor.

2) If there is some instructions on how to do this, that would be
great or if someone could point me in the right direction, I would
appreciate it.

You've got several problems.
How much current does the motor need to start/run?
Measure it.
Toy motors are probably not designed to run on low current.
You have no idea what solar cells you're getting.
Solar cells are rated for a LOT of light. Unless you're
running it outside in direct sunlight, you won't get
nearly the current you expect.

Go buy a packaged solar panel. You can get one designed to
keep your car battery charged for about $20 at a auto parts store
or harbor freight online. It'll be rugged and save you much
hassle. And it'll have a specification, so you can determine
if it will run your motor before you buy it. And you get tired
of watching your gizmo run, you'll still have a solar panel
that can keep your RV battery charged.
