A flat circle of iron oxide-coated plastic enclosed in a hard plastic case is called a floppy disk. It was commonly used for data storage and file transfer in older computer systems before USB drives and cloud storage became prevalent.
Earth's plastic-like layer is called the lithosphere. It is the rigid outer layer of the Earth, consisting of the crust and the upper part of the mantle. It is broken into pieces called tectonic plates that float on the semi-fluid asthenosphere underneath.

The microscope you are referring to is likely a stereomicroscope, which is also known as a dissecting microscope. It is commonly used for viewing larger specimens at low magnifications with depth perception.
The piece of glass used to observe specimens under a microscope is called a slide. Sometimes a thin piece of glass is used to cover the specimen. This is called a coverslip. Coverslips and slides can be made of glass, quartz or plastic, as long as these items are totally transparent and do not introduce any distortion. Sometimes the material may be tinted in order to add contrast, although this is usually done with dye.
