Look around your room right now. Why is your desk made of hard, sturdy stuff instead of floppy paper towels?
Every object you touch is made of a specific substance called a material.
The Four Everyday Materials
Four of the most common materials around us are wood, paper, plastic, and fabric.

How can you tell these four materials apart when you are touching them?
Wood and Paper
Wood comes from trees and feels hard, stiff, and strong. We use it to build things that need to stay solid, like tables and doors.
Paper also comes from trees! Wood gets broken down into tiny plant fibers and pressed into thin, flat sheets you can fold and draw on.
What about your colorful toys and the soft clothes you wear to school?
Plastic and Fabric
Plastic is a human-made material that can be molded into almost any shape, from smooth toy bricks to waterproof water bottles.
Fabric is made from soft threads woven together. It bends easily, making it perfect for your shirts, curtains, and socks.
