HOW A SPIDER'S WEB FORMS

            A spider web looks delicate but it is very strong. I can hold 4000 times a spider's weight. But how does it form?
            First, the spider spins a thread of silk. The thread gets blown over to branch by the wind. Then she makes another to threads and make a Y shape. Next she makes more threads and they look like spokes off a wheel. Then the spider goes in a spiral, out and back in, sits in the middle and waits for food. This is how a web is formed.

The new vocabularies:

Web            : (noun) net of fine thread made by a spider.
Delicate       : (adj) needing careful handling or treatment.
Spin             : (verb) turn round and round quickly.
Thread         : (noun) cotton,silk, wool, etc used in sewing.
             ( verb) put a thread through a narrow opening or hole.
