A simple and clear explanation for young children on why screws are used instead of nails in building and crafts.
Hi there! Let me tell you why people sometimes use screws instead of nails when they want to join two pieces of wood or other things together.
Nails are little pieces of metal that you hit with a hammer. They go straight into the wood and hold it there. But sometimes nails can become loose if the wood moves or shakes a lot.
Screws are special because they have twists called threads, kind of like a twisty slide. When you turn a screw with a screwdriver, it digs in tightly and holds the wood pieces together really well. Screws don’t come out easily, and they keep things strong even if they move.
So, we use screws when we want something to stay extra strong and not wiggle loose. Nails are quicker to put in but screws keep things together better for a longer time.
Doesn’t that make sense? Screws help hold things tightly, while nails are faster but not always as strong.
