How is a house built? Loggers cut down trees that are sent to a sawmill and made into boards. These boards are sent to builders who use them to build the floors, walls, and roof of the house. Electricians run wires for electricity and plumbers put in pipes for water. Then, the inside of the house is decorated and made ready for a family to live in it.
How are crayons made? Clear wax is melted in a factory. Once it's melted, color is added to it, it is poured into crayon-shaped molds, cooled, and wrapped in a paper label. Sorted into sets, the brightly colored crayons are boxed and sent in trucks to stores to be sold to you.
