What is the movie were big scorpions pop out of ground and there character with wooden skin glowing eyes I remember name?

The movie you are thinking of is probably Tremors (1990). The film is about giant worm-like creatures called Graboids that live underground and hunt by sensing vibrations. The characters in the movie use various methods to kill the Graboids, including guns, explosives, and even a giant fan. The main character, Val McKee, is played by Kevin Bacon.
