An excavator is like a big, strong robot that helps us dig in the dirt!
It has a huge bucket on the front, kind of like a big spoon, that can scoop up lots of dirt. When we need to build things like houses or roads, we use the excavator to dig big holes. This helps us make a solid place for us to put bricks and concrete.
Sometimes, it also digs holes for pipes. These pipes are super important because they carry water and gas into our homes so we can take baths, drink water, and cook food.
So, whenever you see a big machine with a bucket moving dirt, it’s probably an excavator helping to build something!
