Stairs

Stairs are an easy way to get from one level of a building to another. They usually consist of multiple steps with a railing on one side. You can walk up the steps to go up, or down the steps to go down. When you go up, each step is like a little hill that you have to climb. When you go down each step feels like a slide. It's a lot easier to go down than up, but remember to take your time and be careful!
