Okay kiddo, do you know what rules are? They're like instructions that tell you what you can and can't do. Just like how your parents tell you to brush your teeth every day.
Well, imagine there were rules for the entire state of Pennsylvania! These rules are called the Pennsylvania Code. It has a really long list of rules that tell people what they can and can't do in different situations.
For example, the Pennsylvania Code might have rules on how fast cars can drive on the highways, how many hours someone can work, what kind of building materials can be used to build houses, and what kind of chemicals factories can put into the air and water.
Now, the Pennsylvania Code is made by a group of people called lawmakers, who are like grown-up versions of your teachers. They get together and talk about what rules are needed to keep everybody safe and happy.
The Pennsylvania Code is really important because it helps make sure everyone follows the rules and stays safe. But sometimes, the rules can change, just like how your parents might change their rules at home. So, people need to keep up to date with the Pennsylvania Code so they don't accidentally break any rules.
