• there are general laws or facts about our world - these are basic and more detailed rules about how things generally work.

• these facts also called laws were learned by studying the world systematically meaning very carefully in a well kept system

• these facts are also gained by experimentation and observation (which means trying to do different things to something to learn something about it and then writing down things the scientist saw)

• these laws or facts are kept in a systematic way another words they are organized or kept neatly.

• the laws or rules can be about physics or natural science which includes mathmatical sciences (the way you use numbers which are called operations)

It is really fun and educational to learn about new things in the world of science.   Sometimes you can just read about these laws but sometimes you can do experiments that help you understand how the laws of nature and physics work.
