Natural Sciences: a branch of Science that deals with understanding nature.
The five major branches of Natural sciences:
Astronomy, Biology, Chemistry, Earth Science and Physics!

I believe physics to be the most basic natural science (doesn't mean it's easy) and that other natural sciences build upon it.
Natural sciences are great!

Chemistry teacher: That's the physics of it!
