Hi everybody! My name is Xavier and I am studying Natural Sciences at the college Lionel-Groulx. This is a glossary to help you to learn some technical aspects of the field of study called Natural Sciences. Indeed, the glossary targets teenagers that want to adventure themselves in the field of the Natural Sciences. All of the words in this glossary can help you to make a good start in sciences. Take a look at them to understand sciences a little better!
