Natural Sciences Glossary

20 Natural Sciences terms

Hi, I have been studying in Natural Sciences for 2 years now and I have decided to create a glossary to help new student in my program. Natural Sciences is a program where students learn biology, chemistry, and physical. The course focuses on theory and on laboratories so the students can develop practice skill. Graduated can applique at university in big programme like medicine and biotechnology. In too years of study, students learn many new words and sometimes it can be difficult to remember all of them. For this reason, I have decided to create this glossary. It contains 20 words with their definition, their pronunciation, their part of speech and a translation of the word in French all of the sources are also mentioned. Good reading, I hope it will help you!
