Science Glossary

Hi everyone! My name is Lana, and I'm a student at College Montmorency. I'm currently in my third session of the Natural Science program. I made this glossary for students who are studying science or want to learn more about science vocabulary. My glossary has 20 terms from biology, chemistry, physics, and math. It can hep students understand words they might not know in their classes or during experiments. For each word, I included the part of speech, a simple definition, an example, voice audio to hear the word, and sometimes an image to help understands it. To choose my words, I picked terms that I often see in my science classes and that I think are useful to know. I used reliable sources on the internet, like Google, to find and check the definitions. I hope my glossary helps you learn some new words and understand science better. Take a look at the terms and see how many you already know!
