Year 9 Material World
Matter – in all its varied forms – and the way it can change both physically and chemically is at the heart of the ‘Chemical World’. In this course you’ll work through four main sections:
- Matter and physical change – we’ll explore what matter is and what kind of physical changes it can undergo.
- Chemical changes – in this second section we’ll move on from physical changes to look at chemical changes.
- Three common gases – in this section we’ll look specifically at three very common gases: hydrogen, carbon dioxide and oxygen. You’ll learn more about their structure and properties, how they’re produced and used, and how you can test for their presence.
- Chemistry in everyday life – to finish this introduction to the material world we’ll focus on several specific applications of chemistry in ways that affect our everyday lives: crude oil and the petrochemical industry, polymers and plastics.
This course will give you a good grounding in the basic knowledge, language and skills you need to take forward to the Material World section of Year 10 Sciences, and then on to Years 11–13 when it’s called Chemistry.
How you’ll learn
People learn in different ways. Here are some of the ways you can learn and interact with the materials in this online course.
Self-paced learning – This online course is set up so you can learn at your own pace. So, although there are ‘suggested’ times for each page, they’re just a guideline. Plan your learning to suit you.
Diagrams, videos and interactions – Some people prefer to learn by reading, some by watching and listening, and some by doing. We’ve used diagrams, videos and interactions alongside the text, so that there’s something for everyone!
Practice activities – Throughout this course there are lots of short activities. These activities are for you to check your own understanding, not for someone to mark them. These activities give you a great chance to practise what you’ve learned and compare your answer with the model feedback without being assessed.
Glossary – We’ll be using some technical words and phrases in this course. To help you grow your vocab around the topics, the course includes an online glossary. When you see a word or phrase underlined in the text, move your cursor over it and a definition will pop up – easy as! You can also choose to print a copy of the full glossary.
Discussions – Sharing with others can also be a great way to learn. Talk with your classmates and teacher at school about the ideas you come across in this online course. Even chat to your whānau at the dinner table about the things you’re learning – if you can explain the ideas to others, you can really be confident in your own understanding.
