Matter

Matter in IB MYP Grade 3 Chemistry

In IB MYP Grade 3 Chemistry, Matter gives intermediate learners (ages 13–14) the chance to practise describing properties of materials, investigating states of matter and changes and understanding particle theory of matter.

MYP Chemistry is assessed against four criteria (A: knowing and understanding, B: inquiring and designing, C: processing and evaluating and D: reflecting on the impacts of science). Regular practice with matter builds the knowledge and skills those criteria reward.

What learners practise

Describing properties of materials
Investigating states of matter and changes
Understanding particle theory of matter

For students

Work through the worksheets, practice questions and revision resources at your own pace. Check your answers, then redo anything that felt tricky and explain each answer in your own words.

For revision

Use these resources for homework, end-of-unit revision and catching up on anything missed in class.

For teachers

Use matter activities as a starter, homework or retrieval practice, and mix free and premium resources to differentiate.

Study tip

Sketch a quick diagram or flow chart for every process you study. Visual summaries are far easier to revise from than paragraphs.

Quick answers

Who is the Matter page for?

It is for IB MYP Grade 3 Chemistry learners, typically aged 13–14, and for the parents and teachers who support them.

Are matter resources free?

Many are. Each resource shows a clear Free or price label, so you can start with the free ones and add premium resources when you need more practice.

How should I use these resources?

Pick one resource, complete it without help first, then check and correct. Repeating this little and often is more effective than one long session.
