Acids and Bases

Acids and Bases in IB MYP Grade 3 Chemistry

This page collects Acids and Bases resources for IB MYP Grade 3 Chemistry. Learners at this intermediate stage work on investigating acids and bases simply, understanding the pH scale and analysing acid-base reactions.

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 acids and bases builds the knowledge and skills those criteria reward.

What learners practise

Investigating acids and bases simply
Understanding the pH scale
Analysing acid-base reactions

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

Study tip

Read each question for the command word (describe, explain, compare) before you start. It tells you how much detail is expected.

Quick answers

Who is the Acids and Bases 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 acids and bases 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.
