Acids and Bases

Acids and Bases in IB MYP Grade 2 Chemistry

Acids and Bases is part of IB MYP Grade 2 Chemistry. At this developing stage (ages 12–13), learners work on exploring sour and everyday substances, investigating acids and bases simply and understanding the pH scale.

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

Exploring sour and everyday substances
Investigating acids and bases simply
Understanding the pH scale

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 2 Chemistry learners, typically aged 12–13, 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.
