Common questions

What do Year 3 students learn about chemical sciences?

Materials, their properties and how they change. At Year 3, our resources focus on: describing how materials change shape; observing what happens when materials are mixed with water; describing melting and freezing; sorting changes that can and cannot be undone.

Where should we start?

Start with the Level 1 or Level 2 worksheet, then move up a level. Finish with the topic test if there is one.

Are answers included?

Yes — every worksheet has an answer sheet. Maths answer sheets show the working; English tasks include model answers or success criteria.

How to use these resources

  1. Read the short explanation together before starting the questions.
  2. Where a worksheet suggests a simple experiment at home, try it: seeing beats reading.
  3. Ask "How do you know?" so answers are backed by evidence.
  4. Use the answer sheet to talk about why an answer is right, not just whether it is.
