Common questions

What do 4th Grade students learn about biological sciences?

Living things, their features, life cycles, bodies and environments. At 4th Grade, our resources focus on: describing what a habitat provides; reading and building food chains; classifying producers and consumers; explaining how living things depend on each other.

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.
