Human Systems in IB PYP Grade 4 Science
This page collects Human Systems resources for IB PYP Grade 4 Science. Learners at this confident stage work on naming the main organs and body systems, understanding how the heart, lungs and digestive system work and seeing how systems work together.
PYP learning is inquiry-based: children explore ideas through questions, play and real-life examples, so worksheets and games here are designed to be short, clear and encouraging.
What learners practise
- Naming the main organs and body systems
- Understanding how the heart, lungs and digestive system work

For students
Work through the worksheets and interactive activities at your own pace. Check your answers, then redo anything that felt tricky and explain each answer in your own words.
For parents
Sit with your child for the first few questions and ask “how do you know?”. Praise effort and keep sessions short.
For teachers
Use human systems activities as a starter, homework or retrieval practice, and mix free and premium resources to differentiate.
Link every fact to an everyday example. Ideas you can connect to real life are much easier to remember and apply.
