Science: The Complete Guide for Ages 9–11

Everything your child needs for KS2 science — 16 short lessons across biology, chemistry and physics, from classifying living things to Earth and space. Each lesson takes about 3 minutes, uses clear diagrams, and comes with a printable cheat sheet.

🔬 Why science matters

Science teaches children to ask questions, test ideas and explain the world — and KS2 lays the groundwork for secondary biology, chemistry and physics.

🏫 What these lessons cover

The full KS2 programme: living things and the human body, plants and life cycles, materials and their changes, forces and magnets, light, sound, electricity, and Earth and space.

🎯 Myths corrected

Every lesson clears up a common misconception — plants don't eat soil, we don't see by light from our eyes, seasons come from tilt not distance, and food-chain arrows follow the energy.

The learning path

Work through the lessons in order — each one builds on the last.

1
Classifying Living Things
Vertebrates, invertebrates and the five animal groups, with classification keys.
2
Habitats and Adaptation
How animals and plants are adapted to their habitats.
3
Food Chains and Webs
Food chains explained: producers, consumers, and why arrows point to the eater to show energy flow.
4
The Skeleton and Muscles
How the skeleton supports and protects, and how muscle pairs pull on bones to move joints.
5
Digestion and Teeth
The digestive journey and the three types of teeth, plus what really causes tooth decay.
6
The Circulatory System
How the heart, blood and lungs work together to deliver oxygen around the body.
7
Plants and Photosynthesis
How plants make their own food by photosynthesis, plus the jobs of roots, leaves and flowers.
8
Life Cycles and Reproduction
Life cycles of insects, amphibians and mammals, metamorphosis, and how offspring inherit and vary.
9
States of Matter and the Water Cycle
Solid, liquid and gas, melting, evaporating and condensing, and how they drive the water cycle.
10
Materials and Their Properties
Material properties.
11
Reversible and Irreversible Changes
Which changes can be undone and which make a new material.
12
Forces and Magnets
Gravity, friction, air resistance and magnets explained.
13
Light and Shadows
How we see by reflected light, why light travels straight, and how shadows form and change size.
14
Sound
How sound is made by vibrations, travels through materials, and why pitch and volume differ.
15
Electricity and Circuits
How simple circuits work: cells, complete loops, switches and components.
16
Earth and Space
Day and night, the year, seasons and moon phases.

Frequently asked questions

What order should my child work through the science lessons?

Any order works, but the sequence here flows naturally: living things and the body first (SC1–SC8), then materials (SC9–SC11), then physics — forces, light, sound, electricity — and space (SC12–SC16).

What ages are these science lessons for?

Ages 9–11 (Years 5–6 in England), covering the upper KS2 science curriculum and useful for 11+ general-knowledge and science sections.

Are these lessons free?

Yes — all 16 lessons and printable cheat sheets are completely free. The MindBlaze app adds daily practice and rewards.

Are the lessons scientifically accurate?

Yes — each lesson is written to be KS2-accurate and deliberately corrects the misconceptions children (and adults) often hold, like 'the Sun moves round the Earth'.

Do the lessons cover 'working scientifically'?

Yes — fair testing, observing and explaining are woven into the lessons, such as comparing materials with a fair test and explaining everyday observations.
