Science, 7–10 years — 20 topics · MyLeoNes™ Kuks
20 science topics written for 7–10 years — not a older text simplified. In teaching order, each a deck of five cards: the idea, why it exists, a worked example, the common trap and where you meet it.

Solids, liquids and gases
Matter can look and behave differently depending on how its tiny particles are arranged and moving. This helps explain why ice, water and steam are three forms of the same substance.
Forces change motion
A push or a pull can start, stop, speed up, slow down or turn an object. Thinking about forces helps explain everyday motion instead of treating it as something that simply happens.
The water cycle
Water travels between the ground, air, rivers, lakes and seas. Sunlight and cooling keep moving it through evaporation, condensation and precipitation.
Food chains
Living things depend on one another for food and energy. A food chain shows one path through an ecosystem, from a plant to animals that eat it and then to other animals.
Light and shadows
Light usually travels in straight lines. When an object blocks it, a shadow appears, and its shape and size can change.
Simple electrical circuits
Electric current can travel around a complete path. A battery pushes charge through wires and a component, such as a bulb, can use the energy.
How plants make food
Green plants use light energy to make sugar from water and carbon dioxide. This process, called photosynthesis, also releases oxygen into the air.
Why day and night happen
Earth spins like a slowly turning ball. The side facing the Sun has day, while the side turned away has night.
Sound comes from vibrations
Sound begins when something vibrates and makes nearby material vibrate too.
Magnets and magnetic forces
Magnets can pull some materials without touching them, and their poles affect how they interact.
Why seasons happen
Seasons happen because Earth is tilted as it travels around the Sun, changing how sunlight reaches each place.
How our body digests food
Digestion breaks food into small useful parts that the body can absorb and use.
Why the Moon changes shape
The Moon does not really grow or shrink. We see different parts of its sunlit half as it travels around Earth.
How animals are suited to their habitats
An adaptation is a body feature or behaviour that helps an animal live where it lives. It is shaped over many generations, not chosen by one animal.
How germs spread and how to stop them
Some microscopic organisms can make us ill and can travel between people through hands, droplets, food or surfaces. Simple habits can break that journey.
How rocks change
Rocks are not permanent. Weathering, pressure, heat and melting can turn one kind of rock into another over very long periods.
How pollination helps plants make seeds
Flowers need pollen to make seeds, but the pollen must reach the right part of a flower. Bees, wind and other helpers can move it.
Why some objects float and others sink
Water pushes up on objects. Whether an object floats or sinks depends on how its mass is spread through its size, not simply on whether it feels heavy.
How the skeleton supports and protects the body
Bones form a strong framework inside the body. They support us, protect delicate organs and work with muscles and joints to make movement possible.
How fossils show what lived in the past
A fossil is preserved evidence of ancient life, such as a bone, shell, leaf or footprint. Fossils help us learn about living things and places from long before people kept records.
