Biology, 7–10 years — 20 topics · MyLeoNes™ Kuks
20 biology 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.

What living things need
Living things are active: they need materials and energy to grow, repair themselves and stay alive.
How plants make food
Green leaves use light to make sugar from water and carbon dioxide. This is how a plant gets much of its food.
Food chains
A food chain shows who gets energy from whom. It starts with a plant and follows feeding links between living things.
Habitats and what they provide
A habitat is a living thing’s local home. It supplies the conditions and resources that help it survive.
Life cycles
Living things change in stages, from beginning to adult and sometimes back to a new beginning.
Bones and muscles work together
Bones support and protect the body, while muscles pull on them to make movement possible.
Animals can be grouped by body plans
A backbone is one useful clue for sorting animals, but animals without backbones can have other strong body structures.
Adaptations help living things survive
Some inherited features suit an organism’s surroundings and make survival or reproduction more likely.
Cells: the tiny building blocks of living things
Every plant and animal is made of cells. Cells are too small to see without a microscope, but together they make bodies grow, work and repair themselves.
Digestion turns food into usable materials
Food cannot help the body while it is still in large pieces. Digestion breaks it into smaller substances that can pass into the blood and be used for energy, growth and repair.
Breathing brings oxygen to the body
When we breathe in, oxygen enters the lungs and then the blood. When we breathe out, carbon dioxide leaves. This exchange helps cells release energy from food.
Microbes: tiny living things around us
Microbes are living things too small to see without special equipment. Some can make us ill, but many are harmless or useful, helping make food, recycle materials and live in our bodies.
Pollination helps plants make seeds
Pollen must travel from one flower part to another before many plants can make seeds. Wind and animals, especially insects, often carry it.
Our senses send information to the brain
Eyes, ears, nose, tongue, and skin detect changes around us. The brain helps us understand those signals and choose a response.
Blood transports materials around the body
Blood moves through vessels, carrying useful materials to cells and taking some waste away. The heart keeps this transport moving around the body.
Inherited traits explain family resemblances
Living things receive instructions from their parents, so relatives may share features. Small differences still appear, which is why family members are not identical.
Seed dispersal
Seeds need ways to travel away from the parent plant.
Decomposers recycle dead matter
Fungi, worms and other decomposers return materials to the soil.
Ecosystems are connected places
An ecosystem includes living things, their surroundings and the links between them.
How animals produce young
Animals produce young in different ways, helping their species continue.
