Engineering, 4–6 years — 20 topics · MyLeoNes™ Kuks
20 engineering topics written for 4–6 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.

Plan, build, test, improve
Engineering starts with a need: make something that works. We can make a plan, build it, try it, and change it when the result is not right.
A wide base makes things steadier
Objects are less likely to tip when their weight is supported over a wide area. This helps us understand why towers, tables, and some toys need a firm, well-spread base.
Materials behave differently
Wood, paper, metal, plastic, and fabric each have useful qualities. Choosing a material means thinking about what an object must do, not just what it looks like.
Wheels help things roll
A wheel turns around a centre, letting an object move along the ground with less scraping. This simple idea appears in toys, trolleys, bicycles, and many other things that need to travel.
Levers help us move heavy things
A small push in the right place can move something much heavier. A lever helps by turning our push into movement around a steady point.
Ramps make lifting gentler
A ramp lets an object go up gradually instead of straight up. You use a longer path, but usually need less pushing at each moment.
Triangles strengthen frames
A square frame can wobble, but a triangle keeps its three corners at fixed distances. Builders use this shape when a frame must hold its form.
Pulleys help lift and guide
A rope around a grooved wheel can change the direction of a pull. With the right arrangement, several rope sections can also share the load.
Connecting parts
Engineers choose ways to hold separate parts together so an object can stay in one piece and do its job.
Hinges let things turn
A hinge joins parts while allowing one part to turn around a fixed line.
Roofs guide rain away
A sloping roof gives rainwater a path away from the inside of a shelter.
Sieves let some things through
A sieve or filter uses holes or a barrier to let smaller or wanted things through while holding back others.
Gears change turning
Gears are toothed wheels that pass turning from one part to another. They can make a turn faster, slower or go in the opposite direction.
Springs store a push
A spring can be squashed or stretched and then push back. This lets a thing store movement for a short time and release it later.
Measure before making
Measuring tells us how long, wide or tall something is. Engineers measure before cutting or joining parts, so the pieces fit instead of relying on a guess.
Waterproofing keeps water out
Waterproofing uses a material, cover or seal to stop water entering. It protects things that must stay dry and helps people stay dry too.
Bridges cross gaps
A bridge gives people and things a safe path across a gap, such as a river or a road.
Counterweights help balance
A counterweight is a weight placed on the other side to make lifting or holding something easier.
Signals tell machines what to do
A button, light or sound can carry a simple message that makes a machine start, stop or change.
Guards protect people
A guard keeps fingers, hands or people away from a moving or hot part while the useful work continues.
