Looking closely at materials
Chemistry · Key Stage 1 · The School
Detail hiding in plain sight
Look at a piece of wood from across the room. It looks smooth and plain. Now look through a magnifier. Thin lines run along it. This is called the grain. The wood was hiding detail the whole time.
Fabric is really a grid
A jumper looks like one soft piece. Through a magnifier it is not. It is hundreds of thin threads, woven over and under each other. Pull one thread and you can see the whole grid move. Fabric is a pattern, not a single material.
Salt and sugar look the same, until
Salt and sugar both look like tiny white piles. To the naked eye they seem identical. Under a magnifier, salt crystals are small cubes. Sugar crystals are longer, with pointed ends. Close looking finds a difference the eye alone cannot.
Looking at three materials in a row
Line up a cotton sock, a wooden ruler and a sheet of paper. To the eye, they just look like three different colours. Through a magnifier, the sock shows woven threads. The ruler shows a grain of thin lines. The paper shows a mesh of tangled fibres, packed flat. Three materials, three completely different hidden patterns.
Recording what you saw
Draw what the magnifier actually showed you, not what you expected. Label the parts, like "grain" or "threads". Write down which material you looked at. A drawing with no label is hard to use again later. A labelled drawing is real evidence.
