Traditional Coding in Nature

A honeybee dances in a figure-eight to tell her sisters exactly where the flowers are. A spider spins the same web shape every single time, without a teacher. Both animals are following a set of steps, in order, every time — and that is exactly what a computer program does too! Today we look for hidden 'code' all around us in nature.

- What a pattern is, and how to spot one - What a sequence is (steps done in order) - How animals and plants follow step-by-step patterns - How to write your own simple step-by-step pattern

Look at a sunflower's middle — the seeds swirl in curved lines that repeat over and over. Look at a honeycomb — every single cell is the same six-sided shape, lined up in neat rows. These repeating shapes are called patterns. A pattern is something that happens the same way, again and again, so you can guess what comes next.

A caterpillar does not become a butterfly all at once. It follows a sequence: first it hatches, then it eats and grows, then it forms a chrysalis, then it changes inside, then it comes out with wings. If you did the steps out of order — wings before the chrysalis — it would not work! Computers work the same way: a set of steps, done in the right order, is called a sequence, and it is the most basic building block of coding.

Pinecones and pineapples both grow their scales in spiraling patterns that follow the same repeating number rule every time, no matter where in the world they grow. That is because the plant is following the same 'instructions' every single time it grows — just like a computer follows the same instructions every time it runs a program.
