Topic 2: Orders of Magnitude

Biology involves comparing structures and processes across a wide range of sizes. To make these comparisons easier, we use orders of magnitude — a way of expressing size differences using powers of ten.

This video explains how orders of magnitude help us compare these scales using powers of ten, making complex size differences easier to understand in a few, simple steps.
