"If someone shrank you down to the size of a single cell, what do you think you'd actually see?"

What makes something alive? Week 2 of our iGCSE Biology course explores the seven characteristics of life, the twelve levels of organisation from atom to biosphere, and the famous Miller-Urey experiment that asked whether life could arise from chemistry alone. Includes video links, journal prompts and a 10-question practice set.

Year Two builds exam confidence through practice questions and technique — all at your own pace, however your family needs it.

This week, we go deeper into what cells do. You’ll find out how your body knows what to build, when to grow, and how to repair itself, and it’s all hidden inside your DNA.

This week, you will explore how scientists can study cells in detail using microscopes. You’ll discover the differences between light microscopes, which use lenses and visible light, and electron microscopes, which use beams of electrons to reveal far greater detail. You will also learn how to use the magnification formula to calculate the actual size of tiny structures, and why improvements in microscope technology have been so important for advancing our understanding of bi
