Happy Home Education

Free GCSE/iGCSE Biology Unit 1 assessment: 20 questions with mark scheme, covering cell biology, microscopy, bacteria, viruses & stem cells (Weeks 1–6).

Week 6 of our GCSE/iGCSE Biology course: how one genome builds every cell type in your body. Covers cell differentiation, gene expression & stem cells.

Bacteria, Viruses, and the Question of What Counts as Alive The Big Question This Week "If something can infect you, reproduce, and even evolve, but isn't made of cells and can't survive on its own, is it actually alive?"

What Is Every Living Thing Actually Made Of? The Big Question This Week "If you had to build a living thing from scratch using only chemistry, where would you start?" Write this in your learning journal as a title before you begin. Don't look anything up yet, just think. You already made a guess about this at the end of Week 2. Go back and read what you wrote. Does it still feel right? Before You Begin — Predict! Write down whether you think these are true or false, and why:

"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.

A free, complete two-year iGCSE Biology course written for real home educating families. Year One covers the full content through videos, experiments, scientist stories and journal prompts. Year Two builds exam confidence through practice questions and technique — all at your own pace, however your family needs it.

Week 1 of our home education iGCSE biology curriculum. The scientific method, hypothesis vs theory, controlled experiments, and the scientists who changed everything.

Discover the exciting and violent story of how Earth's atmosphere was formed.

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
