How to teach Biology at home: a guide for home educators

Biology can be one of the most naturally engaging subjects to study at home, because it can be seen, and felt, in the world around us - how our bodies work, why species evolve, how ecosystems balance themselves - in ways that make abstract concepts feel grounded and real.

Biology is also one of the most content-heavy GCSE and A-level subjects, which means that when you reach that point, approach and structure can matter as much as enthusiasm.

This guide covers how to teach Biology at home from Key Stage 3 (KS3) through GCSEs and on to A-level.

What makes Biology different from the other sciences

Biology sits alongside Chemistry and Physics in the science curriculum, but it has a distinct character.

Where Physics leans heavily on mathematical reasoning and Chemistry on understanding reactions and bonding, Biology requires strong memory and retrieval skills, a grasp of specific scientific vocabulary, and the ability to apply conceptual understanding to unfamiliar contexts.

This matters for how you approach teaching it at home. Mnemonics, retrieval practice, and regular low-stakes testing are more effective for Biology than simply sitting and passively reading notes. Building in regular recall exercises, where a student tries to reproduce what they know from memory before checking their notes, is one of the approaches that’s widely  supported by research.

Teaching Key Stage 3 (KS3) Biology (Years 7, 8 and 9, ages 11 to 14)

At KS3, Biology is taught as part of an integrated ‘Science’ curriculum rather than as a standalone subject. 

During KS3 Science, students cover cells, reproduction, health and disease, photosynthesis and respiration, ecosystems, and genetics in broad introductory terms, laying the foundations that GCSE Biology will build on.

Year 7, Year 8 and Year 9 are the ideal time to create and develop skills which will be useful later down the line. To give just one example, because Biology is a heavily visual subject at GCSE - cell structures, organ systems, the carbon cycle, food webs - it helps to get children used to drawing and labelling diagrams. 

To help you get started here are some free resources:

• BBC Bitesize KS3 Biology - free topic-by-topic resources covering a wide-variety of KS3 Biology content, including video explanations and interactive quizzes

• Oak National Academy KS3 Science - aligned to the KS3 Science curriculum more broadly, Oak National Academy covers Biology content in their free slides, worksheets, and assessment materials

• Médecins Sans Frontières (MSF) teaching resources - curriculum-aligned KS3 Biology resources (plus GCSE and A-level), covering infectious diseases, malnutrition, parasitic diseases, and vaccination - all developed by qualified teachers and grounded in real-world medical contexts

For home educated students at KS3, we offer the full Science curriculum across Year 7, Year 8 and Year 9. Students receive two live lessons per week, delivered by our experienced, expert teachers - plus bespoke workbooks, practice questions, 24/7 study support and access to a mentor.  

Teaching GCSE Biology at home

GCSE Biology is one of the three Triple Science subjects, alongside Chemistry and Physics.

AQA GCSE Biology is built around a core understanding of biological principles, including the structure and functioning of cells and how they divide by mitosis and meiosis, the role of variation and fertilisation, and the two essential reactions for life on Earth - photosynthesis and respiration.

The full specification is divided into seven topic areas assessed across two papers:

• Paper 1 - Cell Biology, Organisation, Infection and Response, and Bioenergetics

• Paper 2 - Homeostasis and Response, Inheritance, Variation and Evolution, and Ecology

Practical skills: what home educated students need to know

AQA GCSE Biology includes 10 practical skills. Unlike A-level, there is no separate practical endorsement at GCSE - the practicals feed into questions on the written papers rather than being assessed independently

The required practicals are clearly laid out in the specification and are deliberately open in their design, so students can develop and demonstrate the relevant skills in ways that suit their context. Around 15% of marks across both papers assess practical skills and working scientifically.

To help home educated students, we cover each practical skill in a dedicated live, online lesson, where students are taken through an example method before planning an experiment and working through related practice questions.  

Studying GCSE Biology online

With MyEdSpace, students cover the full GCSE AQA Biology curriculum with our specialist Biology teachers.

Joe Wolfenshon (@JoeDoesBiology) - a former examiner - builds on what students have covered in Key Stage 3 through Year 10, before Emma Williams (@EmmaDoesBiology) guides students all the way through Year 11 and in to their exams, with heaps of exam technique and practice included, to ensure no marks are left on the table. Daytime timetables are available specifically for home educated students.

The results our students then go on to achieve in exams speak for themselves. For example, in 2025, well over half of our students achieved GCSE grade 7 or above (56%), compared to under 25% nationally (22%). And, if that wasn’t impressive enough, three times more MyEdSpace students achieved GCSE grade 9 than the national average.

Teaching A-level Biology at home

A-level Biology is a significant step up from GCSE in both content volume and the depth of analysis required. It is also one of the most valued A-levels for university admissions in medicine, veterinary science, biological sciences, psychology, and healthcare. 

A-level Biology includes a separate practical endorsement (known as CPAC - Common Practical Assessment Criteria) which is assessed by teachers through direct observation of practical skills during the course. Unlike at GCSE level, the assessment of practical skills is a compulsory requirement at A-level - and should be taken into account when thinking about studying A-level Biology at home. 

The 12 required practicals for AQA cover: enzyme rate, root-tip mitosis, water potential, membrane permeability, dissection, aseptic technique, leaf-pigment chromatography, dehydrogenase activity, respiration in yeast, animal responses, glucose calibration by colorimetry, and the effect of an environmental factor on species distribution - other exam boards may vary. Practical skills account for around 15% of the written paper marks on offer.

As with GCSE Biology, to help prepare home educated students, each practical skill is covered in detail in a dedicated live, online lesson. Students are guided through an example method, planning an experiment and working through related practice questions.  

Studying A-level Biology at home

With MyEdSpace, students cover the full OCR and AQA A-level Biology curriculums with our specialist Biology teachers.

In Year 12, Joe Wolfensohn (OCR) and Emma Williams (AQA) build on what students have covered at GCSE, before Laura (@LauraDoesBiology) and Joe take Year 13 students all the way through to their exams, with heaps of exam technique and practice included.

The results our students then go on to achieve in exams speak for themselves. For example, in 2025, almost twice as many of our A-level Biology students achieved A or A* (45%), compared to non-MyEdSpace students (28%). Meanwhile, almost three-quarters of our A-level students achieved B or above (73%), nationally it was slightly over half (55%) and over half of our A-level students have been admitted into Russell Groups universities (56%) compared to only 27% across the UK
