Photosynthesis AQA GCSE Biology – 3 Lessons + Required Practical
Photosynthesis lessons for AQA GCSE Biology 4.4: three 60-minute lessons with the light-intensity required practical, worksheets and an assessment.
Includes the Pondweed Lab: an offline interactive where students move the lamp, count the bubbles, see their means plotted against distance and 1/d², and name the limiting factor. It works on a whiteboard, laptop or phone. If the practical cannot run (or for a cover lesson), the simulation or backup data keep the analysis going; they do not replace the hands-on required practical your students should still carry out.
Photosynthesis is the endothermic reaction in which plants and algae use light energy to make glucose and oxygen from carbon dioxide and water. These lessons cover AQA GCSE Biology 4.4.1 for separate and combined science.
What’s included
3 lessons (60 min each): 1) the reaction and the leaf, 2) limiting factors with the inverse square law and greenhouse economics (Higher), 3) the light-intensity required practical with data analysis (groups test 3 distances and pool class results)
6 editable PowerPoint decks: Teacher slides (answers and speaker notes) and Student slides
9 editable Word worksheets: Support, Core and Stretch for each lesson
Required practical write-up frame and a backup results data sheet
Exam-style assessment (48 marks Higher, 36 Foundation) with mark scheme, plus a full answer key
Card pack for Limiting Factor Stand-Up and Pathway Relay
Teacher guide (timings, technician checklist, safety notes, misconceptions), START HERE page and 22 print-ready PDFs
Accuracy: the word equation, symbols and practical numbers are checked against the AQA specification; the balanced symbol equation (6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂) is atom-checked and every answer is script-checked.
