Year 6 Science homework exploring bacterial, viral, and fungal structures alongside Alexander Fleming's discovery of penicillin to build scientific literacy.
Independent learning tasks that consolidate classroom learning or prepare students for future topics, accessible to all students regardless of home resources.
Subject: Science | Year: 6
Estimated Time: 30–40 Minutes Name: _________________________ Class/Set: ____________ Due Date: ____________
Why are we doing this? To consolidate your understanding of how microorganisms can be both beneficial and harmful to the human body and the wider environment.
Categorise: In your exercise book, create a small table to list the three primary types of microorganisms we have studied: Bacteria, Viruses, and Fungi.
Examine: Research or recall one 'helpful' microorganism and one 'harmful' microorganism. For each one, write its name and describe exactly what it does (e.g., how it helps us produce food or how it causes a specific illness).
Draft: Write a formal paragraph (5–8 sentences) explaining the importance of hygiene in controlling the spread of harmful microbes. Use at least three of these scientific keywords: transmission, organism, reproduce, sanitation, or microscopic.
Illustrate: Draw a scientific diagram of a fungal microorganism, such as a mould or yeast cell, and label at least one part of its structure.
☐ I have correctly named the three main types of microorganisms.
☐ I have provided one example of a helpful microbe and one harmful microbe.
☐ I have written a paragraph using Tier 2 scientific vocabulary.
☐ I have included a labeled diagram of a fungus.
⚠ TEACHER’S GUIDANCE & MARK SCHEME (DO NOT PRINT FOR STUDENTS)
Task 1 (Categorise): Students must list Bacteria, Viruses, and Fungi. (Protists/Protozoa may be mentioned by high-attaining students but are not statutory at KS2).
Task 2 (Examine):
Task 3 (Draft): A high-quality response (WAGOLL) should state: "Maintaining high standards of sanitation is vital to prevent the transmission of harmful bacteria. Because these organisms are microscopic, they can spread easily via touch or coughs. By washing our hands, we stop them from finding a host to reproduce in, thereby keeping us healthy."
Task 4 (Illustrate): Diagram of yeast (ovoid shape with vacuole/nucleus) or bread mould (hyphae/sporangium).
Challenge Answer: Fleming's discovery allowed doctors to treat bacterial infections that were previously fatal. It led to the mass production of antibiotics which have saved millions of lives.
"All Microbes are Germs": Many students believe all microorganisms cause disease. Emphasise that life on Earth would be impossible without helpful bacteria and fungi (decomposition, oxygen production, digestion).
"Viruses are Bacteria": Students often conflate the two. Remind them that antibiotics only kill bacteria, not viruses.
Size Perception: Students often struggle with the scale. Use the analogy that if a human cell were the size of a football stadium, a bacterium would be the size of a football.
The Great Decay: "If all decomposers (fungi and bacteria) suddenly disappeared tomorrow, what would happen to our local park or woods within a month?"
The Survivalists: "Microorganisms can survive in boiling volcanic vents and freezing arctic ice. What 'superpowers' do they have that humans do not?"
Mitigating the risk of surface-level comprehension regarding microscopic life requires a structured approach to independent retrieval. The inclusion of the 'Great Decay' discussion starter forces pupils to synthesise the ecological role of decomposers beyond simple pathogen identification. By utilising a dual-coded approach with the fungal diagram task, the worksheet reduces intrinsic load while anchoring abstract cellular structures in concrete visual representations. The homework provides a robust home learning task that ensures Year 6 learners transition from basic observation to the complex application of scientific vocabulary, securing the foundational knowledge required for Key Stage 3 biological systems.
