The Spore Journey

Overview

Students investigate how fungi reproduce through spores, linking spore formation, dispersal and germination in a cause-and-effect sequence. They compare moulds, which produce spores directly, with mushrooms, which produce spores from visible fruiting structures, and use evidence to explain how spores support survival.

Learning intentions

Students will:

• explain how most fungi reproduce using spores
• compare spore production in moulds and mushrooms
• connect dispersal and germination with suitable environmental conditions
• use evidence and scientific vocabulary in collaborative discussion
• distinguish observations from reasonable inferences

Success criteria

• I can describe the journey from spore formation to a new fungus.
• I can explain one similarity and one difference between moulds and mushrooms.
• I can use evidence to explain why dispersal and germination help fungi survive.
• I can identify and correct a misconception about fungal reproduction.

Curriculum links

• Biological Science — reproduction: animals, plants and fungi reproduce in different ways, including by producing spores.
• Biological Science — fungi: most fungi reproduce sexually through fertilisation, fruiting bodies, spore formation, dispersal and germination.
• Biological Science — organism diversity: organisms have different reproductive strategies.
• Te Mātaiaho Science capabilities: asking questions, using evidence, explaining cause-and-effect, and communicating scientific ideas.

Lesson structure (80 minutes)

1. 0–7 min · Hook and prior thinking. Display a striking close-up image of mould and a mushroom cap using the opening image and hook question. Ask: “How could something so small begin a whole new fungus?” Students write an initial explanation, then share with a partner; teacher records ideas without confirming them.

2. 7–17 min · Teacher explanation. Use the fungal reproduction explanation slides to explain that most fungi reproduce by forming spores. Clarify that spores are reproductive cells, not seeds; they are produced in large numbers and can be dispersed by air, water, animals or contact. Explain that a spore may germinate when it reaches suitable conditions such as moisture, nutrients and an appropriate temperature. Show that moulds produce spores directly, while mushrooms are visible fruiting structures that produce and release spores. Emphasise that a visible mushroom is only part of the fungus. Students annotate the sequence on the spore journey investigation sheet and ask clarifying questions.

3. 17–32 min · Group round 1: sequence and cause. Place students in groups of five with roles: facilitator, evidence finder, recorder, questioner and reporter. Using the diagram and prompts on the spore journey investigation sheet, groups order the stages: spore formation, dispersal, landing, germination and growth of a new fungus. They must add a cause-and-effect sentence for each arrow. Groups discuss Questions 1–3 below and record evidence-based responses.

4. 32–47 min · Group round 2: moulds and mushrooms. Revisit the mould and mushroom comparison slides. Groups create a two-column comparison and discuss Questions 4–7. They identify which statements are observations and which are inferences, then prepare a 30-second report using either a mini-whiteboard comparison, a spoken explanation or a labelled flow diagram. Teacher circulates, checks vocabulary and challenges unsupported claims.

5. 47–62 min · Group round 3: survival problem-solving. Present the scenario on the survival challenge slide: “A fungus releases many spores, but most land on dry, exposed surfaces. Why might this still be a successful strategy?” Groups brainstorm at least three ideas, such as producing many spores to increase the chance that some reach suitable conditions; using wind, water or animals for dispersal; and remaining inactive until moisture and nutrients are available. They discuss Questions 8–10, choose their strongest explanation, and report using a cause → condition → outcome structure.

6. 62–72 min · Share, challenge and correct. Each group reports one comparison or survival explanation. After each report, another group gives one evidence-based “agree, add or challenge” response. Teacher addresses misconceptions: spores are not seeds; not every spore germinates; mushrooms do not represent the whole fungus; and mould does not appear from nowhere. Students improve one answer on their worksheet.

7. 72–80 min · Exit ticket and review. Students complete the final section of the spore journey investigation sheet independently: “Explain how a spore could become a new fungus, and include one difference between moulds and mushrooms.” Collect responses and ask students to rate their confidence from 1–5.

Discussion questions

1. What is a spore, and how is it different from a seed?
2. Why do fungi produce and release many spores?
3. What happens when a spore reaches suitable conditions?
4. What evidence suggests that mould reproduces using spores?
5. What is the visible mushroom structure used for?
6. Why might a mushroom release spores from a cap rather than keep them enclosed?
7. How are mould and mushroom reproduction similar and different?
8. Why might most dispersed spores fail to produce new fungi?
9. How could wind, water, animals or people help disperse spores?
10. Why does germination depend on conditions such as moisture, nutrients and temperature?

Resources

• the spore journey slide deck
• the spore journey investigation sheet
• Projector or interactive board
• Images of mould and mushrooms
• Mini-whiteboards or A3 paper
• Pens, pencils and highlighters
• Timer
• No live mould or open fungal samples

Assessment

• Listen for accurate use of spore, dispersal, germination, fruiting structure and reproduction during group discussion.
• Check sequence arrows, cause-and-effect statements and comparison explanations on the worksheet.
• Use the exit ticket to assess whether students can explain the complete spore journey and distinguish moulds from mushrooms.

Differentiation

• Support Year 7 learners with a word bank, a completed example arrow and sentence starters: “When…, therefore…” and “Both…, but…”.
• Challenge Year 8 learners to explain why producing many spores can compensate for low germination success and to evaluate which dispersal method is most effective in a given environment.
• Provide illustrated vocabulary, read questions aloud and allow oral recording or labelled diagrams for EAL learners and students who need literacy support.
• Pair students strategically, assign accessible roles and provide a partially completed sequence for students requiring additional structure.

Safe classroom practice: use photographs, diagrams or prepared digital images only. Do not collect, open, grow or handle live mould. Students wash hands after the lesson, avoid touching their faces, and report any allergy or respiratory concern to the teacher.
