Core Skills Analysis
Science
- Observed and identified coastal organisms and remains, including sea snails, shells, crabs, cuttlefish skeletons and sea urchins.
- Compared living animals, shells and skeletons, supporting understanding of biological structures and evidence of life.
- Observed erosion when wind removed the sand mandala and connected the change to a natural process.
- Explored wave patterns and discussed how rip currents work, building understanding of moving water and coastal hazards.
Geography
- Investigated how wind and waves change a coastal environment over time.
- Used direct observation to notice that sand artwork was altered by wind, providing evidence of coastal processes.
- Discussed rips as features of the beach environment and considered how water moves through coastal areas.
- Developed place-based understanding by learning from the local beach rather than only from diagrams or text.
Mathematics
- Created mandala patterns, using repetition, symmetry and spatial arrangement in a practical setting.
- Observed recurring wave patterns and began noticing regularity, direction and variation in natural forms.
- Compared the shapes and structures of shells, sea urchins and cuttlefish skeletons through visual exploration.
The Arts
- Designed temporary sand mandalas using lines, shapes, patterns and balanced composition.
- Experienced how an artwork can change through interaction with wind and the natural environment.
- Connected creative expression with observation of coastal textures, forms and natural materials.
English
- Built topic vocabulary connected with beaches, erosion, waves, rips, shells and marine life.
- Practised explaining observations and processes, including how the mandala was changed and how rips work.
- Developed opportunities for sequencing and recounting events from the beach investigation.
Health and Physical Education
- Learned that rips are a beach hazard and discussed how they work, supporting water-safety awareness.
- Applied attention and observation skills while exploring rocks, marine life and changing beach conditions.
- Participated in active outdoor learning in a natural environment.
Tips
Tips: Extend the experience by making a labelled beach-observation journal with drawings, new vocabulary and questions. Compare a photograph of the mandala before and after the wind, then discuss which evidence shows erosion and what other forces might change sand. Create a tray model with sand and water to observe miniature wave movement, while making clear that classroom models do not reproduce real beach conditions. Finish with a safety poster or short role-play explaining what a rip looks like from shore and why swimmers should follow lifeguard advice.
