Discovering Material Science Through Crafting and Polishing Aluminium Foil Balls / Activity Analysis

Core Skills Analysis

Science and Physical Development

• Learned about the properties of materials, such as the malleability of aluminium foil and how it can be compressed and shaped.
• Developed fine motor skills through the physical action of crumpling and compressing a large piece of foil into a solid ball.
• Observed the transformation of a flexible, flat object into a compact, dense spherical form, fostering understanding of physical changes and material structure.
• Practiced hand-eye coordination and applied steady pressure, which supports muscle strength and dexterity.

Art and Sensory Exploration

• Engaged in sensory exploration by feeling the texture changes from crinkly foil to smooth, shiny surface.
• Enhanced creativity by polishing the surface to a shine, exploring aesthetics and visual outcomes of materials.
• Developed patience and focus through the repetitive action required to achieve a polished finish.

Tips

To deepen the child's understanding, encourage them to experiment with other malleable materials such as clay or playdough to compare how different substances behave when shaped. Introduce simple scientific concepts of physical change versus chemical change by discussing that aluminium foil changes shape but remains the same material. Incorporate storytime or drawing activities centered on metals and recycling, helping connect the activity to broader environmental and material science lessons. Finally, turn the polishing step into a mindfulness exercise, encouraging the child to notice the textures and sounds, which can foster calmness and concentration.
