Student's Reflection

This project has been an incredibly rewarding journey, combining scientific experimentation, creativity,
and problem-solving. Our primary goal was to develop a candle stand using seafood shell powder and
other readily available materials, with a focus on sustainability and innovation. The process required
iterative refinement of the recipe to enhance the clay’s texture, durability, and functionality, presenting
challenges that demanded patience and perseverance.

One of the most rewarding aspects was collaborating with my groupmates, Ilakkiya and Xinyi, whose
dedication and teamwork ensured our progress. My role required patience, as the clay needed ample
time to dry and harden before it could be decorated. Experimenting with ingredient ratios became a
critical factor for success, while researching the properties and applications of materials like cement
and oil deepened my understanding of the science behind everyday items.

checkAdditionally, I was inspired when our team explored formulating food seasoning powder by
grinding raw prawn shells and mixing them with spices. Initially focused on reducing buffet shellfish
waste, we realized chefs could also generate shell waste while peeling prawns. Working in the food
lab was especially enjoyable, reminding me of my Food & Nutrition classes in secondary school. This
experience not only enhanced my technical skills but also reinforced the value of teamwork, creativity,
and sustainable thinking.

Developing an abrasive detergent using shell powder was an enlightening and rewarding journey,
blending scientific principles with practical applications. This project provided a valuable opportunity
to combine theoretical knowledge with hands-on experimentation, deepening my understanding of
creative problem-solving and the importance of sustainability, particularly in reducing food waste.

The project was driven by a desire to create an environmentally friendly and resource-efficient product.
Shell powder, derived from discarded lobster, crab, and prawn shells, is a natural, biodegradable
material. Its use exemplifies upcycling—transforming waste into valuable resources. This focus on
sustainability resonated with my growing awareness of environmental challenges and the critical role
of science in addressing them.

Presenting the final product and receiving feedback was a moment of pride, reinforcing my
communication skills and commitment to sustainability. This experience inspired me to explore
innovative solutions to real-world problems and continue making a positive impact through science.
