Core Skills Analysis
Science
- Eligh learned about the process of filtration and how it can be used to separate particles from a liquid using a multi-stage filter.
- He explored physical changes by observing the difference in the water before and after passing through layers of paper and turmeric particles.
- He used sensory evaluation (smelling and tasting) to assess changes in the filtered water, connecting scientific observation with practical, real-world experiences.
- Eligh demonstrated curiosity and critical thinking by analyzing the effectiveness of the filtration process and noting changes in taste and smell after purification.
Critical Thinking and Observation
- Eligh refined his observational skills by closely inspecting the water as it passed through the four-part filtration tube, noting visual changes.
- He practiced using multiple senses (sight, smell, taste) to gather data, which strengthens holistic analysis and subjective evaluation.
- The activity encouraged him to hypothesize about the effects of turmeric and filtration on water quality and then test those hypotheses.
- He showed patience and focus in carefully conducting the step-by-step filtration and sensory testing review.
Tips
This activity can be extended by encouraging Eligh to create a simple experiment comparing different filtration materials (e.g., sand, charcoal, cotton) and their effectiveness at cleaning water. Introduce a scientific journal to record observations, hypotheses, and results to develop documentation skills. To deepen understanding, discuss the role of turmeric and whether pigments or chemicals could affect water properties beyond physical filtration. For a fun extension, Eligh can try to design his own multi-stage water filter and test its efficiency against other designs. Bringing in lessons about water pollution and the importance of clean water globally can connect this concrete experience to wider environmental science topics.
