This activity demonstrates the process of filtration and how impurities in water can be removed. By observing the transformation of muddy water into clear liquid, children grasp the importance of clean water and its purification in daily life.
Visualizing the filtration process engages children’s curiosity and promotes active learning. Using embodied cognition, kids see how layers of materials physically separate substances, reinforcing their understanding of water purification methods while exploring real-life applications.
1. Gather a clear plastic bottle and cut the bottom off. 2. Add a layer of cotton at the neck for filtration. 3. Pour layers of sand, gravel, and activated charcoal into the bottle. 4. Prepare muddy water using dirt and pour it into the top of the filter. 5. Collect the filtered water in a bowl below and observe the clarity. 6. Discuss what materials worked best and why.
