Turmeric and Lemon Juice Experiment

The video tutorial introduces the concept of acid and base tests using turmeric as a natural indicator. The teacher explains how turmeric changes color when a base is added, turning red, and then reverts to yellow when an acid like lemon juice is added. The lesson includes a step-by-step experiment demonstrating these changes, emphasizing the magical aspect of science. Students are encouraged to try the experiment at home.
