This activity helps students observe color changes in natural indicators from fruits. Understanding pH levels connects them to everyday chemistry and its relevance in life.
Using everyday materials like fruits as indicators simplifies abstract concepts of pH. By observing vivid color changes, students engage in active learning through embodied cognition, making chemical properties memorable.
1. Gather 1 cup of cabbage leaves, 1 lemon, and 1 cup of water. 2. Boil cabbage leaves in water for 10 minutes to extract color. 3. Strain the mixture to get the indicator juice and let it cool. 4. Squeeze the lemon into a separate cup. 5. Pour a little cabbage juice into the lemon juice and observe the color change. 6. Repeat with other household items like baking soda or vinegar.
