This activity helps students understand acids and bases through color changes. By using natural ingredients, they learn about chemical reactions in a hands-on way, connecting theory to observable results.
Using dual coding theory, students visualize chemical reactions through color changes. This active engagement reinforces learning as they see concepts in action, linking abstract ideas to real-world examples through experimentation.
1. Gather red cabbage and chop it into small pieces. 2. Boil the cabbage in 1 liter of water for 10 minutes. 3. Strain the liquid into a bowl; this is your pH indicator. 4. In separate cups, add 1 tablespoon of lemon juice, baking soda, vinegar, and plain water. 5. Pour the cabbage liquid into each cup and observe the color change. 6. Record the colors and label them as acidic, basic, or neutral.
