This activity teaches students about pH levels and the properties of acids and bases. By using natural indicators from flowers, children can visually see reactions and understand how substances interact in everyday life.
Using flowers as indicators taps into embodied cognition, allowing children to connect chemical properties with tangible experiences. The visual transformation of color reinforces learning through dual coding, linking abstract concepts with vivid imagery.
1. Collect 2-3 purple or blue flowers (like hibiscus or butterfly pea). 2. Boil the petals in 1 cup of water for 5 minutes to extract color. 3. Strain the liquid into a glass to create your natural indicator. 4. Test the indicator with various household items: add lemon juice (acid) and baking soda (base) separately. 5. Observe the color change and note your findings. 6. Share with family: which item changed the color of the indicator?
