This activity illustrates how acids and bases react by using natural indicators. Children will discover how certain liquids change color in response to pH levels, linking chemistry to real-world observations.
Using natural indicators like turmeric and soap engages children in embodied cognition. Visual changes in color make the abstract concept of pH tangible, allowing for meaningful connections to chemical reactions and enhancing memory through dual coding.
1. Gather small cups of lemon juice, baking soda solution, and soap water. 2. Place a spoonful of turmeric in a bowl as your indicator. 3. Add a few drops of each liquid to the turmeric and observe the color change. 4. Record which liquids turn the turmeric red or maintain its yellow color. 5. Discuss what you observed and why the color changed. 6. Can you predict the outcome with other household liquids?
