Science
- The child learned about the concept of acids and bases.
- They learned how to use litmus paper to test for acidity or alkalinity.
- They learned that acids turn litmus paper red and bases turn it blue.
- They learned about the pH scale and how it measures the acidity or alkalinity of a substance.
For continued development, the child can explore other pH indicators such as red cabbage juice or universal indicator solution. They can conduct more tests using different household substances and observe the color changes on the indicators. They can also research and learn about the real-life applications of acid-base tests, such as in environmental monitoring or medical diagnostics.
