 You can help a child learn about the sense of taste by trying different foods. You can ask them how the foods taste. Sweet, salty, bitter, or sour. To keep it easy, you can give them only two choices at a time. For example, you might have them taste a lemon and ask, is it sour or sweet? You could give them a salty snack and ask, is it salty or sour? Or, you could give them some sugar and ask, is it bitter or sweet? This activity helps them learn to recognize different tastes.
