Here are three ways to ask the same question in simple words:

  • What body part lets you taste food?
  • Which part of your body helps you know if something is sweet, sour, or salty?
  • What do we use to taste things?

Short answer: The tongue helps us taste.

Step-by-step explanation for a 7-year-old:

  1. The tongue has tiny bumps called taste buds. You can’t see them easily, but they are all over the top and sides of your tongue.
  2. Each taste bud can tell one of the main tastes: sweet, sour, salty, bitter, or umami (a savory taste).
  3. When you eat, the taste buds send a message to your brain through tiny nerves.
  4. Your brain puts the message together and tells you what the food tastes like.
  5. Also, your nose helps a lot with flavor. Smell and taste together make food taste richer.

Try this quick test (with a grown-up nearby): taste a small piece of apple, then a slice of lemon. Your tongue will notice the difference because of the taste buds!
