Corrected sentence:
The tongue is covered with taste buds of different shapes that help us taste the food we eat.
Short explanation for a 6-year-old:
- Taste buds are tiny bumps on your tongue.
- They come in different shapes and help you know if food is sweet, sour, salty, or bitter.
- I changed "shape" to "shapes" because there are many kinds, and "help us taste" is a simpler, clearer phrase than "help us feel the taste."
Even simpler sentence:
Our tongue has many taste buds that help us taste food.
