A useful sense

Rory is helping to pack a picnic. She feels a smooth, cool apple and a soft cloth napkin. When she touches a mug of warm water, she notices its warmth. If something is painfully hot or sharp, touch can warn her to move away. Nerves in the skin send messages to the brain, which helps us make sense of what we feel. People who are blind or have low vision may use touch in many ways, such as reading Braille. Readers feel the raised dots with their fingertips. A white cane can help its user notice obstacles, and a guide dog can help its handler travel safely. Everyone uses a mix of senses and tools in their own way.
