8.1 Lesson 5 READING : How Does Touch Work?

How do blind people read using their sense of touch?

• By tasting the letters

• By feeling patterns of raised dots

• By smelling the words

• By listening to audio recordings

What is the coding system that allows visually impaired people to read using raised dots?

• Secret code

• Braille

• Binary code

• Morse code

Can sighted people recognize objects using only their sense of touch?

• Yes, they can identify objects using touch

• No, touch alone is not enough to recognize objects

• Yes, but only if they have special training

• No, only blind people can do that

Why are there so many pain receptors in our skin?

• To enhance our sense of taste

• To warn us of potential harm or injury

• To help us regulate body temperature

• To make us more sensitive to touch

What happens if someone can't feel pain?

• They become superhuman

• They are unable to move

• They develop heightened senses

• They are at risk of further injury

What do the heat and cold sensors in our skin help us with?

• Improving our sense of taste

• Regulating body temperature

• Detecting danger

• Enhancing our sense of touch
