The sense of touch
Activity: To learn more about the sense of touch
The sense of touch helps you to know what things feel like when they are against your skin. When you touch anything, nerves send messages to our brain. If the feeling is unpleasant, the brain sends a message to tell you to take your hand away. If the feeling is pleasant, the brain sends a message to say that you may leave your hand where it is.
Your sense of touch tells you whether something is warm or cold, hard or soft, rough or smooth.
It can also tell you when something hurts you, by feeling pain.
Answer the following questions:
How do you feel about pain?
Can feeling pain be good?
Explain your answer:
In nature, tarantula spiders use their sense of touch to catch their prey, because they hunt at night.
