Year 6 Science Worksheet (Age 10): Nosebleeds — Causes, How They Happen & First Aid + Interactive Quizzes

Part 1: Why Do Noses Bleed?

Have you ever wondered why nosebleeds happen? Inside your nose, especially on the wall that separates your two nostrils (called the septum), there is a rich supply of tiny, delicate blood vessels. Think of them like a fine net of tiny water pipes sitting very close to the surface. Because they are so fragile, they can break easily, causing a nosebleed.

Many things can cause these vessels to break. Here are a few common reasons:

• Dry Air: When the air is very dry (like in winter or in a centrally heated room), the inside of your nose can get dry and cracked, making the blood vessels more likely to break.
• Nose Picking: A sharp fingernail can easily scratch the delicate lining of the nose.
• Blowing Your Nose Too Hard: The pressure from a really hard blow can sometimes be too much for the tiny vessels.
• A Bump or Knock: Getting hit in the nose during sports or playtime can cause a bleed.

Activity: Circle the Causes

Part 3: Nosebleed 911 - What to Do!

Knowing what to do can make a nosebleed stop much faster. Follow these steps like a first-aid hero!

1. Stay Calm: Don't panic! Most nosebleeds are over in a few minutes.
2. Sit Down and Lean FORWARD: Leaning forward makes the blood dribble out of your nose instead of down the back of your throat. Swallowing blood can make you feel sick.
3. Pinch Your Nose: Use your thumb and index finger to pinch the soft part of your nose, just below the bony bridge.
4. Hold and Breathe: Keep pinching for at least 10 minutes without letting go to check. Breathe through your mouth.
5. Ask for Help: Always tell a grown-up what has happened.
