Part 1: Read the Article
As you read, underline or highlight at least three key facts you think are most important.
The Brain's Midnight Cleanup Crew
Have you ever wondered why you need to sleep? It might feel like you're just turned off for eight hours, but your brain is actually one of the busiest places in your body while you sleep. Think of it as a city that shuts down its streets at night for a very important cleanup and repair mission.
One of sleep's most critical jobs is to clean the brain. During the day, as your brain works hard helping you learn, think, and move, it produces waste products. While you sleep, a special system called the glymphatic system kicks into high gear. It acts like a microscopic cleanup crew, flushing out these harmful toxins. Without this nightly cleaning, the waste can build up and make it harder to think clearly.
Sleep is also essential for learning and memory. When you learn something new, the information is temporarily stored in your brain. During sleep, especially in a stage called Rapid Eye Movement (REM) sleep, your brain sorts through the day's events and decides which memories to keep. It strengthens the important connections and gets rid of the less important ones. This process, called memory consolidation, is why studying before a good night's sleep can help you remember information for a test.
For kids around age 11, getting the right amount of sleep is crucial. Experts recommend between 9 and 11 hours of sleep per night. This ensures that the brain's cleanup crew has enough time to do its job and that your memories are properly filed away, leaving you refreshed and ready for a new day of learning.
Part 2: Fact or Opinion?
Reporters must know the difference between a fact (something that can be proven true) and an opinion (a personal feeling or belief). Read the statements below. Decide if each one is a Fact from the article or an Opinion about the topic.
Hint: A fact can be found directly in the text. An opinion expresses a judgment, like whether something is boring, cool, or the best.
| Statement | Fact or Opinion? |
|---|---|
| 1. The glymphatic system flushes toxins from the brain during sleep. | |
| 2. Dreaming during REM sleep is the most interesting part of sleep. | |
| 3. Experts recommend 9-11 hours of sleep for 11-year-olds. | |
| 4. Waking up early is awful, even if you get enough sleep. | |
| 5. Sleep helps the brain with a process called memory consolidation. | |
| 6. Learning about the brain is more boring than learning about space. |
Part 3: Build a Summary (Guided Practice)
Now, let's practice organizing the main ideas. Fill in the blanks below using key details you found in the article. This will become a basic summary.

Example Summary: The article "The Brain's Midnight Cleanup Crew" explains that sleep is crucial for brain health. During sleep, the brain cleans out harmful waste products through the glymphatic system. Sleep also plays a key role in learning by strengthening important memories in a process called memory consolidation.
