What Crafty Clover says in this video

Intro

Hey there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do we grow?

The Big Idea

You grow because your bones get longer, following a plan inside your body. Special parts of your bones called growth plates add length while you are a kid. Good food and sleep give them the fuel they need. Your body is always busy building a bigger you.

Food and Sleep Fuel

Step one: food and sleep fuel your growing. Healthy food gives your body building materials. Sleep gives it time to use them. Sleep is when growth hormone is especially active.

Growth Plates Work

Step two: growth plates work. Near the ends of long bones are soft zones called growth plates. They make new bone tissue, bit by bit. The plates close when you finish growing up.

Bones Get Longer

Step three: bones get longer. As the plates add length, your bones stretch out. That makes you taller, a little at a time. After that, your bones stop getting longer.

A Closer Look

Let's take a closer look at growing. Food and sleep are the fuel that starts it all. The growth plate adds new bone at the ends. And one day, your clothes get short, which means you grew. It is a long project, and it takes years.

Quick Facts

Quick facts! Most kids grow in spurts, not a smooth line. Some months you may grow a lot, and other months hardly at all. Every kid grows at their own pace, and that is normal. If you have worries about growing, talk to a grown-up or a doctor. Growing is something your whole body does, from head to toe.

Think Like a Scientist

Now, think like a scientist! With a grown-up, find a wall where you can mark your height. Stand tall, and mark your height. Do it again once a month. How does your growth look over time?

Outro

You are growing in your own way, and that is wonderful! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
