What Makes Our Bones Strong?
Bones are like the strong frame of a house, holding up your body and keeping everything in place. But what makes our bones strong? Let's take a deep dive into the amazing world of bones!
Hello my friends!
For a quick note, welcome to Tidbits with Titus, a podcast and newsletter where we tackle the big, curious questions kids ask every day in fun, bite-sized ways! I’m Alexander Titus, but I go by Titus. I’m a scientist, adventurer, and a huge fan of making science, technology, and life accessible to all ages. From “How does electricity work?” to “What are taxes?” and even “Why is the sky blue?” I’m here to dive into these wonder-filled questions with engaging stories and simple explanations that spark curiosity and make learning a joy. This effort is all about creating a space where families can learn together, discover the magic of the every day, and find thoughtful ways to explore the world’s big mysteries.

What Are Bones Made Of?
Bones might look hard and solid, but they are actually made up of different materials that work together to keep them strong and flexible. Here are the main parts:
Calcium – This mineral gives bones their strength and hardness, just like bricks in a building.
Collagen – A stretchy protein that makes bones flexible so they don’t break easily.
Bone Marrow – The soft center of bones where blood cells are made!
Water – Yes, bones contain water too, helping to keep them healthy!
How Do Bones Grow?
Did you know that when you were a baby, you had about 300 bones? But as you grow, some of them fuse together, and adults end up with 206 bones! Your bones grow bigger and stronger as you eat healthy foods, move your body, and get plenty of rest.
Inside your bones, there are special cells that work like tiny builders:
Osteoblasts – These are the builders, making new bone material and helping bones grow strong.
Osteoclasts – These are the cleaners, breaking down old bone so new, strong bone can take its place.
What Helps Bones Stay Strong?
To keep bones strong, they need the right nutrients and activities! Here are some of the most important things that help bones:
1. Calcium-Rich Foods
Calcium is like the superhero of bones! It makes them strong and helps them heal if they break. Here are some tasty foods filled with calcium:
Milk, cheese, and yogurt
Leafy greens like spinach and kale
Almonds and sesame seeds
Fish like salmon and sardines
2. Vitamin D
Vitamin D is like calcium’s best friend because it helps the body absorb calcium. You can get vitamin D from:
Sunlight! Just 10-15 minutes outside can help your body make vitamin D.
Foods like eggs, fish, and fortified cereals.
3. Exercise and Movement
Bones love to move! Running, jumping, and playing outside help bones grow stronger. Some great bone-strengthening activities include:
Running and playing tag
Jumping rope
Dancing
Climbing and swinging on monkey bars
Fun Bone Facts!
Your femur (thigh bone) is the strongest and longest bone in your body!
Your ears have the smallest bones—the tiniest one is called the stirrup bone, and it’s smaller than a grain of rice!
Your body replaces old bone cells with new ones all the time—this means you get a new skeleton about every 10 years!
What Happens if Bones Get Weak?
If we don’t take care of our bones, they can become weak and more likely to break. That’s why it’s super important to eat healthy foods, get enough sunlight, and move every day.
When bones don’t get enough calcium and vitamin D, they can become soft or fragile. This can lead to a condition called osteoporosis when people get older, making their bones more likely to break.
How Do Broken Bones Heal?
Sometimes, even strong bones can break. But don’t worry! Bones are amazing healers. Here’s how it works:
Blood rushes to the broken bone, forming a clot to protect the area.
New bone cells start building, creating a soft bridge called a callus.
Over time, the callus hardens, and the bone becomes strong again!
Doctors use casts to help keep the bone in place while it heals.
Experiment: See How Bones Absorb Calcium!
Want to see how calcium makes bones strong? Try this fun experiment at home with an adult!
You’ll Need:
A glass of vinegar
A clean chicken bone (from a cooked chicken leg or wing)
A glass jar
Steps:
Place the chicken bone in the jar and cover it with vinegar.
Leave it for a few days.
Take the bone out and try to bend it.
What Happens? The vinegar removes the calcium, making the bone soft and bendy! This shows how important calcium is for keeping bones strong.
Conclusion
Your bones are like the superheroes of your body! They hold you up, protect important organs, and even make new blood cells. To keep them strong, eat calcium-rich foods, get plenty of sunshine, and move your body every day. If you take care of your bones, they will take care of you for a lifetime!
