Welcome to the Science Page
Our current Science topic is ‘Animals including Humans’. So far, we have learnt all about what makes a balanced diet – A diet that has the right amounts of nutrients.
Now we will find out about the Human Skeleton and Muscles.

Your ribs come in pairs, and the left and right sides of each pair are exactly the same. Most people have 12 pairs of ribs, but some people are born with one or more extra ribs, and some people might have one pair less. Babies are born with about 300 bones but adults only have 206.
Great facts Celestine. Interesting that babies are born with more bones than adults isn’t it!
Bones give our bodies their structure, help us move, but also produce blood cells in bone marrow. They are living things: they need calcium-rich foods o grow, but can also break. Thankfully, bones can regenerate and grow back together again!
Great information Helena. Do you remember what foods/drink contain calcium?
Bones protect many internal organs. Bones protect the chest by surrounding the heart and lungs and the skull bones surround the brain to protect it.
Yes Karolina, bones protect many internal organs! Do you know which internal organ is the most delicate?
What are bones made of ?
If you’ve ever seen a real skeleton or fossil in a museum, you might think that all bones are dead. Although bones in museums are dry and hard or crumbly, the bones in your body are different. The bones that make up your skeleton are all very much alive, growing and changing all the time like other parts of your body.
The outer surface of bone is called the periosteum (say pare-we-oss-tee-um) it’s a thin, dense membrane that contains nerves and blood that nourish the bone.
Great facts about bones Chloe. I’m glad you put how to pronounce periosteum, it’s a tricky word isn’t it!
The lower jaw bone is the only bone in your head you can move.
Our bones give our body shape, and support and protect our organs and systems.
Periosteum is the thin, dense membrane on the surface of the bone contains nerves of blood vessels the help nourish bone tissue.
The soft bone marrow, which is found inside many bones, makes most of the body’s red blood cells.
Lots of interesting facts Year 3 ?
I found out lots of interesting facts about bones today, which are:
1. Babies have 305 bones and adults have 206, you might think it’s weird but baby have much smaller, softer and flexible bones than adults.
2. Most of the white and red blood cells are produced in bone marrow, which is jelly like.
3. The only bone in the skull can move is the jaw bone.
4. The fingers have 3 bones and the thumb has 2 bones.
Well done Angie!
The hand and feet contain over half of the body’s bones. Almost every bone is connected to another bone. Every second our bone marrow produce two million red blood cells.
Interesting facts Angie and Chloe, why do you think hands and feet contain so many bones?!
Yesterday me and my family watched a documentary on how chocolate is made. It is a very long and complicated process to transform cocoa beans to the chocolate we are eating today. The cocoa beans don’t taste like chocolate at all, instead they taste very sour. Did you you know it is quite rare to get these beans just to make chocolate. The dark chocolate has a lot of cocoa beens and it has no cocoa butter it also has some sugar. In the milk chocolate there is less cocoa beans but still plenty too. It has some sugar and has cocoa butter too. If it’s good for you or not and you don’t know it depends on how much sugar there is in the chocolate.
This is super interesting!
Your bones protect your body. A skeleton is a frame work where all our muscles grow around. A skeleton grows and helps us to move. Our skoul is just like a helmet. The biggest bone in your body is femur. It is found in your upper leg. When you are born you have 305 bones but you have around 206 when you get older. Every single person has a skeleton made up of many bones. These bones give your body structures and protect your internal organs. Our body shape protect our organs and system. Our tongue is also a muscle. Our muscles nearly weigh half of our body.
There are 26 bones in the feet and 27 bones in the five fingers of the hand. Our feet and hand are very flexible. You can point your toe or finger stand on your toes or grab a hand, move your ankle and wrist up and down and left to right. Thanks to those bones and joints in our feet and hand, we can walk, run, jump and move our palms. This flexibility is possible because the foot and hand has many bones, joints, muscles, and soft tissues.
