What do you think your body would be like without bones? It’d be all wobbly like jelly.
Let’s learn about bones
Did you know the Human skeleton is made up of more than 200 bones?
Our skeleton has thee main functions:
It supports the body.
It protects organs, for example the ribcage protect the lungs and heart and the skull protects the brain.
It helps the body move, along with muscles.
Can you bend your fingers and feel the finger joins with your other hand?
Muscles help our bones move. If you bend your arm and clench your fist, can you see the shape of the muscle in your upper arm?
How to make sure you have healthy bones
Eat the right foods
Bones need two key nutrients to stay healthy: Calcium and Vitamin D.
We take in calcium through our diet, good sources of calcium include:
- Milk, cheese and other dairy products
- Leafy green vegetables
- Fortified cereals
Vitamin D helps our bodies absorb calcium, Vitamin D is mostly made under the skin in reaction to sunlight, but is also found in foods such as eggs and oily fish.
Exercise helps make bones stronger by increasing bone density, as well as improving muscle strength, and coordination.
Did you know bone density keeps increasing into the mid 20s?
Doctor Role Play
As a fun way to learn about bones we set up a doctor role play area.
We talked about how X-rays are needed to see whether bones are fractured or not and how a plaster cast is used to hold broken bones correctly in place until they are healed.
An X-Ray is a type of radiation which passes straight through the human body. Dense areas such as bone show up lighter than softer areas.
My girls loved putting the casts on their dolls and it led to some great independent role play as they discussed how to make an arm sling for one doll and a wheelchair for another.
I made an easy light box, using a string of battery powered lights in a plastic box for us to view X-rays on which added another fun angle to our play, and really helped my girls visualise the inside of their hands and feet.
Key Stage 1 Science
Animals, including Humans
Identify name, draw and label basic parts of the Human Body.
Describe the importance for humans of exercise, eating the right amounts of different types of food, and hygiene.
Early Years Foundation Stage
Physical Development → Health and self-care → ELG
- Children know the importance for good health of physical exercise, and a healthy diet, and talk about ways to keep healthy and safe. They manage their own basic hygiene and personal needs successfully, including dressing and going to the toilet independently.
