The 5 Food Groups

Why is the food we eat important?

The food we eat should provide us with the energy and nutrients we need to grow and keep our bodies healthy.

Each one of the five food groups is important:

Fruit and vegetables, for example, apples, bananas and broccoli, give us
vitamins to keep our bodies working and help our immune system and fibre to aid digestion.
Carbohydrates, like pasta, bread and rice, keep our energy levels up.
Proteins, such as meat, beans, and eggs, build healthy muscles and allow our bodies to grow and repair.
Dairy, like milk, cheese and yoghurt, gives us calcium for strong teeth and bones. Many dairy-free alternatives have calcium added to them too.
Fats and oils, for example olive oil and butter, act as on energy store.

BLOOD

What is in our blood?

The circulatory system.

We explored how blood travels through our body.

Deoxygenated blood travels into the right atrium of our heart, then through the right ventricle. It leaves the heart through the pulmonic valve and pulmonary artery to the lungs. In the lungs the blood cells collect oxygen and travel back to the heart. The oxygenated blood re-enters the heart into the left atrium then travels to the left ventricle before leaving via the aortic valve. From the aorta the oxygenated blood travels around the body releasing oxygen and collecting carbon dioxide. The deoxygenated blood then travels back to the heart and the system starts again.

Today we enjoyed exploring Charles Darwin’s Natural Selection Theory.
Our activity focused on bird beaks and if beak shape and size determines what kind of food a bird eats.
We made some interesting discoveries to prove the fact that species adapt to suit their environment.
