Year 6. Unit 1. Nutrition: The excretory system + The importance of WATER

1. Create a poster (in pairs) to make people aware of the importance of drinking water.

The importance of water

nAll blood is filtered by the kidneys about 300 times per day.

nOur body is about 2/3 water, so the kidneys also help to maintain a water balance by producing more or less urine, depending on how much water we drink.

Year 5. Unit 1. Living things: The microscope

Cells, as some other living things, are so small that we cannot see them with the naked eye. Howewer, we can observe them through a microscope.
 
A microscope is an instrument with several lenses that make very small objects appear much larger than they really are.

Year 6. Unit 1. Nutrition: The respiratory system

• When we inhale, air enters trough the nostrils and goes to the pharynx.
• From here, air travels down the larynx and the trachea.
• The trachea divides into two bronchi that take air to the lungs.

Breathe in = Inhale

Breathe out = Exhale

• When we breathe in we obtain the oxygen our body needs.
• When we exhale, we expel the carbon dioxide our body produces.

Let's watch these lovely videos about how respiration works!

• Finish exercises (page 5) of your activity book.
• Use the information provided in the classroom's presentation (also included here).
• Watch the videos.
• Optional work: Quiz.
