6 ­ Respiration

All living things need energy to live.

The energy comes from Respiration.

Respiration happens in every cell in your body.

           Respiration is the release of energy from food.

During respiration oxygen is needed to break down the food.

Green plants make their own food by photosynthesis.

Animals can eat the plants or other animals.

Aerobic Respiration

You must learn this equation, 

Glucose + Oxygen Energy    + Carbon Dioxide   +    WaterFood  Breathing in Heat, Movement, Growth Breathing out

Aerobic ­ means with Oxygen

When we burn a crisp it needs oxygen to burn and it produces heat energy.

When you do Aerobics you are getting Oxygen

Glucose + Oxygen Energy    + Carbon Dioxide   +    WaterFood  Breathing in Heat, Movement, Growth Breathing out

Respiration Equation

We breath in Oxygen and we eat food.The Oxygen 'burns' the food to make energy.

Carbon Dioxide and water are produced.We can test for these using Cobalt chloride paper and using Limewater.

What gas makes limewater turn milky?Why does the limewater in the first test tube turn milky?Why does the limewater in the second test tube not turn milky?

Test for Carbon Dioxide

We use a chemical called Limewater to test for Carbon Dioxide.

Limewater is a clear colourless liquid.We exhale Carbon Dioxide when we breath out.If we blow into limewater it turns Cloudy/Milky.

Why has the limewater on the left turned milky?

Cobalt Chloride paper turns from blue to pink with water

When we breath out we exhale CO2 and H2O.We take some Cobalt Chloride paper and heat it to get rid of any water.

The paper is a pale blue colour.When we breath on the paper it turns pink.This shows that water is present in our breath.

Which flask would be warmer? Why would this one be warmer?If they were left for too long what might happen?
