Slide2Carbon Monoxide, Haemoglobin & Global Dimming
Slide3Deepen knowledge and understanding of the effects of pollutants.
Identify the properties of carbon monoxide.Describe the process of global dimming.
Explain the effect of carbon monoxide on the human body.
Slide4Incomplete Combustion
Describe
what happens during incomplete combustion. You must include the products that are formed and a word & symbol equation (two equations!
Slide5Slide6Carbon Monoxide
Carbon monoxide is a toxic gas.
It is
colourless and odourless.
Slide7Carbon Monoxide
Carbon monoxide is absorbed in the lungs and binds with the haemoglobin in our red blood cells.
This reduces the capacity of the blood to carry oxygen.
Slide8Global Dimming
Make notes on the video ready to answer questions later!
Slide9What is global dimming?
Are global warming & global dimming related?
Is global dimming a cure for global warming?What causes global dimming?What happened on September 11th 2001?
How did this event help climate scientists to study global dimming?What did the scientists find out?How is this evidence for global dimming?Why should we be worried about global dimming?Why is rain useful?
Is there any good news?What is global brightening?Why did global brightening start happening?Why do we need governments to work together
?
Slide10Global Dimming
Tiny particles that are released when fuels are burned cause global dimming.
Like global warming, this process may change rainfall patterns around the world.
The amount of sunlight reaching the Earth’s surface has decreased by about 2 per cent every ten years, because more sunlight is being reflected back into space.
The particles from burning fuels reflect sunlight, and they also cause more water droplets to form in the clouds. This makes the clouds better at reflecting sunlight back into space.
Slide11Create
a mind-map to highlight the key facts about carbon monoxide and carbon monoxide poisoning.
Describe the process of global dimming.
Explain how particulates are reducing the amount of light reaching Earth and describe the problem for plants.
Challenge: Suggest
how global dimming may effect food chains.
