План-конспект открытого урока в 11 классе по теме «Climate Change»

Good morning, everybody! Glad to see you all. Take your seats please and let’s get the ball rolling.

Today I suggest discussing one of the most troublesome global problem. That’s climate change (указывает на экранную заставку). We’ll be talking on its causes, effects and possible solutions of the problem.

To begin with, let’s recall the causes of climate change. Will you fight a duel?

(2 teams name the causes in turn:

• greenhouse gas emissions from burning fossil fuels to produce electricity, industrial and agricultural goods.  It covers the Earth like a blanket and causes global warming,
• changes in the solar radiation,
• volcanic activity: eruptions heat the atmosphere,
• deforestation: trees absorb CO2 from the atmosphere. When they are cut down, the carbon stored in the trees is released into the atmosphere,
• fertilizers used in agriculture produce nitrogen oxides emissions,
• increased livestock farming: cows and sheep produce methane digesting their food
• the use of aerosol sprays, fridges, air conditioners: they all emit CFC gases

T: 1, 2, 3 … Team 1 wins the 1st part of the duel. Congratulations! Now, for the 2nd part. You have 1 minute to list as many consequences of global warming as possible. The team with more effects wins.

(1-ozone depletion   2- diseases like asthma, skin and lung cancer or leukemia   3 – increased smog   4- droughts   5- famine  6 – severe storms  7 – more frequent cyclones  8 – water scarcity  9 – forest fires  10- melting glaciers  11 – sharp rise of the water level on the planet  12 – floods  13- declining biodiversity)

T: Team 2 wins and the score becomes equal. Well done, all of you!

You’ve mentioned declining biodiversity as 1 of the climate change effects. A good example of this is the Great Barrier Reef of Australia. You’ve read a text about it. Tell me how it has been suffering from global warming.

P1: The ideal water temperature for coral growth is +26 to +27C When the sea temperature rises even by 1 degree and keeps like that for only 6 weeks, corals begin to bleach and soon die. Since 1995 the GBR has lost half its coral!

P2:  The next big threat is a crown-of-thorns starfish that eats corals due to the lack of algae, its main food. An adult starfish can eat up to 10 sq.m of coral

P3: Other threats are:  polluted water, more severe cyclones, ocean acidification and reef erosion

T: Well, let’s watch a short video about the Reef. Your task is to compare the information of the film to that of the home text and tell me what’s missing in the video.
