Work in groups of five. Collect information about global warming. The leader of the group assigns roles to each member. Present the information to the class.

Topic: Global warming

Global warming is the gradual increase in the average temperature of the Earth. It happens mainly because people burn coal, oil and gas, cut down forests, and produce too much pollution. These actions add greenhouse gases to the atmosphere. Greenhouse gases trap heat, so the planet becomes warmer.

Roles in a group of five:

• Leader: organizes the work and gives tasks to each member.
• Researcher 1: finds information about the causes of global warming.
• Researcher 2: finds information about the effects of global warming.
• Designer: prepares a poster or presentation slides.
• Speaker: presents the information to the class.

Main information for the presentation:

• Global warming causes higher temperatures in many parts of the world.
• Ice in the Arctic and Antarctic melts faster.
• Sea levels rise, which can be dangerous for coastal cities.
• There are more droughts, floods, heat waves and strong storms.
• Plants, animals and people have to adapt to climate changes.

What people can do:

• Use less electricity and water.
• Plant trees and protect forests.
• Use public transport, bikes or walk more often.
• Recycle paper, plastic and metal.
• Use clean energy, such as solar and wind power.

Short conclusion: global warming is a serious problem, but people can slow it down if they use natural resources carefully and reduce pollution.
