Advantages of Streaming (grouping children according to ability)

Some schools separate students according to their academic ability

Teachers can work at the right speed for their students

Teachers can plan more suitable lessons

High-level groups may progress faster

Lower level groups can benefits from a slower pace

Some teachers and parents support streaming for these reasons

Disadvantages of Streaming

Grouping by ability may have a negative impact on students

Children do not want to be seen as less intelligent than others

Streaming could damage students’ self esteem

They may lose motivation

Students from wealthier families tend to be better prepared

Children from poorer families may receive less support from parents

Mixed ability classes encourage everyone to achieve their potential.

Environment

Global warming

Gases such as carbon dioxide trap heat from the sun

This causes global temperatures to rise

This process is known as the greenhouse effect

Human activity is a major factor in the rise of the greenhouse gases

Factories and vehicles produce emissions and exhaust fumes

Many developing countries are becoming industrialized

The number of cars on our streets is growing

Cheap air travel is allowing more people to fly

Effects of Global Warming

Global warming will have a significant impact on our planet

Rising temperature will cause melting of the polar ice caps

Sea levels will rise

We can expect more extreme weather conditions

Flooding and droughts may become more common

Impacts of humans on the environment

The increasing world population is putting pressure on natural resources

Fossil fuels like oil and gas are running out

We are destroying wildlife habitats

We have cut down enormous areas of rainforest

This has led to the extinction of many species of animals and plants

Solutions to environment problems

Governments could introduce laws to limit emissions from factories

They should invest in renewable energy from solar, wind or water power

They could impose “green taxes” on drivers and airlines companies

Government campaigns should promote recycling

Natural areas and wild animals should be protected

Individuals should also try to be greener

We should take fewer flights abroad for holidays

We should take public transport rather than driving

We should choose products with less packaging

We should recycle as much as possible

Waste/rubbish

The amount of waster we produce has increased

This problem is a result of our consumer culture

Products are not made to last

If something breaks, we throw it way and buy a new one

Advertisers encourage is to buy the newest fashions

Packaging is an important part of selling

Most foods are sold in non-biodegradable plastics packaging

The amount of household waste is growing

This waste ends up in landfill sites

Litter

People do not think about the consequences of dropping rubbish

They assume that somebody is pad to clean the streest

Plastic packaging does not break down easily

Most of the litter seen on streets is fast food packaging
