Use the video to write 3 facts

about the number of

people on Earth.

World Population Clock

What does it actually tell us??

Discuss your ideas with your neighbour for 1 minute.Consider the key words ‘birth rate’, ‘death rate’, ‘rapid growth’. Try to use them in your discussion.

Write ONE PARAGRAPH to explain what is happening to the world’s population, using the

key words.

A Future Projection…

You have ONE MINUTE to predict what the world’s population will be (according to the World Population Clock) by the end of this lesson.

Make a note of this number, and keep it safe.

Use the data on the next slide (or this graph) and enter it into Excel.

Create a cumulative line graph to show how global populations have increased in LEDC and MEDC countries (1700 – now)

Describe the changes in this graph from Year 00AD to now.

Population growth 1700–2050

Year HIC (pop. in billions) LIC (pop. in billions) World pop. in (billions)

1700 0.1 0.5 0.6 1750 0.2 0.6 1800 0.3 0.7 1850 0.4 1.0 1900 0.6 1.2 1950 0.8 1.7 2000 1.3 4.7 2050 1.3 7.8 9.1

Population growth has become _____________.

Since 1800, the world’s population has _______________.

This is known as __________________ growth.

FUTURE????

LIC

HIC

Another key term:

• FERTILITY RATE- This is the average number of births per woman in a country’s population.

1. How might a country’s fertility rate affect how fast the population grows?

2. What can you say about fertility rates in LIC’s, compared to HIC’s?

To finish:

• ‘Describe how the global population has changed since 1800’. (3 marks)

PEER MARK:1) Use of a trend- the way it has changed over

time eg, increased rapidly and now slowing.2) Growth far higher in LEDC’s than MEDC’s.3) Use of figures to back up your answer.

Population Estimates:

• According to the World Population Clock, the population is…
