The population of a place is all of the people living there.

Life expectancy is the measure of how long a person may live.

The impact of something is the effect it has.

A prediction is a statement saying what you think will happen.

Gases which contribute towards global warming are called greenhouse gases.

Life expectancy (non-statutory)

In this Human development unit, pupils learn to describe the changes as humans develop to old age. In the Evolution and inheritance unit, they will build on this knowledge to learn that living things produce offspring of the same kind, but normally offspring vary and are not identical to their parents

In the New life unit, pupils learnt that animals, including humans, have offspring which grow into adults. In this Human development unit, they will build on this knowledge to describe the changes as humans develop to old age

This unit describes the changes humans undergo from birth to old age. It involves planning scientific enquiries, measuring accurately, recording complex data, and presenting findings. Emphasis is on identifying evidence to support or refute ideas, drawing conclusions, and explaining results.

Subjects which particular individuals may be sensitive to, eg, adoption, migration, bereavement or death, divorce, poverty, deprivation.

Which of these is the main factor contributing to population growth?

the increase in average human height over time

the increase in average human mass over time

the increase in the number of humans on Earth over time

the increase in life expectancy of humans over time

Which of these things would not increase as the global population grows?

Which of these things would lead to more greenhouse gases being produced?

make predictions about the population size of the future

see how big the global population was in 1700

observe how population has changed over time

understand the reasons for population growth

Alex has created a line graph showing changes in population from 1900 – 2023. Which of these can he do using his line graph?

The planet that all humans live on is called {{}}.

the measure of how long a person may live

the measure of how many humans there are on Earth

the measure of a person’s height over time

When something increases, what does this mean?

Scientists can use line graphs to make predictions about what may happen in future. What is a prediction?

Life expectancy is now {{}} than it was in the past because of a lot of factors, such as better diets and more access to healthcare.

Which type of diagram is best for showing how something changes over time?
