In Year 6 we have been learning about reproduction. In this unit we did a short project following the scientific method about life expectancy at birth.

Life expectancy at birth compares the average number of years to be lived by a group of people born in the same year. It is also a measure of overall quality of life in a country.

Aim: The aim of this investigation is to find out about life expectancy around the world and draw a graph representing the differences between different countries.

Materials: We need paper, a pencil, a pen, a ruler, a computer, Internet access and felt-tips.

Hypothesis: What do we think? We have to tell our classmates.

I think life expectancy in developing countries is…
a) lower than in developed countries
b) higher than in developed countries


Method: We use the Internet to search for information on life expectancy at birth. We collect data for life expectancy from ten countries from different continents. We collect data for both men and women.

In groups, we prepare our data and draw a graph representing life expectancy in the countries we have chosen. We use different colours to represent life expectancy for men and for women.

Finally we compare our results with other groups.


Do developing or developed countries have a higher life expectancy?
Why do we think this is?

Who tend to live longer: men or women?
Why do we think this is?

Finally we find out about life expectancy in Spain.

What is the life expectancy for men and women in Spain?
How has life expectancy in Spain changed over the last few decades?

We enjoyed this project. We are really good at browsing the web and searching and collecting data. Some of us even use our netbooks to collect data and draw the bar chart. School projects are cool!
