This slightly more challenging activity gives an opportunity for pupils to examine data and then consider all different kinds of influencing factors in order to predict what will happen another 64 years on. It is designed to be accessible to primary pupils at Key Stage 2.

Now and Then
In 1908 the Olympic games were held in London, that's just over 100 years ago. Then just after World War II they were held in London again in 1948.
Here are the results from some track events:
|100 metres||10.8 secs||10.3 secs|
|200 metres||22.6 secs||21.1 secs|
|400 metres||50.0 secs||46.2 secs|
|800 metres||112 secs||109 secs|
|1500 metres||240 secs||229 secs|
So the Olympic games of 2012 will be another 64 years on. What do you think the results will look like?
Perhaps more importantly, what's the reason for your answer?
