Cycling to the South Pole

Topic: 3C Characteristics of materials

Blue Peter presenter Helen Skelton has become the first person to use a bike on part of an expedition to reach the South Pole. It was a journey of 500 miles (805km) across Antarctica and she cycled for large parts of it, as well as snow-kiting and walking. This trek was for Sport Relief. In Jan/Feb, the average temperature in Antarctica is -25C, but can drop to -50C. Severe coastal winds come from cold air flowing down off the interior ice sheet. Wind speeds can reach up to 125mph (201km/h) and average about 80mph.

In this activity children will consider the features of a bike made for these conditions and what materials might be used and why.
