An interview with Rod Ellingworth, a professional cycle racer. He explains how wind resistance can affect the speed of his bike. The bike moves through the air really quickly so there is less resistance. It also has smooth curves so the air flows over it smoothly. The handlebars are designed to enable the cyclist to sit in a tuck position allowing the air to flow over the top. The clothes they wear are tight and their shoes are covered over to help the air flow smoothly over the body.

This clip can be used as a stimulus to create thinking about wind resistance. Teachers could use the clip to develop questioning into how a cyclist prevents wind resistance from slowing them down. Children could compare this to other sports where wind resistance might affect skills. Children may develop their understanding by linking streamlining designs to other objects such as cars.
