This short video shows how cyclists combat wind resistance. Rod Ellingworth, a professional cycle racer 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.
One idea could be to show the clip without sound on and ask children to think about the ways in which the bike and cyclist reduce wind resistance. Another idea is to provide groups with cards showing different bicycles and ask them to order them from fastest to slowest. Cards could include: a tricycle, a bike with stabilisers, a racing bike, a bike with a trailer on, a mountain bike. This discussion will get children thinking about air resistance and other factors which can affect how fast they can go.
