| Summary |
How often do we stop to take a good look at how a bridge is constructed? This program examines the different forms bridges take and explains some reasons for these differences, such as the nature of the terrain they traverse and the weight of the loads they carry. A school's need for a pedestrian bridge over a busy road provides the central story for this program. We identify what makes bridges strong and stable, with reference to the building and joining materials used. Children then test their own model bridges using old counter weights and come up with some solutions for collapsed creations. Meanwhile puppets Dodly and Flyn tackle their own bridge challenge - how to walk their toy dinosaurs over the model railway line without them ending up under a steam train!This 12-part series adopts an investigative approach that helps children to recognise and understand the use of technology around them. Each 15 minute program explores one topic examining how different designs have been created to meet the demands of different users in varied situations. A narrator encourages young viewers to think about the things people have considered when designing technology to meet particular needs.Two monster puppets, Dodly and Flyn, also tackle problems relating to topics, and often come up with some highly imaginative, and sometimes impractical, solutions. These segments reinforce the need to plan a design before making a product.The programs also include children talking about their own designs and ideas and the decisions they have made during the process |
