This week in Design Technology, Year Two have been designing and making their own toy fire engines. First, the children researched existing toy fire engines and thought about what they liked and disliked about some different designs. Then, they used this to help them to design their own toy fire engines, complete with a mechanism. The boys and girls found out about how wheels can turn on an axle to help the wheels turn at the same speed and at the same time. Then they assembled their own chassis and axles. Next, the children used cardboard boxes to create the body of the fire engines and decorated them using different coloured paper to make them look like a real fire engine. They added a hose made of string and lights made of blue paper. They then added a winding mechanism to enable their ladders to move up and down. This was quite tricky but the children persevered and they were very proud of their finished products.
