In this sequence of two lessons, students investigate trigonometric and Pythagorean relationships through two contexts: researching and building a model zipline ride and outlining a proposal for glider poles. In the first lesson, students apply trigonometric and Pythagorean relationships to investigate the dimensions of ziplines around the world. They then plan, diagram, model and construct a zipline for a doll. In the second lesson, they investigate how 'glider poles' allow gliding mammals to cross wide roads. They design a pair of glider poles appropriate for the animals and roads in their region using their knowledge of trigonometry, particularly angles of elevation and depression. The lessons are outlined in detail including curriculum links, vocabulary, sample answers, discussion points and student resources. This sequence is part of the reSolve: Maths by Inquiry program.
