As part of homework we have been building lifting machines. This task is sourced from the Engquest website and has pushed us to think about many science concepts. Congratulations to Taj, Thomas and Stuart who all built successful machines. They used different methods to achieve the task. Taj created a scissor lift using water hydraulics. Stuart also used hydraulics but with a different design. Thomas used a pulley system and worked out a ratio that made it easy to lift the weight. Well done boys.
