3 models to build Develop and explore STEM (science, technology, engineering, computing) concepts Aligned to national STEM standards Appropriate for KS2/3 Downloadable booklet guides available Children will learn about gear configurations, gear ratios, rotational speed, mechanical advantage and more Children will have fun and explore STEM concepts while building different geared models! Using the materials included in this set children will be engaged and energised as they further their knowledge and understanding of science, technology, engineering and math concepts. This set includes 140+ parts for a single child or team of two children to build three unique geared models: a Crank Fan, a Car Window and an Egg Beater. Once built, a downloadable booklet guides children through three hands-on, inquiry-based experiments on each of the models. Children will learn about gear configurations, gear ratios, rotational speed, mechanical advantage and more! The Experiment Guide is aligned to national STEM standards and is appropriate for KS2/3.
