Explore STEM concepts while building different vehicle models! Using the materials included in this set, primary-school aged children will be engaged and energized as they further their knowledge and understanding of science, technology, engineering and math concepts. The set includes 130+ parts for a single child or team to build 7 vehicle models with different power sources, including push-power, rubber band power, wind power or a spring motor. Once built, a downloadable booklet guides students through 5 hands-on, inquiry-based experiments on several of the models. Students will learn about potential & kinetic energy, velocity, acceleration, motion, graphing and more! Build 7 working vehicles that demonstrate how they are powered differently. Includes 131 pieces and a spring motor! Up to 4 children can work on 5 Experiments - 1 at a time. Experiment worksheets included for 5 models. For Ages 7+. The Experiment Guide is aligned to national STEM standards and is appropriate for Key Stage 2/3.
