Explore STEM concepts while building different vehicle models! using the materials included in this set, elementary-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 of 2 children 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! the experiment guide is aligned to National STEM standards and is appropriate for grade levels 3-5.
