<b>STEM LEARNING</b> - Science, Technology, Engineering and, Mathematics. STEM aids children in honing their hands-on creative problem-solving skills, innovation, decision making, leadership, entrepreneurship, and more. <br> <br><b><b>Learn how</b></b> to assemble a four-wheel-drive climbing vehicle step-by-step. <br>Learn how electrical energy can be converted into mechanical energy. <br> <br><b>Perfect Gift for Boys & Girls</b>: Our STEM DIY Construction Kit is the ideal gift for children, teenagers, and even adults, age 8+. <br> <br><b>WISHKY STEM toys</b> inspire children to learn with fun. The educational 4WD CLIMBER model assembly kit helps kids develop fine motor skills, boost logical thinking, and learn how to be persistent and patient. <br> <br><b>SAFE 100% NON-TOXIC MATERIALS</b> - This assembly kit is made from non-toxic ABS plastic parts that have been tested and approved by a third-party ASTM (American Society for Testing and Materials) laboratory. <br> <br><b>No special tools are needed</b> - The kit Includes everything you need. <br> <br> Some simple wiring is required to complete the assembly, and one (1) R6/AA/UM3 battery is required. (Kit does not include battery). <br> <br><b> Kids can choose from 3 different chassis angle settings to alter climbing ability: Changing the shaft's attachment position on the wheel alters climbing ability for flat surfaces, low obstacles, or higher obstacles. Position 3 allows the model to climb obstacles up to 5cm (2”). <br> <br><b>We updated the assembly guide</b>. Please read the instructions and work step-by-step to complete the project successfully. <br> <br> <b>IMPROVES SOCIAL SKILLS and TEAMWORK</b> - Awesome activity alone or together with parents, grandparents, or friends to build an array of eye-catching models.<br><br><b>Encourage your kid's </b>constructive play!
