Curious kids build a 69-piece robotic dog and explore how alternative energy powers movement! Tweens experiment with three energy sources to power Robo Dog's movement: solar energy, salt water, and battery power. They'll learn how energy converts into motion through hands-on mechanical engineering and explore renewable energy concepts in a fun, approachable way. This science kit makes a great birthday gift that encourages experimentation, critical thinking, and STEM curiosity. It's ideal for independent play, family projects, homeschooling, or classroom learning. Requires 2 LR44 batteries, included. From Elenco Electronics Inc, for ages 8+ yrs.
