The Solar Robot
Last Tuesday, Maya felt uncertain about her science project. Her first prototype was incomplete, and her partner had misunderstood the written blueprint. Instead of feeling hopeless, Maya decided to rebuild their small robotic car. With careful testing, she installed a rechargeable battery pack. When the judges inspected her invention, Maya answered questions confidently. Her persistence led to a remarkable victory!
