Junior Engineers is an introductory course that teaches kids basic engineering principles such as gearing mechanisms, springs, and cranks. Students build simple machines like Pulley Puppy Dog, Merry-Go-Rounds, and Hockey Players using brightly colored, large-sized TECHNIC® Gears, Pulleys, Wheels, Axles, and more. Junior Engineers provides eye-opening experiences for kids and builds confidence in their abilities to engineer LEGO® builds that move.
