Butterflies are beautiful to see but how do they get here? Growth and change become exciting lessons with this STEAM wall accessory board that takes youngsters through the phases of metamorphosis. Real life specimens, from egg, to chrysalis, to caterpillar, to an adult butterfly are encapsulated in clear acrylic compartments that light up with the push of a brightly colored button (2 AA batteries required, not included). This interactive busy board will hold youngster's attention to help them learn in fun and creative ways. The sturdy wooden board features kid-friendly, smoothly rounded corners for safe play and installs almost effortlessly on our train STEAM wall system, 3 panel wall system, or freestanding art easel but can be used on the floor or at an activity table as well. Regularly wipe clean with a damp cloth and dry for long-lasting use.
