A water gear toy with a shape and color sorter that attaches to the tub. Sort and fit the 3 different gears according to the shapes and colors Pour water and spin the whole gear mechanism, creating a chain of reactions Test tube water container with 1-10 numbered volume marks and a holder that attaches to the tub for playing and storage Promotes fine motor skills, accuracy and hand eye coordination Supports STEM by introducing children to sorting, constructing, and putting physics & engineering into play A water gear toy that supports STEM by introducing children to sorting, constructing and putting physics & engineering into play. Promotes problem solving and reasoning as children create moving experiments with spinning colourful action. Spinning sorter teaches how gears work: spinning one gear will spin the next (engineering). Through ‘Put & take play’ kids learn about different colors, shapes, measurements, quantity, and more. Introduces physics concepts: power of water & circulation. Sort and fit the 3 different gears according to the shapes and colors. Pour water and spin the whole gear mechanism, creating a chain of reactions. Test tube water container with 1-10 numbered volume marks and a holder that attaches to the tub for playing and storage. Creates hours of fun and learning in the bath tub.
