Projection Screen 36 x 48" LabLearner easily inclinable surface for dynamic-cart

easily inclinable surface for dynamic-cart and momentum experiments in mechanics units

Designed to electrolyze water into separately collected hydrogen and oxygen

sized for individual student-lab use in simple-machines units

paired with 4mm sockets so iron-filing patterns can be mapped around a current-carrying conductor for Oersted's experiment

Adjustable mass on one fork shifts its 440Hz pitch by a few hertz
