Enthrall young physicists who already have a basic grasp on physics but crave an understanding of advanced concepts like hydraulics, pneumatics, and oscillation! Using a 96-page full-color manual, students first build smaller models and become familiar with the properties of air and water through 17 hands-on experiments. As skills progress, they construct 17 larger models of complex marvels of real-world engineering – a wind tunnel, pneumatic shocks, a hydraulic lift and more! They’ll investigate how air and water rest and flow, how forces work on them, and what energy they possess. Kit includes 212 pieces and manual. See manual for full contents list. Elementary and up.
