4th Grade will explore simple machines: Lever, Wedge, Inclined Plane, Pulley, Screw, and Wheel and Axle
They will test force, speed, and motion through demonstrations and design the perfect inclined plane. They will next go into the nature of light and understand the differences between transparent, translucent, and opaque. They investigate reflection using mirrors, lenses, and prisms. Finally them will review vibration demonstrations to illustrate changes in pitch.
