Simple Machine: Screw
Precision-made wooden models demonstrate basic principles of work, force, and energy. Through hands-on exploration, students learn how machines can change the direction of a force, reduce work, or turn potential energy into kinetic energy. Each model is approximately 7" x 16". Demonstration-size models are also available and measure approximately 15" x 36". Each model comes with a detailed Teacher's Guide.
Includes a Screw model and Teacher's Guide.
