SERIES Simple Machines: Screw

SERIES Simple Machines: Screw

The screw is one of the 12 functional experimental models of our SERIES SIMPLE MACHINES. Like all simple machines, it can be used to demonstrate the gain in force, calculate it, and find practical applications. Examples of its applications are jar lids, drill bits, meat grinders, corkscrews and, of course, screws...

In addition, this experimental model comes with an instructional guide including theoretical discussion and ready-made worksheets for the teacher and student (separate!):

1. How large is the gain in force?
2. Practical use of the gain in force.

All simple machines in this series are made from a friendly material - wood. Dimensions: 19x10x11 cm. Weight: 680 g.

This teaching aid seems so simple? That's good! Because this is a MODEL OF A SIMPLE MACHINE!

Simple machines are all around us, even in very COMPLEX devices. We will find them even in ourselves... All you have to do is extend your arm and bend it at the elbow.

Experiment with our simple machines - we include detailed worksheets for teachers and students.

Show serious formulas in practice! Only such learning makes sense.

The SERIES SIMPLE MACHINES includes 12 models of simple machines - 6 basic and 6 complex, designed for practical experience of their operation, illustrating the gain in force achieved thanks to using a given machine, but also for calculating this gain based on specific settings of the machine in the form of our model.
