Science Aids
Through of our many years of experience in supervising educational material on the science lesson and following suggestions made by teachers dealing with the subject, we have made a series of constructions - aids. These constructions aim to relieve the tutor from the time-consuming process of finding the materials and assembling the experiments and saving him time to better and easier the course. These aids are our own construction with simple materials, as required by the instructions of the course books, and are available only on request.
