The most effective way to introduce the world of Science to young people is to teach them concepts representing the base for further investigation on the subject; a wider research could take place further on.There are some fields of knowledge regarding our daily life we perceive as a whole; they house several phenomena. For example, the air we breath is not only necessary to life, but it is also the seat of meteorological, sound and electrical phenomena, as well as many others, involving different scientific fields.

SCIENTIFIC COURSESThe same goes for water, energy, light and many others things.The first approach to the study of these subjects has to feature a vision of the subject as a whole, through an experimental and interdisciplinary course.This new series of kits has been designed to offer teachers a valid educational instrument to deal with these phenomena in a unitary way, through a series of simple but effective experiments.

5694 LETÊS LEARN HOW TO MEASURE

The kit „LetÊs learn how to measure‰ has been designed to give compulsory education students a valid support to learn the concept of measure from direct experience, in a simple and effective way. Starting from practical problems, instruments and exercises have been planned in order to develop into the student a „scientific mentality‰ , i.e. an attitude and a habit to express himself in a exact way while measuring . The student will be helped to pass from a qualitative kind of comparison, based on intuitive and visual perception, to a quantitative one, through misuring exercises. Then the student will use instruments to measure the main units of measure.

5607 GEOMETRICAL OPTICS KIT WITH LASER RAY BOX

With this kit you can easily and quickly perform all basic geometrical optics experiments. The laser ray box is endowed with a switch which allows three different beam configurations (1-3-5) The high-quality of optical part allows you to observe the trajectory of reflected and refracted beams. Because of its good quality/price ratio and because of the number and quality of possible experiments, this kit repre-sents the best solution for geometrical optics experimentation for primary and secondary school.
