The importance of materials science and engineering is not always well understood by the general public. The classification of materials in metals, alloys, ceramics, glass, polymers and composites based on their composition and chemical bonding does not allow the importance of materials in technological development to be recognized. Functional classification is much more appealing, but it refers to the role of science and engineering of materials in the background.

The New Frontiers of Engineering Award is an initiative promoted by the Portuguese Association of Engineers (Central Region) which aims to stimulate the interest of students in elementary and secondary education about STEM themes and in the engineering profession. Hydraulic Excavator...The Mean Machine!, was a work developed by students of the 7th year of Colégio da Imaculada Conceição, school and candidate for the prize in 2017. Consisting of the design and construction of a Hydraulic Excavator to realize that the force which is applied to one point is transmitted to another point by means of an incompressible fluid (Pascal's principle)

The New Frontiers of Engineering Award is an initiative promoted by the Portuguese Association of Engineers (Central Region) which aims to stimulate the interest of students in elementary and secondary education about STEM themes and in the engineering profession. Thermoelectric Generator was a work developed by students of the 7th and 9th year of Colégio da Imaculada Conceição school and candidate for the prize in 2016. Consisting of the development of a prototype of a Thermoelectric Generator, demonstrating the importance of the sources and forms of energy, generating sufficient electrical energy to feed an electric motor only through the differences in temperature between 2 water reservoirs.

Any average citizen with an interest in science can make valuable contributions to science through the collection of data and by sharing this data with scientist who can analyze and process.  

The chemical equation resulting from the butane gas combustion is C4H10 + 132O2 è 4CO2 + 5H2O The Combustion is an exothermic chemical reaction between a substance (fuel) and a gas (combustion), usually oxygen, creating, in this particular case, the formation of carbon dioxide and water.

Chocolate M&Ms are covered by a layer of sugar and food colouring. When put into the water, the sugar gradually melts taking with it a certain amount of colouring which, in its turn, is also soluble in water. The sugar flows in the water from areas with a high concentration of sugar to areas with a lower concentration. At some point, the colours do not not mix anymore! A possible explanation is that in the border area between then, the sugar concentration is almost the same, diminishing the tendency of both the sugar and colouring flux.

Making soap bubbles makes any outdoor activity much funnier – specially if there is a smooth breeze to take them to the sky. The size of both the soap bubbles or the huge tubes depends on the used materials as well on the students’ expertise. The soap bubbles have no colour, but their amazing structure and the light properties make visible a complete rainbow. The outer surface that keeps the air inside is a thin water sheet isolated between two thin layers of soap molecules. It’s the way the light interacts with these layers that creates the colours we can see.
