Hydraulic Excavator...The Mean Machine!

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)

M&Ms in the water: Science with creativity

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.

The Archimedes’ law of buoyancy

The video is one of the series of the TV programme “Eureka”, which was projected by the educational Greek television in 1981. Its purpose is to describe the phenomenon of buoyancy that had been discovered by the ancient Greek Mathematician, Archimedes. The video, which comes from the Canadian television TVO, is translated in Greek.    It explains why a metal material, like an anchor, is drown due to the fact that its density is higher than the water’s, and, as a result, the gravitational pull is greater than the force of the water that pushes it upwards. On the other hand, a cork floats due to its lower density, whereas a plastic material would be in the middle of the water without drowning because its density is equal to the water’s. This physical law is known as “Buoyancy”.
