Bridge Design

Os dejo dos vídeos del canal K12del MIT con la explicación de la evolución de varios tipos de puente: de viga (beam bridge), de arco (arch bridge), de armadura (truss bridge) y colgantes (suspension bridge). Los vídeos muestran esquemas, la distribución de las cargas, las ventajas y desventajas en cada tipo de puente  así como la curiosa medición de la carga que resisten maquetas de dichos puente. (Nos os perdáis lo que hacen al final con el muñequito de Lego).

Plastics

Hello, in this  unit we are going to study the subject: PLASTICS. Plastics are man-made materials. They are a useful invention because they are waterproof, easy to shape and tough. They have taken the place of traditional materials like wood and metal in many products. It is bad to waste plastic, as it is made from non-renewable resources and takes a very long time to decay.

I post you some links that can be of your interest:

Electricity

We have just started the unit about Electricity. This is a link to an interactive simulatios page about electric circuits. It is in English, but  hope you will undertand it with no problem.

In this page you will be able to review the concepts
