What to Learn? 
External LinksForcesForces.Learn what forces are and what they can do. Interactive lesson at Skoool.co.uk. What forces do.Learn what forces can do and how to measure them. Interactive lesson at Skoool.co.uk. Effects of ForcesUnbalanced forces.Learn that unbalanced forces change the speed or direction of movement of objects and that balanced forces produce no change in the movement of an object. Interactive lesson at Skoool.co.uk. Balanced forces.Learn that balanced forces produce no change in the movement of an object. Interactive lesson at Skoool.co.uk. Friction.Find out how frictional forces, including air resistance, can affect the motion of an object. Interactive lesson at Skoool.co.uk. Useful friction.Learn how frictional forces can be useful. Interactive lesson at Skoool.co.uk. Gravity and WeightMass, weight and gravity.Learn that the weight of an object on Earth is the result of the gravitational attraction between its mass and that of the Earth, and know that weight is a force so is measured in newtons. Interactive lesson at Skoool.co.uk. Gravity.Learn that gravity is a force of attraction which acts on Earth towards the centre of the planet, and that the size of the force of gravity depends on the mass of each object and the distance between them. Interactive lesson at Skoool.co.uk. Changes of PositionMeasuring speed.Learn how to work out the speed of a moving object and understand how to make calculations using the relationship between speed, distance and time. Interactive lesson at Skoool.co.uk. Measuring speed activity.Play with a simulation that shows the relationship between time, distance and speed. Interactive lesson at Skoool.co.uk. Distance-time graphs.Learn how to plot a distance-time graph and understand what it shows. Interactive lesson at Skoool.co.uk.

That laziness is called inertia. Learn about it. Eureka! - Mass.Learn how the inertia of a body relates to its mass. Effects of ForcesEureka! - Forces and speed.Learn how the force needed to move an object depends on the mass of the object and how much you want to increase its speed. Eureka! - Acceleration (I).That was not quite true. In fact, the force depends on the mass of the object to move and how fast you want to increase its speed. Watch it. Eureka! - Acceleration (II).Let a locomotive driver show to you that acceleration is how much the speed of an object changes every second. Gravity and WeightEureka! - Gravity.Tha gravitational force and Newton's apple. Eureka! - Weight.Learn that you can easily lose weight without diets - you only have to go to the Moon! Theory of gravity tested on the Moon.Drop a hammer and a feather on the Moon, and which one will hit the surface first? Eureka! - Buoyancy.Learn that the buoyancy of an object is the result of a balance between two forces: the weight of the object and the weight of the displaced fluid.

Science Helpdesk is a website meant to help on developing the scientific contents for the Bilingual Project Integrated Curriculum designed by the Spanish Ministerio de Educación y Ciencia and the British Council.
This website is currently under construction. This means that (a) you could spot some relevant errors in the rendering of the pages - please use the "Contact" form below to report to the webmaster, (b) that it is not feature complete, and (c) and that some sections are a bit short of contents - expect it to be more or less finished by june 2009.
This website has been designed and developed by Arturo J. Murias, currently working in the I.E.S. "Francisco Salinas" (Salamanca, Spain) as a Science teacher in the Bilingual Project.
Copyright of the contents belong to their authors, mentioned where known. Contents created by this website author can be freely distributed as long as the source is mentioned.
JavaScript code (and so, every animation and visual effect) has been written upon the terrific jQuery library developed by John Resig and the jQuery team.
