School’s out and you just need something fun to do (besides those piling holiday homework!) Hanging out aimlessly is just so passe, not to mention a waste of your brilliant mind. So, what would be a greater thing to do this holiday than learning up a new science concept to satiate the geek within us? XD

A gear is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part in order to transmit motion (torque). Geared devices can change the speed, magnitude, and direction of a power source.

The gear wheel being turned is called the input gear and the the one it drives is called the output gear.Gears with unequal numbers of teeth alter the speed between the input and out put. This is referred to as the Gear Ratio.

Ask yourself this question, as an individual human being, are you as whole organism, a compound? element? or mixture?

Guess the answer is fairly obvious, yes we are mixtures! Our body is a big soup of blood, body fluids, organs, tissues and cells that are also mixtures of their own.

Most things in this world are mixtures of various compounds and elements.

This concept of elements, compounds and mixture is a topic usually handled at lower secondary level science in the schools. Students often are not so ready to be able to tell how the various substances around them are classified. 

Mixtures are material systems that consist of 2 or more different type of substances blended into each other. The components are not chemically combined. aka no chemical reaction was involved to lead to the formation of the mixture.

On October 25, 2010, the Merapi Mount of Indonesia erupted three times, spewing lava down its southern and southeastern slopes. The eruption took casualties, and still Scientists have warned that pressure building beneath Mount Merapi’s lava dome could trigger its most powerful eruption in years.

But what is a volcano?

A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet.

In simple terms a volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt.
