Transfer of Energy
by Simon de Pinna

Review by Alyssa

In this book they talk about all the different types of energy and how they transfer.  Energy is everywhere.  It makes things move and takes many forms. 

You get energy from the food you eat.  Some machines, such as cars or stoves, get their energy from gasoline or natural gas.  Food, such as meat, gives you all the energy you need to keep warm and move around.

Light and energy travel in waves, as do other forms of energy, such as radio waves, infrared and ultra-violet waves and microwaves.  Without light energy we wouldn't be able to see anything.  An object becomes visible only when light from the sun or another source of light, such as a flashlight, bounces off the object and enters our eyes.  When you look out the window, you can see whatever is on the other side, even though there is glass between. 

Transmission takes place when light waves hit a material and continue on through.  Have you noticed that on a sunny day, the dark asphalt gets hotter than the lighter cement curb or sidewalk?  Both are on the direct path of the sun's energy, but the asphalt absorbs more light energy. 

Heat radiation, or infrared radiation, is the form of heat energy that can travel through the vacuum of outer space as electromagnetic waves.  Potential energy is another way of saying "stored energy".

I would like to recommend this book to anybody who wanted to get further knowledge on what are the different types of energy transformations and how they work.  Also the age group I would recommend this to is middle school and high school.
