When architects and draftsmen design plans for construction projects, they make two and three-dimensional models that are used for reference when the actual construction begins. The measurements of objects in a scale model are proportional to the measurements of the actual object. For example, if the height of the actual object is to be twice its width, then the height of the scale model will be twice its width.
In order for a scale model to be accurate, the same proportion, also called the scale, must be used. If the scale is 1/4 in. = 1 in., for instance, every measurement in the model represents one-fourth of the actual measurement. Therefore, a measurement if 12 inches on the model would represent 48 inches, or 4 feet, in actuality.
Your project is to create a two-dimensional scale drawing of a room in your home. Begin by measuring the dimensions (length and width) of the room that you have chosen. Using these measurements, decide what scale you will use so that the drawing will fit on the paper. Most rooms are not perfectly square or rectangular, so make sure your drawing depicts the actual shape of the room. Once you have drawn the dimensions of the room, you need to add the details. If you chose your bedroom for example, include the placement of your bed, dresser, closet door, stereo, TV etc. all drawn to scale. Make sure to write the scale you use on your drawing.
* Be as precise as possible with your measurements and as always, be neat. Be sure to label all of the objects in the room. *
Things to remember:
*Label the objects in the room
*The scale (on the drawing)
*The objects in the room (minimum of 5 objects)
*Accuracy is very important
*(Do not use pen
*Include all calculations (Show all work) on separate notebook paper
*Do not put your scale drawing on notebook paper
