PROJECT: PROPORTIONAL REASONING Did you know?
Scale models are often used on movie sets for objects or buildings that would be expensive to build full size. Can you think of a movie where the producers obviously needed scale models during filming?
Scale drawings are used in many fields of study. Many of the applications of scale drawings that you have studied so far use a smaller model to represent something larger. Architects, mapmakers, and movie directors are a few of those who use small models to represent larger objects. These are called reductions.

Scientists also use scale models in many ways. If they wish to represent the universe, then their model is small. But, if they wish to model a cell, then their model is typically 100 times larger than the actual cell size. This is called an enlargement.

Here are your goals for this project:
Draw an enlargement of a comic using a preset scale.
Materials:
White construction paper
Metric ruler
Pencil
A favorite comic strip from a newspaper
Scale drawings are made using a variety of methods. No matter which method is used, the important thing to remember is that a scale drawing should be similar to the actual object. That means that even though the object changes in size, the original shape should remain the same.

You're actually going to draw an enlargement of a comic, using a grid to divide the picture into smaller pieces. Then, you can draw each individual piece into a larger grid. This will ensure that the drawings remain similar.

Read all of the directions and watch the video before starting your enlargement.

Directions:
Choose one frame from the comic strip that you wish to enlarge.
Measure and record the length and width of the frame to the nearest centimeter.
Dimensions of original are ___ cm by ___ cm.
Choose a scale factor so that the enlargement will be at least three times as large as the comic is. State the scale factor you chose and the dimensions of the enlargement.
Scale of original to enlargement is 1:.
Dimensions of enlargement will be by .
This might help!
You'll need to set up two separate proportions to find the length and width of the enlargement.
Frame the large paper by measuring off the dimensions you just calculated for the enlargement and drawing a border. Your enlargement will be drawn inside the border.
Draw 1 cm squares over the comic.
Using the scale factor, draw squares in the frame of the enlargement. For example, if the scale factor is 1:3, then you will draw 3 cm squares on the paper.
Using a pencil, enlarge the comic by using the original as your model and duplicating each square. As you draw, focus only on the square you are drawing at the moment.
Respond to the questions below.
The picture you drew is an enlargement of the original comic. Because you used a scale, your drawing should be similar to the original. The size of the comic should have changed, but the picture itself should have stayed the same.
