Steps of Scaling

• Pick a scale you want to use to build a model.
• Make a table of the dimensions to be used in your
  model from the dimensions of the object
• Build your model using the dimensions calculated
  in step two

The Statue of Liberty

• The Statue of Liberty has the following
  measurements. Copy these on a sheet of paper.

Choosing a Scale

• The first step of making a scale model is
  deciding what type of scale to use. Today you
  will be using a scale of
• 1 inch 35 feet
• The next step is to create a quick table of the
  dimensions of your model at the scale chosen.

Calculating Model Dimensions

• To calculate model dimensions take the actual
  dimensions of the object and multiply it by the
  scale being used. Today we will neglect the
  inches used in dimensions (so 305 1 will just
  be 305) and we will round off our model to the
  nearest ¼ inch in each calculation.
• For example,

Actual length of right arm 42 feet 42 feet
Round to the nearest ¼ inch to get 1.25
inches as the dimension for our model.
1 inch _ 35 feet
X
1.2 inches

Create Your own Table

• Now create your own table with all the
  dimensions you will use for your model. Heres
  how it should look with the one we already did
  filled in.

Basis for Your Model

• To help with building your model you can draw a
  rough sketch of what you want your model to look
  like with dimensions drawn in. This will help
  when you are building your model to help you
  remember what size everything is.

Start Building

• The final step is to build the model. Now sculpt
  the Statue of Liberty according to the dimensions
  you calculated.

Questions

• If the scale was 1 inch 17 feet, what would the
  dimensions of the model be?
• If the scale was 1 inch 10 feet, what would the
  dimensions of the model be?

• Sarah,
• Thanks for sending me the scaling activity. And
  thanks for the explanation about how the process
  works. )
• I use the ideas for the scaling activity in class
  this week. One day the students drew
  two-dimensional drawings of how to get from home
  to school, use the scale on a map to figure
  distances, measured and drew a scale model of the
  classroom, etc.
• The next day we went through the powerpoint
  presentation that was included in the email. I
  learned how to use some new technology (hooking a
  projector up to my computer), and the kids seemed
  to enjoy a change of pace with how the notes were
  presented. Then the students built the model of
  the Statue of Liberty using "Fun Dough" that I
  had purchased at Wal-Mart that morning (at 0.97
  for a four pack). They worked in partners.
  There wasn't quite enough dough for the whole
  statue, so they had to use the cannister for part
  of the base of the statue!
• Thanks so much for the work. It turned out to
  come at a good time after all!
