Comparing and Scaling PROJECT

This project is due Wednesday, March 4th.

You may choose one of the following options, and you work must be completed neatly and accurately. Write a paragraph explaining the mathematics (ratios and proportions behind your work)

Option 1: Make a scale model of the solar system and use a Ping-Pong ball for the earth. How far away should the sun be? How large a ball will you need to use for the sun? The other planets?

Option 2: Draw a scale map of Berkeley so that it fits nicely onto a standard piece of poster board.

Option 3: Roll a toy car down a ramp, timing the trip with a stop-watch. How fast was the car traveling in miles per hour? If the speed is proportional to the size of the car, how fast would this have been for a real car?
