Name ___________________________ Toilet Paper Scale Model of the Solar System The following table shows the average distances from the sun for each planet. The first measurements are in miles and the second measurements are in astronomical units. An astronomical unit is defined as the distance from the sun to the Earth, which is about 93,000,000 miles. Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto Average Distance from the sun (Millions of miles) 36 67 93 142 484 887 1783 2799 3666 Average Distance from sun (Astronomical Units) 0.39 0.72 1 1.52 5.2 9.5 19.2 30 39 For this activity we will use the scale of one square of toilet paper to equal one astronomical unit (one square : one A.U.) • The sun will be at the beginning of the roll. • Mark the location of each planet according to the scale. Sun Mercury one A.U. Earth When you finish the activity, answer the following questions: 1. What were you surprised to learn about the distances of the planets? Why? _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ 2.
