Learning Planet Sizes
Student Self Assessment Rubric

As a result of the activities in this project I learned :
Compare the size of one student with another <  =  >.       
Compare the size of the earth to one other planet <  =  >.       
Give three or more examples of scale models.       
Order three (or five or nine) planets in size from largest to smallest.  (Select one number for success.)       
Measure the size of classroom objects using different kinds of units.       
Measure the circumference of balls using different kinds of units.      
Select a ball to be a scale model of the earth, then select other balls to represent the other planets.       
Build "scale models" of planets using different materials.
