Research Question - What is the relationship between the radius of a paper circle and the mass of that circle?
DESIGN |
|
Independent Variable RADIUS of the circle
Dependent Variable MASS of the circle
Controls Material of the circles, the scale used, and the ruler used to measure the radius
The Controlling Variables
We decided to use the circles that are made of the same type of paper/material. We used the same scale to measure the radius of the circle, so we can minimize the error caused by different scales of the rulers. We also used the same scale to measure the mass of the circles.
The Procedures
#1 Randomly draw circles with different radius and cut them out
#2 Measure the radius of a circle using a ruler
#3 Weigh the mass of a circle using a scale
#4 Repeat #2 and #3 until all the circles are measured in radius and weighed in mass
