The Circle Lab (Week 1)
Model or Topic Explored: We will be looking at relationships between different measurements of circular objects found at home. We will collect data and present it in several different representations, similar to the lab video. Instructions are provided in the lab video. Please pause the video as necessary to complete each section. We will look at a simple linear model to describe the relationship between the dependent and independent variables. All answers and graphs may be added electronically.

Precautions and caveats: While there are none for this experiment, it is good to note to include this section in future modeling experiments.
Although there are currently no instances for this experiment, it's worth mentioning the importance of incorporating this section in future modeling experiments.

Verbal Model: [Represent the results and the relationships between variables that
you’ve found in words.] I stumbled upon a fascinating connection: the circumference and diameter are intricately linked in a linear and directly proportional manner. The constant value of the slope, reflecting the change in circumference over diameter, happens to be close to pi. I find myself in agreement with the original prediction.
