More Accurate - Team A
Estimations are not good enough for Sarah and Max. They want to know how diameter and circumference are connected!
Thankfully you can help with Simulation Circle:
Change the diameter of the disc in the animation in the left pane by pulling the red slider.
When you pull the black slider, the disc unrolls.
Doing so you can find out how the circumference changes with the diameter.
Circle
Now increase the diameter step by step from 0 cm to 8 cm, unroll the disc and observe how the circumference changes. Take notes of your initial observations.
These are the diameters of the six wooden discs on your table:
Check your estimations for task 1 and 2 with the aid of the simulation!Disc No. Diameter 1 5 cm 2 5,5 cm 3 6 cm 4 7 cm 5 7,5 cm 6 8,5 cm
Not all diameters of the wooden discs appear in the simulation. Describe how you determined the corresponding circumference of these.
Max and Sarah both observed the changes in diameter and circumference closely while you worked with the simulation. They are sure, there has to be a correlation!
Which variable did you alter in the simulation and what happened with the other variable?
Sarah says: "Oh, now I see it. Every time we increase the diameter by 1cm, ..." Help her and complete the sentence.
