A planet sweeps out equal areas in equal time intervals.
For objects orbiting the same star, the square of the period (T) is proportional to the cube of the semi-major axis (a) (

What is one thing you can conclude from your graph?
How does you graph support/show what you concluded?
What is the science or big idea that support your evidence
Claim: Strong hurricanes start with greatest wind speeds.
Evidence: On the graph the Major Hurricane initial wind speed > Weak hurricane > Tropical storm
Reasoning: Hurricanes are in part rated by their windspeed.
