Potential topic to discuss in science class?

Ross

I believe the answer is:

energy

(Other definitions for energy that I've seen before include "'Vigour, vitality (6)'" , "life" , "Vigour, spirit" , "Go green, possibly with envy, ultimately" , "Seventeen forty six defeat for Bonnie Prince Charlie" .)

I've seen this clue in The New York Times.
