AAAS

  • COMMON THEMES: Scale - Because different properties are not affected to the same degree by changes in scale, large changes in scale typically change the way that things work in physical, biological, or social systems (Full Text of Standard)

  • COMMON THEMES: Scale - Representing large numbers in terms of powers of ten makes it easier to think about them and to compare things that are greatly different (Full Text of Standard)
