Concept word:

FORCES

  • Physical forces that determine biological form
  • They are invisible but we can infer about them from observation of forms
  • Can be described using mathematical language

Why?

  • Because they are real
  • And affect EVERYTHING inside us and around us
  • Allow us to better understand the world we live in
  • Without this understanding, we would still live in caves
