Agenda

  1. Investigation: Measuring a Gas Law — volume against pressure, then heat
  2. Plot as you go, in pencil — the shape matters more than the points do
  3. Compare shapes across the room: one curve, one straight line, and why
  4. Say in words what each graph claims, before any law is given a name
  5. Safety in practice: gas is never trapped in a rigid sealed container

Things to do before our next class

  • Finish both graphs with labelled axes and units.
  • Journal: describe each relationship in a sentence, without symbols.
