Agenda

  1. First fifteen minutes: the revision list from yesterday’s checkpoint, worked — Unit 2 Test is next class, and this is the time you get for it
  2. Warm-up: one change, three consequences
  3. Consolidation: one local ecosystem, described completely — biotic, abiotic, energy flow, and one threat
  4. Look ahead: next unit goes inside the matter all of this is made of

Things to do before our next class
