Warm-up: where does a tree come from
Ask them where a tree's mass comes from before you tell them anything. Most of the room will say the soil, and a few will say water. Let the wrong answers sit there for a moment. Then say it: almost all of it came out of the air. That sentence is the whole lesson, and everything after it is evidence.
The two stages
must coverSay any one of:Calvin cyclelight reactions
Light reactions capture energy and split water. The Calvin cycle uses that energy to build sugar out of carbon dioxide. Say both names out loud, because they will see them again on every exam they ever sit, and the names are the part they forget first.
Draw it
Board time. Sun, leaf, arrow in, arrow out. Keep it ugly and fast. Ask someone to label the arrow that carries the carbon.
Why anyone should care
must coverNearly every atom of oxygen you have ever breathed came out of this reaction, and nearly every calorie you have ever eaten was assembled by it. Marked must-cover with no anchor phrase, because this is the part worth saying in full, in whatever words the day gives you.
Where it breaks
The honest edges, if there is time. Night. Drought. Why leaves change color. Not on the exam, and the reason half of them stay after class.
Exit ticket
must coverSay any one of:one sentencebefore you go
One sentence on where a tree's mass comes from. Collect them at the door.
