How Plants Make Food: Photosynthesis and Respiration Grades 6–8

Where does a tree's mass come from, what happens to the sugar a plant makes, and how does the Sun's energy run a whole ecosystem? Three no-materials lessons with a 400-year-old willow experiment, printed atom cards and a carbon-atom role-play.

• How does energy from the Sun move through a whole ecosystem? 50–60 min

  Every student becomes a carbon atom and travels between four stations, air, plants, animals and decomposers, drawing printed cards that say what happens next. The class tallies the journeys, then follows energy through a food chain, and explains why carbon goes round and round while energy passes through once.
