6 Students are using beads of different colors to represent the molecules in food. The beads can be connected in
different arrangements to represent different molecules.
Beads
Chain of beads
What is the best way for the students to use the beads to represent the processes of photosynthesis and
cellular respiration?
Connect all the beads together into the longest chain that can be made.
Combine the beads in chains, take them apart, and then put them together in new chains.
Ο Ο Ο Ο
Take apart all chains and separate the beads by color into groups.
Connect different combinations of beads into chains so that no two are alike.
