Effective model of the cyclical nature of photosynthesis and respiration. This resource highlights that the atoms involved are the same atoms, just rearranged. It is highly engaging and effective for true comprehension. Always a middle school teacher favorite!
Students use (cheap!) pony beads of different colors (representing H, O, and C) and pipe cleaners to build the materials needed for each process. They then put them in a "mitochondria" or "chloroplast" (you can use your imagine for this), and rearrange the beads to make the products. Includes an analysis section. Wonderful way to support NGSS MS LS2-3 and Massachusetts 7MS LS2-3.
