1. Carbohydrate & Digestion Molecule building activity with model kits.
Build glucose, a monosaccharide. Join with a partner and link to make maltose, a disaccharide. Join with a group to make a polysaccharide. If we had many more groups, we could join them all to build a starch.
2. Digestion. Break apart the polysaccharide into disaccharides and then your original monosaccharide, glucose. Next, model the break-down of glucose through cellular respiration. Break down glucose into CO2 and H2O. You will need to add oxygen molecules (O2). Keep track of how many O2's you add as well as how many CO2's and H2O's are left as products.
