  Use LaMotte test kits and extra BOD bottles instead of lab protocol. Once samples are fixed, they can be stored in refrigerator for titration later. Expand study to include natural water bodies (lakes, ponds, etc.). Have students conduct a seasonal study of these water bodies. Remember that science lab kits can be used to…

Use house plant if bush beans are not available. Cut plant stems and insert stem into tubing while stem is submerged in a pan of water. This prevents air gaps from forming in xylem vessels. Buy disposable glass pipettes (and reuse). Preparing stem cross section can be optional. Before introducing experiments for biology science fair…

Use fresh pea seeds.   Placing wet, non-germinated peas in vials seems to cause problems with data. To avoid wetting dry peas, determine the mass, volume and hence density of 100 dry seeds (D=M/V). Throw these peas away and then use 25 new, truly dry peas for vial (V=M/D).     Use Teflon plumbing tape…

Use liquid laundry starch or soluble packing pellets in place of soluble starch. Have students tie knots in the dialysis bags instead of using string. Have each group do each solution in order to minimize class data error. Do not use Glucose test tape as it will always test positive in the presence of IKI.…
