29i.e., the leaves may simply droop over the edge of each chamber.Additionally, there need be no lexan ring holding the one half inchmesh of polyester fiber in place.The proposed experiment, as addressed in Mayfield’s paper,only spoke of the mung bean nutrient as a fertilizer. No chemicalcomposition was suggested. However, based on the vigorous growthof the mung bean, water may be employed as long as it has a phsuitable for growth. Any bottled water from a grocery store shouldbe appropriate. Even tap water might be used. The class canexperiment with an altered nutrient solution by adding MiracleGrow, sugar, or other additive to the nutrient solution. Nevertheless,whatever is chosen, it is important to employ the same solution ineach chamber as well as the misting liquid sprayed into chamber six.The vigorous growth of the mung bean during the pregeminationstage requires little or no light so that the limited lightingin the space shuttle crew quarters.Materials:1. Six clear plastic empty 20 oz. soft drink containers2. One of the six containers has a hole drilled in the side nearthe chamber bottom for atomizer insertion and root misting.3. Bandage Gauze from Drug Store4. A pound of mung Beans5. Atomizer for misting the roots of the chamber six plant onceper day6. Clear adhesive tape encircling all six containers so that theyare inline for viewing, photographing and performance of theexperiment7. Scissors8. Adhesive labels, one per chamber9. (Optional) Digital Camera record of daily growing progress.
