Part A

Day 1

1. Using the marking pen and the labeling tape, label one clear plastic cup "Soil Cultivated," and label the other plastic cup "Hydroponically Cultivated."

2. Fill the cup labeled "Soil Cultivated" halfway with moist potting soil. Place six wheat seeds on the surface of the soil; use the distance between the holes in the foam floater as a guide to determine the spacing of the wheat seeds. (Do not place the floater on the soil.)

3. Press the seeds into the soil until they are approximately 0.5 cm below the surface. Cover the seeds with soil, and press down firmly.

4. Water the seeds with 10 mL of distilled water.

5. Add 50 mL of complete nutrient solution to the cup labeled "Hydroponically Cultivated," and place the plastic-foam floater on the surface of the solution, as shown in the figure below.

6. Place the cheesecloth on top of the floater, as illustrated in the figure. Press lightly at the location of the holes in the floater to moisten the cheesecloth.

7. Place the remaining six wheat seeds on top of the cheesecloth in the cup labeled "Hydroponically Cultivated." Position the seeds so that each one lies in an indentation formed by the cheesecloth in a hole in the floater. Press each seed lightly into the hole until the seed coat is moistened.

8. Place both cups in a warm, dry location. Water the soil-cultivated seeds as needed, monitoring the amount of water added. Aerate the roots of the hydro-ponic plants every day by using a clean plastic dropper to blow air into the nutrient solution.

9. In your lab report, prepare data tables similar to Table A and Table B. Write your observations of the seeds in your data tables.
