Caroline van Bommel 23-04-2002 Group 4: Chemistry Lab Title: Rates of respiration in crest plants, which are grown in different soils with a different pH Aim: To measure the rate of respiration in Crest seeds which were embedded in different soils. Hypothesis: I think that the seeds, which are embedded in the soil sample with the most neutral pH, will show to have the highest rate of respiration. Variables: Control- amount of water added, the amount of soil, the amount of Crest seeds, the temperature of the soil and the duration of the experiment Independent- the area where the soil sample is from. Dependant- the amount of O2 consumption. Materials: For part 1 of the experiment Glass filter 100 mL Erlenmeyer flask For part 2 of the experiment Erlenmeyer flask 250 mL 100 mL beaker 10g of soil (either forest, moss, or potting soil) 10 ml KOH 1.0 mol 3 Cotton balls 3 x 100 Crest seeds 3 x 8 mL of distilled water 3 Wooden corks Wool...
