Identify the IV, DV, Control, and at least two Constants. Suggest a hypothesis for each scenario. After studying about recycling in his new issue of Organic Compost Quarterly, members of Filbert's compost club decided to investigate the effect of various recycled products on plant growth. Filbert's friends finally decided to compare the effect of different aged grass compost on Jalapeno pepper plants. Because decomposition is necessary for release of nutrients, the group hypothesized that older grass compost would produce taller pepper plants. Three flats of pepper plants (25 plants/flat) were grown for 5 days. The plants were then fertilized as follows: Flat A: 450 g of three-month-old compost Flat B: 450 g of six-month-old compost Flat C: 0 g of compost The plants received the same amount of sunlight and water each day. At the end of 30 days the group recorded the height of the plants (cm) and then threw a party featuring Jalapeno peppers stuffed with cream cheese!
