After studying about recycling, members of Allison’s biology class investigated the effects of various recycled products on plant growth. Allison’s lab group compared the effects of different aged grass compost on bean plants. Because decomposition is necessary for release of nutrients, the group thought that older grass compost would produce taller bean plants. Three flats of bean plants (25 plants/flat) were grown for 5 days. The plants were then fertilized as follows:

1. Flat A: 450g of 2 month old compost

2. Flat B: 450g of 6 month old compost

3. Flat C: 0g compost

The plants received the same amount of sunlight and water each day. At the end of the 30 days the group recorded the height of the plants (cm).
