The Good Place … for Beans

In this project we test how different conditions affect the growth of beans. We have a control group, which is supposed to show us the regular growth of a bean in soil that is watered just by water. We have four different experiment conditions for the beans. In the first experiment, we watered the soil with sugary water. In the second, we watered the soil with both water and milk. In the third experiment, we put tea in the soil and watered the soil only with water. In the fourth, we put beans in a jar full of mosses, and watered them with water. Unlike our expectations, the sugar didn’t stimulate the growth of beans but created a better environment for other organisms to develop, and the bean began to decompose. Milk, which we chose because of its components calcium and sugar (lactose), didn’t help beans either; on the contrary, it stimulated the growth of mold. The situation changed when we added tea. The tea, acting as a fertilizer, created a good environment for the beans to live in, resulting in the growth of roots, leaves, and beanstalks. The nettle, the caraway and the coriander in the tea contain calcium, potassium, magnesium, vitamin C, B, and E, amino acids, beta-carotene, fibers, phytonutrients, iron, zink, calcium and fiber. As the results state, all of these minerals helped the beans grow, creating a rich in nutrients environment. Beans were also prosperous among moss. Since moss doesn’t absorb nutrients from the soil, the beans lived and grew unaffected; the moss also kept their jar humid. In conclusion, moss and tea acting as a fertilizer created the best environment for beans to live in.
