Background Information:
Vermiculite is a common material used in the planting of various types of plants. It is said to be efficient in soil aeration, and as a soil medium in germination. Generally it’s PH is 7.0 and varies slightly around the world (Grant, A. 2016). The property of Vermiculite tested in this experiment is soil aeration. This is extremely important for plant growth because if a plant is not aerated well CO2 will accumulate and slow down the growth of the plant (Akmal and Hirasawa, 2004). This would mean that a plants roots would not be able to penetrate the soil and absorb the required nutrients for it to stay healthy. When Vermiculite absorbs H2O it expands creating pockets in the soil allowing for Oxygen to enter the soil (Keay, 1961).
Research Question: What is the effect of Vermiculite (g) on the height (cm) in Mung beans (Vigna Radiata)
Hypothesis:
1. Vigna Radiata with vermiculite will grow taller than Vigna Radiata without vermiculite
2. The null hypothesis is there is no correlation between Vermiculite and height in Vigna Radiata.
Variables:
Independent: Amount of vermiculite in grams
Dependent: Height of vigna radiata in centimeters

As previously stated the groups containing vermiculite grew more or were equal to the group without any vermiculite, all except the last group. The researcher believes that the reason for this is that the plants did not have enough soil to grow strong. Vermiculite is very light weight, but is relatively large in size. When placed in the pots the vermiculite took up a lot of the space, and defeated the purpose of aerating the soil because there wasn’t enough soil. A conclusion can be made that vermiculite can benefit plant growth (cm) as long as there is enough soil for the roots to get
