Introduction

Our activity will be about where plants grow faster in cotton or soil. Plants bring to us oxygen, vegetables, fruits, nuts, medicinal herbs, green cover for earth, etc. These are some of the reasons why we should know everything about them. It´s interesting to know how we can make them or help them grow faster so we can provide their products. In the research we are planning to try different growing locations. We are trying in 2 different growing methods: planting our beans in cotton and the other bean will be planted in soil, as natural growth. We will take notes about the developing of the experiment.

Hypothesis:

Plants need nutrients to be able to grow. In this case we are going to plant a bean plant. Cotton balls don't have any of the nutrients that plants need to grow, in comparison with soil. The plant can still fix nitrogen and carbon from the atmosphere, but there're some vital minerals and other essentials that are missing in cotton balls. And it all depends on the amount of nutrients you are able to feed through to your plant. Usually, you should use soil for your plants. However providing the required nutrients is necessary. We think the plant will grow faster in soil because it will be receiving all the nutrients it needs. Maybe the cotton plant will not die, but we are expecting to see differences in the growth and development of both of the plants.

Method and Materials

• Method:

We are going to have two plastic containers, the first one with cotton balls and the bean. The second container will contain soil and the bean. They’re both in the same outside temperature and they will both receive the same amount of water and sunlight. The only variable will be the area in which they are grown.

• Materials:

- 2 plastic containers

- 2 beans

- Cotton balls

- Soil

- Water

Results

The original purpose of this experiment was to determinate whether plants grew better in water or soil.

The result of the experiment where that our little beans grew faster in the soil. We realize that the soil provides plants with special nutrients that help the plants grow faster and bigger. The soil also helps the plants grow in another way, it covers the roots. You may plant the seed in the dirt, but the stem grows up and out of the soil. But the plant would die if the root ere not covered. Plants “eat” through their
