The proposal research aims at determining whether plants grow well in water or soil, when carried out practical through setting up an experiment. The information obtained from this experiment will help gardeners have knowledge on how to grow their plants healthier, taller and faster.
Basing my research on the science books I used while carrying out the research, it shows that vegetables will relatively do well in water, the flowers will grow better in soil and grass will grow equally better in both. During the research period, the information I found from the science books and encyclopedias showed the same results on hydroponics.
Same kinds of seeds
Same amount and kind of water
Same kind of kind and size of containers used
The displaying difference was growing the plants in water or soil.
The expected out come results were the difference in plant’s mass when measured in milligrams using beam balance and their total length measured in millimeters using a ruler.
Lawn grass seeds
Batcher’s button seeds
During the research I found out that most scientists used the above mention seeds while carrying out their experiment because their growth is negatively affected by changes in environment and shows clear variation in their growth in water and soil. In this case I also decided to use these kinds of seeds for effective results.
1. Collect all materials to begin the experiment
2. Place soil to about 6cm high in 5 plastic containers
3. To the other 5 containers place white purified sand to the same height
4. Take 4 cucumber seeds and place them in one of the soil containers and 4 seeds in one of the sand containers, and label them “cucumbers”
5. Place 4 snapdragon seeds in one of the soil- filled container and 4 seeds in sand container, label it “snapdragons”
6. Place 4 radish seeds in another container filled with soil and 4 seeds in sand-filled container label it “radishes”
7. Place 4 batcher’s button seeds in another soil-filled container and 4 seeds to sand filled container and label it as “batcher’s button”
8. To the last container, place 4 grass seeds in one of the soil-filled container and 40 seeds in one of the sand filled container and label as “grass”
9. Being careful not to stir up sand and seeds, pour 100 ml of water in the sand-filled container.
10. Soil-filled plants should be watered with 40ml of water everyday
11. After 4weeks record their growth and keep the data records
12. Measure their mass and length on the 28th day.
For accuracy in their weight plants should be dirt off.
The results of the experiment are as shown below graphically.
Water being an essential need to living organism is more so to plants. In this way plants can obtain water from rain or being watered by human being.
Soil also is of high importance to plants. This is because they provide plants with special nutrients that helps the plant to grow bigger and faster. It also anchors or gives support to the plant by covering their roots whereby some plants breathe and take in nutrients through their roots.
Hydroponics being the artificial way to grow plants became a scientific fact once other scientist proved it could be done, though sand is place at the bottom to act as soil and help roots.
Plants grow all over and some are used for food while others beautify the environment. In the experiment, radishes and cucumber represents food, while snapdragon and batcher’s are example of flowers, and lawn grass representing grass.
I hereby conclude that flowers grew better in soil, vegetables did well in water and grass would grow relatively well in both. At the end of the experiment I summarized that plants can grow in water instead of soil, and still serve the purpose.
