| Abstract | I wanted to demonstrate that plants can grow in many ground types. To |
| prove my demonstration I planted green onions in sand, soil, pebbles, |
| and just water. I also wanted to test which type would produce the most |
| amount of growth. To do this, I measured the change in height. |
| |
| The data I needed to prove my demonstration was the growth of each |
| plant from each type of ground type. I need to measure each green |
| onion from where they were cut and the growth before they where |
| planted and after they where planted. |
| |
| I noticed that the green onions that were planted in the sand had the |
| highest growth. The highest growth of the sand was 23.5, highest for |
| soil was 23, the highest for pebbles was 11.8 , and the highest for just |
| water was 10.8. I planted three green onions in every soil type to |
| ensure that my results were valid. From my results, I concluded that |
| the sand provided the best growing conditions for the green onions. |
