Transcript of 6th Grade Science Fair Project

Problem &
Hypothesis Research Procedure Experiment-DATA Conclusion When a bean is planted, the young stem breaks out of the bean and grows downwards. It is called the main root and after that root, the smaller roots grow. They are called root hairs, or cells. Plant roots grow downwards because they have chemicals that respond to Earth's gravity. Stems have other chemicals in them that grow up away from light. Stems support a plant and carry minerals to every part of the plant. Stems grow from the tip. The outer covering of the bean is the seed coat. The Food supply is called the cotyledons. First. the primary roots grow. Then, the plant breaks through the surface, taking its food supply. Next, the cotyledons from the 1st leaves appears above the ground. After that, the cotyledons store the food for the new plant. Finally, the real leaves of the new plant begin to develop. Plants lose water through tiny holes called stomata. Plants lose their leaves in a process called transportation. Leaves use sunlight to acquire food for the plant. Oxygen is given to plants during photosynthesis. The leaves contain chlorophyll, which makes them green. Flowers have all the parts need to make seeds so a new plant can grow. The fruit is the part of the plant that contains the seeds. A bean is a part of a plant that grows into a new plant. Inside every plant is an embryo with a very tiny root and stem. Embryo is a miniature (small picture) from a plant that is found in seeds. Soil is a mixture of tiny rocks and stones. Soil provides support for plants. It also holds food and water for plants until they need it. In conclusion, our hypothesis was supported by the data.It shows that red beans grew more faster and proper in soil than in paper towel.The paper towel took more time to grow and the soil grew more taller as you can see from my data. From my experiment , I learned how to grow beans in different methods and I also learned that red beans grow faster in soil than paper towel.I think that maybe the amount of sunlight effects how well the plant grows. In soil, bean plants need to be in an area that receives full sunlight, which means eight to 10 hours of sunlight daily. Planting beans in an area that receives six to seven hours of full sunlight daily can reduce the plants' expected yield. Beans do not need sunlight to germinate, but they need warmth. Most beans require a soil temperature of 60 degrees Fahrenheit or higher to germinate well.Planting young bean plants when the sunlight is intense or bright can cause them to wilt and even die. Too much sunlight also can dry out soil, causing the plants to have water stress and blossoms to drop.Along with full sunlight, bean plants need adequate water for proper growth and to be healthy and productive. Soaking the soil to a depth of 1 inch once per week is necessary. The plants also need well-drained soil with a pH of 6 to 7. So, it could be a possibility that most grow faster soil than paper towel. Materials Independent V- the 2 methods of growing

Dependent V- how fast the beans grow Constant- The type of bean,
amount of water and sunlight,
and amount of soil What is the effect of different methods of growing beans on how fast the red beans grow? Project by: Haseena and Aeman
-622 We think that the red beans will grow faster in soil than paper towel, because soil provides support and it also provides water, and nutrients that are vital for plants. Also, decaying plants and animals leave behind minerals in the soil that are essential for future plant growth. 1.
