First,we needed to_.We prepared three pots of bean seeds as the experimental group and one pot as the control group.The_we tested was light-some pots got sunlight,some got only lamp light,and the control group had no light.My group made a_:plants with more light would grow taller and greener.It is necessary for us to prepare the equipment carefully,so we checked the soil moisture and temperature every day. During the two-week experiment,we followed the instructions strictly.Every morning,we measured the height of the plants and_their color changes in a notebook.Not only did we observe the growth carefully,but also we took photos to compare later.Although some plants in the dark started to turn yellow,we didn't give up on recording data. After collecting all the results,we began to_the data.Compared with the control group, the experimental group with sunlight grew 5 cm taller on average.The reason why our hypothesis was correct is that sunlight provides the energy plants need for photosynthesis. What I like most is the moment we drew the conclusion together.In conclusion,this experiment taught me that patience and accurate observation are very important for scientific research.I prefer to do hands-on experiments rather than just read textbooks because they help me understand science better.
