Read the description about an experiment conducted and identify the following partsof scientific method. (30 pts)A farmer wanted to investigate whether a bamboo palm plant grow better inside or outside. Hisinitial thought was that there will be no difference between the growth in indoor or outdoor. Hedecided to plant ten plants in identical pots using same type and same amount of soil. Then heplaced five of them in outdoor location and the other five in an indoor location. The outdoorplants were receiving same amount of sunlight and both indoor and outdoor plants were givensame amount of water. Each day for three weeks the plant growth was observed and measuredby recording the size of each plant. It was observed that the indoor plants had grown more insize than the outdoor plants.Question of Interest:Hypothesis: 21. a. A liquid has a volume of 10.95 mL and a mass of 75 g.
