The scientist concluded that water is the only thing that is responsible for the overall growth of the plant. Whether the conclusion was right or not. Introduction: Jan Baptista Van Helmont conducted the experiment to identify the various sources of raw material for the growth of the plant. Then, he planted a tree with 200 pounds of soil. After 5 years, he concluded that the weight of the plant increases due to the addition of water as the weight of the soil remains same.

Question

About 200 years ago, Jan Baptista van Helmont wanted to know where growing plants get the materials necessary for increases in size. He planted a tree seedling weighing 2.2 kilograms (5 pounds) in a barrel filled with 90 kilograms (200 pounds) of soil and then watered the tree regularly. After five years, the tree had gained almost 75 kilograms (164 pounds), and the soil's weight was unchanged. He incorrectly concluded that the tree had gained all of its additional weight by absorbing water. How did the tree really gain most of its weight?

Imagine you were testing how the presence/absence of soil bacteria affected plant growth. In this experiment you had two treatments - one with soil bacteria present, the other with soil bacteria absent. To determine how soil bacteria affected plant growth, you then measured plant height after 1 month. You find that plants grow taller in the treatment with soil bacteria compared to the treatment with no soil bacteria.

They started to read books, surf the internet and study researches on the effect of music to plant growth, Members from the group continued to formulate their respective hypotheses. They went on performing a simple experiment. The group selected two San Francisco plants of similar size planted on the sanme type of soil and kind of pots. Both plants were healthy. Each plant were placed in separate rooms with a window exposed to full sunlight and were watered with equal amounts every day. They measured the height of the plants. Once a day, they played classical music on room 1 for about one hour while leaving room 2 with no music played. Over a period of two weeks, they noted significant differences in each plant's growth. Multiple Choice: Write the letter of your answer before the number. What was the problem in the Grade 7-Rizal's experiment? Which San Francisco plant is taller?
