The purpose of this project was to determine how much the amount of water effected plant growth. This had been accomplished by taking three groups of plants and placing them next to one another. Each group contains two plants. Each one would be watered with a different amount of water. They would then be measured how much they grew. The growth of the three plants was compared.

Hypothesis: If the plants receive more water, then they will grow faster.

Introduction

The idea of how the amount of water affects plant growth had come when a student looked out the window longing for freedom from class and say how the rain watered the plants and an idea was born.

This project topic was chosen because we often hear the theory that plants need lots of water to grow fast. This experiment was done just to make sure this is true.

The purpose of this project was to determine how much does the amount of water a plant receives reflect of the size of its growth.

Method

The test subjects used were The plants were obtained from
The apparatus’s that were used were identical pots, soil, and type of water. A measuring cup was used to measure out the needed amount of water. A ruler was used to measure the height of the plants.The dependent variable was measured with a ruler from walmart. The independent variable was measured by a measuring cup from the kitchen of Jason’s mother. The control was the amount of soil in each pot was the same. Also all of the pots used were the same.
