Be sure to measure from the bottom of the aquarium and not the surface of the potting soil. Each group had there own task of making sure that the plants were always water, each plant had the same amount of light on them. The plant may not appear healthy and its leaves, flowers and fruit may look wilted or shriveled. The most valuable resources for teachers and students. Trials: Sarah is going to test ten pots with the same amount of soil , and place ten mung beans in each pot. Watering a plant with salt water also impedes the amount of water the plant can absorb. The Dependent Variable was the length of the plant/ how tall it grew. Measure from ground up to the tallest part of the plant. Materials: radish seeds (one packages will be enough for multiple experiments), water, paper towels, plastic beverage cups, aluminum foil, liquid fertilizer (plant food purchased from the grocery or home supply store). This experiment examines the rate of plant growth when watered with different solutions. Review each step of the procedure to find sources of potential errors.
If soil does become very dry and hard to rewet, use the double watering method. The plants we were testing were radishes We decided on testing the
You usually want to know in advance if there will be a response to added fertilizer so that you can avoid growing plants under nutrient-deficient conditions. 3. Jean Paolo Paglicawan
This project guide contains information that you need in order to start your project. The plants absorb carbon dioxide through the stoma of the leaves. Plant 3, which was placed in a cabinet, only grew 2 cm. If amount of water traspired by a plant, in a given time, exceeds the amount of water absorved; it will lead to wilting of plant and the rate of transpiration will be reduced. The dynamo theory suggests a mechanism through which a celestial body, such as a planet or a star, can generate a magnetic field. How does the amount of water affect plant growth? 1
Observation/Research: She water them every day, they have good soil, and they're in the shade. Label one of the cups as a control and label the others with numbers from 1 to 9 . It also has a significant effect on the organic materials that are able to survive in the soil as well as how things like pesticides, metals, … Water evaporates rapidly from the sides of a porous clay pot, which requires more frequent watering than nonporous, glazed or plastic pots. However, fertilization with these nutrients is not usually necessary because the Ca and Mg contents of soil are generally sufficient for most plant species. In addition, the amount of fruit the plant produces increases. This strategy is now used for agricultural development in Israel. What was average growth of plants with regular water and average growth of plants with salt. The problem you'll attempt to solve while doing this science fair project is whether the pH of the water with which plants are sprinkled affects the rate of growth. 2) The experiment can be enhanced by including various brands of fertilizers available in the market to find which fertilizer works best for plants. Sulfur is usually present in sufficient quantities from the slow decomposition of soil organic matter, an important reason for not throwing out grass clippings and leaves. It was determined that the plants watered with 400 milliliters of water once a day showed more growth. To get a better idea of what you'll be doing, and to help you formulate a hypothesis, it's important that you have a … By receiving it, a plant is able to convert sunlight into edible food that it can use. If you need a control, get an additional small pot in which you plant a bean seed, but you don’t water it at all. The greater the amount of water, the faster the growth. What conclusion could you draw if you had performed the experiment with only one cup? Investigate the growth of three common garden plants: tomatoes, beans, and turnips. The rule-of-thumb is to water when necessary. 1) Why did you need 10 cups to perform this experiment? 2. Roots need both water and oxygen, and when surrounded by water, they cannot take up oxygen. TABLE OF CONTENTS
Each time the pot number 1 will get the least amount of water and the pot number 6 will get the most. http://collaboratory.nunet.net/timber/scifair/kindto4/8.htm, http://jajhs.kana.k12.wv.us/jahome/fro/project99/campbell.ht. Once the seeds have germinated, remove the foil and place the cups in a location that provides them with light. At this level, science becomes even more interesting and powerful. Observe the effect of each variable on plant height, plant mass, leaf color and leaf size. Change in type of water could have affected the plant growth. One represents the least amount of water and 9 represents the highest amount of water. Place the aquarium in direct sunlight. Use blue, yellow, and red film for the other filters. Determine what conditions produce the tallest and healthiest plants. You may need to calculate the average heights of seedlings in each paper towel. However, too much water can result in root rot. A suggested approach to fertilization involves the following steps: The best way of knowing what your plants need is by observing plant performance and understanding the multiple factors affecting such performance (e.g., light, water, temperature, pests, nutrition). Empty the saucer. ...The Effect of Gray Water on the Growth of a Mongo Plant
So she decided to experiment on what is the effect of watering on plant growth.
Each day add 10 drops of water to cup number 1, 20 drops of water to cup number 2, 30 drops of water to cup number 3 and continue with the same increment so the cup number 9 will get 90 drops of water each day. According to Gardening Know How, water can affect plant growth both positively and negatively. It was between 9-11 ml. Statefields School Inc.
Organic matter (such as grass clippings, tree leaves, shrubbery and tree trimmings) is an excellent source of plant nutrients. Details of this project More details or support for this project is available for the members of ScienceProject.com. Plants need 18 elements for proper growth and reproduction. Touch the soil – The most accurate gauge is to water when the potting mixture feels dry to the touch. I. With a basic understanding of these factors, you may be able to manipulate plants to meet your needs, whether for increased leaf, flower, or fruit production. plant C? The water temperature should be between 62 and 72 °F. Each one is potted in the same type of soil and receives the same amount of sunlight and water each day.
If you did not observe anything different than what happened with your control, the variable you changed may not affect the system you are investigating. To do that, you would need to use extremely hot or cold water, and as we mentioned, that would put the plant under stress; and in any case, a quarter of an hour later, the temperature in the substrate would be back to what it was before watering. This experiment was conducted to determine whether or not those plants can grow in low fertilized, less sun light and the control group. A student conducts an experiment to see how music affects plant growth. Experimental Design:
Formulate a Hypothesis: Sarah think plants will grow better if they're in the sun, than in the shade. Stated simply, you need to fertilize whenever you expect to get a desired plant response. Different types of waters contain a variety of chemicals and minerals, some helpful while others harmful to plants. When plants receive the right type and correct amount of water, they flourish. Read books, magazines or ask professionals who might know in order to learn about the effect or area of study.
Based on these trends, we can draw conclusions about the system under study. followed by one of the following measurement: 20 ml, 40 ml, 60 ml, 80 ml or 100 ml of water. Introduction
The readings can be influenced by factors other than soil moisture content. Do not water plant B. Keep track of where you got your information from. Plants are called autotrophs; meaning that they create their own food source.
An Investigatory Project
Does Microwave Radiation Affect Plant Growth? Now is the time to pull together what happened, and assess the experiments you did. The factors are displayed in the diagram below. Is your hypothesis correct? Materials Used
This can be in the form of a table of processed numerical data, or graphs. Caffeine can be introduced to the soil by sprinkling grounded coffee over the soil, adding leftover coffee to the pot or watering with a caffeine solution made by dissolving a caffeine tablet in water. Therefore Miracle-Gro™ is the best water type to use when growing plants. Variables
