Caffeine and plant growth Do not water with hot or cold water. Their plants aren’t grow . Background of the... ... 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. Ms. Ailene Hijara Some plants seem to benefit and grow faster when caffeine is added to the soil, while others seem to become stunted or grow slower. Thus, a “good” response to fertilization under one set of circumstances may be a “bad” response under another set. ...The Effect of Gray Water on the Growth of a Mongo Plant The student obtains four identical plants. Therefore Miracle-Gro™ is the best water type to use when growing plants. Write a statement that describes what you want to do. This process is called photosynthesis. Description Allow the pot to drain completely. 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 … What affect does the brightness of light have on the growth rate of a plant? In this experiment, 8 plants will be tested. followed by one of the following measurement: 20 ml, 40 ml, 60 ml, 80 ml or 100 ml of water. Upon decomposition, those nutrients in the organic material become available for reuse. We should note here that the plant responses we get from applying fertilizer and other soil amendments are not inherently “good” or “bad.” These terms are subjective and reflect personal judgment as to what is “desirable.” For example, a greater quantity of fruit which is too small for market is not a characteristic desired by a peach farmer. In order to test how does the amount of water affect the plant growth, we plant some seeds and use them to test the effect of water. Repeat with the above steps ten times until you have ten rolled paper towel with 6 seeds in each of them. Place the aquarium in direct sunlight. Recommendation Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition. You may still have to supplement, but you will then apply fewer nutrients–and a lot less fertilizer. We felt the magic immediately.". However, too much water can result in root rot. Many questions are related. As such, it displays different properties depending on its wavelength. The Dependent Variable was the length of the plant/ how tall it grew. Question. n conclusion, the experiment was about the effect of soapy water on plants. Acidity heavily influences absorption and solubility which is really important for plant growth. Overview It is the easiest, least expensive, and most environmentally sound way to fertilize. The primary needs of plants include sunlight, air, water and soil. The purpose of the lab was to record and notice the growth of the plants from all the different variation, like the low fertilizer, control, shaded group. Plants require water, but not everyone realizes that overwatering can be as damaging to a plant as too little water. The grounded coffee is actually organic matter and will help in adding nutrients to the soil. Once the seeds have germinated, remove the foil and place the cups in a location that provides them with light. However, too much water can result in root rot. However, does the soapy water negatively affect the plant’s growth and development. During these periods and while it is dormant, a plant will need less water. Gabriel Joshua Palma In this project we will study the effect of pH on plant growth. The Dependent variable is the height of the plant. It depends on what response the person wants from the plant. Rap the side of the pot with the knuckles or a stick. Question Does the amount of salt added to the water that plants are watered with effect plant growth? Plants need 18 elements for proper growth and reproduction. You can change the amount of light each plant gets, the amount of water added each day, and the type of soil the seed is planted in. What conclusion could you draw if you had performed the experiment with only one cup? 7.... ...Effec | Effect of caffeine on plant growth | If the sound is dull, the soil is moist; if the sound is hollow, water is needed. Some of the seeds wouldn’t grow fully, they will just freeze the growing and eventually stop evolving. I. 2) Label each pot with numbers from 1 to 6. Roots need both water and oxygen, and when surrounded by water, they cannot take up oxygen. What happened to the color of plant A? In this project we will try to see how the amount of water affects the plant growth. CHEMISTRY 6 answers. Plant … Other plant-essential nutrients used in fairly large quantities are calcium (Ca), magnesium (Mg), and sulfur (S). The water temperature should be between 62 and 72 °F. This experiment examines the rate of plant growth when watered with different solutions. 2. For centuries plants grew without any help from human beings, and many are doing so today. Place a piece of aluminum foil loosely over all four cups and allow the cups to remain undisturbed until the seeds germinate (2 to 4 days). These elements are sometimes called minor elements or trace elements, but use of the term micronutrient is encouraged by the American Society of Agronomy and the Soil Science Society of America. Without light, photosynthesis does not work properly and therefore the plant does not get enough food. The Keep track of where you got your information from. The researchers lovingly dedicated this Investigatory Project to their respective parents who have been their constant source of inspiration. Plants can grow in deserts, rain forests, and even in your own backyard. Problem/Question: Sarah observes the small garden in their house. Also make sure for the plants that need Miracle-Grow get their daily amount of Miracle-Grow when needed. Table of Contents This experiment showed that watering plants with any amount of salt water inhibits the growth and life of a plant by dehydrating it. Use your observations and questions to write the statement. Water once and then again half an hour later; or place the pot in a sink or a bucket of water. Identifying variables is necessary before you can make a hypothesis. [ [ Plant A listens to classical music for three hours each day. Water temperature has a direct effect on the growth of aquatic plants. It is only in certain environments and growing conditions that one or more of the nutrients are deficient. 2) What effect did the amount of water have on the plant growth? If there are more negative ions in the water, the liquid is more basic. These variables are the factors in the experiment. Judge soil color – Potting mixtures will change from a dark to lighter color as they dry. Water plant A every other day, keeping the soil moist but not wet. The recommended Often, mathematical equations can be made from graphs. The Earth possesses such an electrically conducting fluid (liquid iron) in its oute… Question: How do various liquids {tap water, river water, salt water, carbonated water, and soda} effect plant growth? Record the results of your experiment 1 in tables like this: This table shows the average height of seedlings in each cup in different days starting day 4. So, why do we apply fertilizer to the soil? Observe the effect of each variable on plant height, plant mass, leaf color and leaf size. Hypothesis…………………………………………………………………………..6 Radish seeds (one packages will be enough for multiple experiments), Samples of liquid fertilizers (plant food purchased from the grocery or home supply store). You are keeping valuable materials on site and are also greatly reducing the municipal solid wastes placed at curb side. The Effects Different Types of Water Have on Plant Growth Add the necessary nutrients to one gallon of water that will be used for our experiment. First, a plant's growth is stifled. Plants also need water for cellular function. A large plant in a small pot needs water more often than a small plant in a large pot. Is your hypothesis correct? Since predicting plant responses is difficult, many people apply fertilizer as insurance against nutrient deficiencies. A student conducts an experiment to see how music affects plant growth. Because it does, it has some of the same needs as other green plants--sunlight, carbon dioxide and water. 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). the best plant growth (yield) in both length and weight categories, is that of Miracle-Gro™. In this experiment, you'll control the pH of the water you'll use on bean plants by adding certain substances to make distilled water either acidic or basic. I used two seeds in each bag to make sure if one seed wasn’t good, the other one would grow. There is no magical way of knowing which nutrient may be in limited supply in the soil. Hypothesis . It will also attract worms that feed on the grounded coffee and at the same time help to aerate the soil. Controlled variables are light and temperature. The readings can be influenced by factors other than soil moisture content. Each plant will receive 1 more teaspoon than the previous cup, so it would be increasing. It is important to understand how these factors affect plant growth and development. These equations allow us to predict how a change will affect the system without the need to do additional experiments. Results showed that filtered water was best for plant growth with bottled water coming second, while distilled; tap and flavoured water were not the most successful. Plant B listens to rock music for three hours each day. Does Microwave Radiation Affect Plant Growth? As a result of habit, all three are still applied even though there are now many situations, especially in gardens and landscapes, where plants do not respond to one or more of these fertilizer nutrients. Review of Related Literature Independent variable : The independent variable in this science fair project is the amount of water used every day– 20ml, 40ml, 60ml, 80ml and 100ml once a day or twice a day. The water started metabolic (growth) activities within the seeds that produced enough energy for plant growth. The experiment was done by using mung bean plants and watering them daily with water, water mixed with caffeine and with a coffee mixture. Materials: Greenhouse or sunny window sill, 10 bean seeds, 10 small pots, water, ruler, potting soil, pencil. Definitions of Terms…………………………………………………………….5 The solution for the recommended amount of Miracle Grow for pot #2 was (It is interesting to think that germination can occur in almost complete darkness.) plant growth. Some plants thrive under moist conditions while other plants grow well when kept drier. However, the difficulty is in predicting. Experimental Design: In addition to the basics, you can help plants grow even larger by adding extra nutrients to the water. At this level, science becomes even more interesting and powerful. Testing was done using hydrilla plants in water with and without a layer of oil covering the surface. 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. This is because the roots of your plants are very sensitive to extremes of temperature. It is important to understand how these factors affect plant growth and development. If you determine that experimental errors are influencing your results, carefully rethink the design of your experiments. The Independent variable of this experiment is the light that enter the plant. (1981) made a comparative study to of response of major crops to Remove it and gently wring out the excess water. Thus, it is obvious that they can do so by themselves, especially in environments to which they are adapted. The hypothesis that plant growth increases as the amount of sunlight increases was supported by the data. Methods/Procedures…………………………………………………………..7 I called School Time and my husband and son came with me for the tour. Micronutrients are those elements essential for plant growth which are needed in only very small (micro) quantities . Investigate the growth of three common garden plants: tomatoes, beans, and turnips. 1) Why did you need 10 cups to perform this experiment? Details of this project More details or support for this project is available for the members of ScienceProject.com. The plants absorb carbon dioxide through the stoma of the leaves. One filter should be clear. Problem Statement Procedure: Fill the 10 small pots with equal amounts of dampened potting soil. The plant may look dry and the leaves brown. It is from calculations using recorded data that tables and graphs are made. Plant A listens to classical music for three hours each day. ... Empty the saucer. Make sure each day each plant gets the same amount of water throughout the experiment. Hypothesis: However some other sources suggest that it could harm the plant and that normal clean water should also be used. What About Organic Matter as a Source of Nutrients? If peat is allowed to dry completely, not only is it difficult to rewet, it also will not hold as much water as it could hold before it dried. A student conducts an experiment to see how music affects plant growth. The result: over fertilization in the United States is now as prevalent a problem as under fertilization. 15.2 Experiment Design Plant growth is affected by several factors such as seed variety, amount of water, soil type, amount of light, temperature, humidity, and other. Presented to: Plant A grew 13.6 cm while Plant B grew only 5.2 cm. The Control variables are the amount of water given and the amount of sunshine. There is a wide range of watering requirements for different species of plants. The plant may not appear healthy and its leaves, flowers and fruit may look wilted or shriveled. Hypothesis 4) Make daily observations and record the height of you plant every day for two to three weeks. #3 was 2 scoops of powder and 2 liters of water. Observe the effect of each variable on plant height, plant mass, leaf color and leaf size. A plant in a warm, dry, sunny location needs more frequent watering than one in a cool, low-light environment. Hypothesis: Legoman predicted that the plant that was given the river water would grow the most. and double the recommended amount of Miracle Grow in comparison to a control of an all Responses to all three elements were fairly widespread in the past, and it became customary to apply the three together. 1) The experiment can also include the factor of whether increasing or decreasing the amount of fertilizer has an impact on plant growth in order to derive the perfect amount to be used for plants. Also, large quantities of Ca and Mg are supplied when acidic soil is limed with dolomite. My hypothesis is that more water will result more growth. 1 will grow more than radish with the recommended amount and the control. It was between 9-11 ml. Formulate a Hypothesis: Sarah think plants will grow better if they're in the sun, than in the shade. plants to acid rain and its ultimate effects on plant growth and reproduction are reviewed in next section. Plants need light to grow because it is an important part of photosynthesis, the process plants use to convert carbon dioxide and water into food. The student obtains four identical plants. Measure the roots and the shoots of the growing plants and chart the growth of their seedlings every day or two. Any injury to the root system decreases a plant’s ability to take up water, including root rot, which is caused by too much water. Is the measurement method questionable or unreliable? Due to that, the soapy water plant got plain water. Tap water produced heaver plants, while rain water produced taller plants. Materials Used Statefields School Inc. 3) Water the pots every day. Read also: How to grow hydro: 10 rules of thumb on watering plants Each pot had a total of 6 radish seeds distributed evenly How can we estimate the amount of water that is sufficient for plant growth? Watering a plant with salt water also impedes the amount of water the plant can absorb. How does excess amount of water affect plants? Questions lead to more questions, which lead to additional hypothesis that need to be tested. If you enjoyed this experiment and want to try another variation of it, you could try to grow plants hydroponically-that is, in water instead of dirt-while varying the pH level of the water. Background Research Salinity is when soluble salts are at Procedure Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition. Water evaporates rapidly from the sides of a porous clay pot, which requires more frequent watering than nonporous, glazed or plastic pots. Conclusions…………………………………………………………………………. Measure each plant every day and record your findings in a notebook. Nutrients are drawn from the soil and used by the plant. My prediction from the beginning was basically right I said that saltwater will be slightly bad for the plants and salt water was a poor thing for the plants. 3.The amount … The system we were working with allowed us to test the recommended amount The reason that we place 6 seeds in each paper towel is to see the average result, not the result of an accidentally large seed. plant C? If there is not enough water, the plant cannot get the nutrients it needs to sustain life. Materials: All the materials for this project are available locally. Several new questions may have occurred to you while doing experiments. Question: 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, and contaminants are flushed out of the soil.
