how does salt water affect plant growth science project

The Science Behind It: 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. Seed type and water level are two factors affecting the growth of the plants that can be controlled. When the heated water cools, it makes conditions very unstable, so the dissolved salt will leave the water and grab onto the string. These are the steps I took: Purpose- The purpose of my experiment is to see the how the position of a plant affects its growth. Most plants grow best around pH 7.0. Under extreme salinity conditions, plants may be unable to absorb water and will wilt, even when the surrounding soil … This project was performed to determine how different concentrations of salt water effect plants. Salt specifically affects a layer of tissue within the branching root system of plants that causes the release of a stress hormone that inhibits root growth. Question: How do various liquids {tap water, river water, salt water, carbonated water, and soda} effect plant growth? Researcher found that not all types of roots are equally inhibited. For example, we cannot control the amount of light coming through the window. The following plant project ideas provide suggestions for topics that can be explored through experimentation. In this project we learn how plants transport water from their roots to their leaves . Hypothesis: Legoman predicted that the plant that was given the river water would grow the most. No … 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 general understanding of exactly what pH is. Parental Note: This experiment can be completed independently by children 8 years of age and older.The project may require some support to track plant growth and take anecdotal notes over the span of two weeks. Grow your own crystals with salt and water. Links. CALIFORNIA STATE SCIENCE FAIR 2006 PROJECT SUMMARY Ap2/06 Name(s) Project Number Project Title Abstract Summary Statement Help Received Taylor N. Swantek Tea: It Does a Plant Good. The test that will be performed will prove which concentration will have the worst effect. What does Equation 1 mean? First, the plants were purchased and the water was prepared with the salt … To use this service you need to upgrade your membership to active membership level. The pH of your blood is about 7.35. How do light and dark conditions affect the germination and growth of seedlings? I also learned that even though salt water does grow plants it still affects them in many ways. In water cup 1 week 3 we had a mess-up by the experimenters where motor oil was poured into the water cup, how we dealt with the … Protection from Insects 9. Some--like blueberries, azaleas and rhododendrons--like acid soil with a pH from about 5 to 6. Seven, the pH of pure water, is considered "neutral." Always test a small portion of the plant for tolerance … Water Testing by Charla Virkler and Her Willing Helpers/homeschooled Kids. The effect of sodium chloride (NaCl) concentrations (0.0, 60, 120, 240 mM) on growth, osmotic potential, chlorophyll content, protein content of (Vicia faba L.) seedlings was investigated.. NaCl caused an increase in plant height with low and medium concentrations and a decrease with the highest concentration, in both measurement periods. Does Microwave Radiation Affect Seed Growth?Science Projects for BeginnersBotany ProjectsDoes Microwave Radiation Affect Seed Growth?Which Bulbs Are Best for Forcing? The hypothesis is that by measuring the plants growth each day, the largest concentration of salt will harm the plants the most. Growth of both wheat and chickpea was reduced even from low salt concentrations. Home. … This project was performed to determine how different concentrations of salt water effect plants. What are the best conditions for mushroom productions/growth? Use these experiments as described, or expand and modify them based on your own interests and imagination. High salts concentration results in high osmotic potential of the soil solution, so the plant has to use more energy to absorb water. Average data from the class and make appropriate graphs from … https://sciencing.com/happens-put-saltwater-plants-6587256.html Table salt doesn't actually have to come from a salt shaker to affect plant growth. Compare types of artificial light on plant growth. Botany and Plant Growth Science Projects. Do different colored lights affect plant growth? A Science Project for Growing Plants With Coffee Grounds or Soil. Does music affect plant growth? In fact, sodium chloride (NaCl) is very commonly found in soil. I introduced caffeine into the soil of some plants and evaluated the effects of caffeine on the experimental plants in comparison to the control plants that were not exposed to caffeine. Plant growth can be affected by contaminants within the water as well. Frequently, there are no shared species between the beach and the more sheltered or inland areas of the dunes. Salt Pollution: Does salt affect plant growth? Science Fair. Salinity can affect plant growth in several ways, directly and indirectly: Direct soil salinity damages: Decreased water uptake. Scientific Surprise A microwave is a type of energy in the form of electromagnetic radiation. Where the land is used for agricultural purposes, salt tends to accumulate as plants pull other minerals out of the ground, leaving the salt behind. Our results (above) indicate that ph level is a factor in plant height but what exactly is the pollutant does have an effect with motor oil and water having a similar ph but the motor oil plants had slightly less growth overall compared to the water cup. Some plants have even adapted to tolerate chemicals that would usually be toxic, such as various heavy metals. For example, water that contains high concentrations of salt dehydrates plants, prevents them from growing and inhibits their ability to photosynthesize. After coffee is brewed, the used grounds often end in the trash -- but you can add this “waste” to soil to improve plant growth. I've heard of families who tested different kinds of water on plants, in hopes of seeing firsthand what affect (if any) microwaves and filters have on the quality of water. Without light, photosynthesis does not work properly and therefore the plant does not get enough food. 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. Irrigation tends to deliver salt from ground water, where it dissolved out of rocks. 5. This results in less water being available for uptake by the plants, increasing water stress and root dehydration. Can't find your project? There is a $150 … However, not all plants need the same amount of sunlight. “Rain on the plants with a 10% salt solution made using distilled water. Discovering the Best Water for Plants. This is because plants have adapted to their specific environment. 1. Material needed for experiment or a science kit about this title may be available at MiniScience.com. If you have a new project idea that is not listed here, we can assign you a dedicated project advisor to help you on gathering information and designing experiments. For example, plants that grow well in a wet jungle would probably not do so well in a dry desert, lacking enough water. My School. 1st grade . P roblem- Does the position of a plant affect its growth? Abstract. The hypothesis is that by measuring the plants growth each day, the largest concentration of salt will harm the plants the most. Salts in the soil can absorb water. Possible explanations for this are that the effect on growth is due to Cl-toxicity and that this occurs at lower concentrations than the osmotic effect of salinity, or that the metabolic demands of maintaining plant water balance and extracting soil water under saline conditions result in reduced growth. Record observations and measure plant growth parameters on days 0,3,6,9, 12 and 18. Sitemap. How close does a pesticide have to be to protect a plant? What happens to mushrooms grown with no light, or too much light? Use 100ml pf rain on days 3,6, 9 and 12 6. Science Fair . Physical conditions such as temperature and light. Details of this project More details or support for this project is available for the members of ScienceProject.com. What is the percentage of water in various fruits and vegetables? Project description In this project you will design and perform an experiment to test the effect of pH on plant growth. Until now it has not been clear how salt, a scourge to agriculture, halts the growth of the plant-root system. Hypothesis- I think that the … Materials: Greenhouse or sunny window sill, 10 bean seeds, 10 small pots, water… Search this site. Discovering the Best Water for Plants. which were sprayed with seawater showed that lupine seedlings were not tolerant of salt … The ideal situation would be for all 24 plants to receive the same amount of light, so any differences in plant growth will be due to the … Science Fair Project-Plant Growth. Different types of plants require different amounts of water. Materials and Procedure. This is referred to as physiological drought, which, if not corrected, can lead to reduced plant growth. 2011 VIRTUAL SCIENCE FAIR ENTRY. Science project. In my experiment, I followed the scientific method. It means that for each 1-unit increase in pH, the concentration of hydrogen ions (H +) decreases ten-fold. With outdoor plants, you can’t control the plants getting too much water if your area gets a lot of rain, so you need to make sure that the soil has the proper drainage, because too much water will affect plant growth just as much as too little.. Salt water, acid rain and polluted runoff can devastate plant life. When using conserved household waste water, avoid contact with edible portions of the plant. For example, something that has a pH of 6 has ten times as many hydrogen ions as something with a pH of 7, and 100 times as many hydrogen ions as something with a pH of 8, and so on. 7. However, some of the other factors cannot be controlled. CALIFORNIA STATE SCIENCE FAIR 2012 PROJECT SUMMARY Ap2/12 Name(s) Project Number Project Title Abstract Summary Statement Help Received Anna D. de la Rosa Eggcellent Eggshells: How Eggshells Affect Plant Growth J1907 Objectives/Goals The experiment was to measure the effects of eggshell on plant growth. These factors halt plant growth and eventually cause the plant to die. What affect does the brightness of light have on the growth rate of a plant? Type of soil, water, and plants, age of plants, and salt treatment schedule. What we needed: 6 Plants (all the same variety, roughly the same size) Additionally, sodium can cause early onset leaf death, decreasing the photosynthetic ability of the plant. Plant project studies allow us to learn about plant biology and potential usage for plants in other fields such as medicine, agriculture, and biotechnology. Additional Note: This experiment will take roughly two weeks to complete; this calculation takes into consideration both the set up time and time needed for plant growth. To explore the effect of caffein on plant growth, I planted, germinated, and grew mung beans. Salts in the soil affect plants by making water less available, and high salinity is considered a physiological drought. I always wondered if they'd doctored their findings. The test that will be performed will prove which concentration will have the worst effect. Science project. Entry of Water in a Plant Plants need water to grow. Plant Science Fair Project Ideas . Water, along with soil and light, is a necessary component for plant growth. The experiment includes the creation of a supersaturated solution in which the solution (liquid) contains more salt than water can usually hold. In this plant biology science project, you will investigate whether different… Experiments on sea rockets Cakile maritima) and lupines (Lupinus spp.) Soapy water can benefit plants, particularly in controlling certain insects, but it's important to ensure that the soap product you use doesn't have additives that are harmful to plants and that you dilute it sufficiently to avoid damage.
