watering plants with salt water experiment

What Effect Does Saltwater Have on Plants? Different types of seeds: Radish seeds sprout quickly, but many other types of crop seeds could work as well. Your Hub was about salt, hence the rock pun and you posted a comment about the effects of music on plants. You do that by putting half the amount of salt in the water, or by putting double the amount of water for each amount of salt. What you can put in your conclusion is how you would alter the experiment next time. distilled water with 1 ½ teaspoons of table salt. Watering plants with hot water "can cause stress to the plant leaf and root systems," Plunkett explains. Virginia Kearney (author) from United States on April 29, 2017: When you say oz. Interesting! Place the 10 Ziplock Bags down on the counter at room temperature. My daughter got 1st place in her regional for this project and also went to state. Plant the seeds: You could do a longer variation of this project by planting some of the seeds that sprout and continuing to water them with the same salt concentration. Keep your water concentrations in covered containers so that you don't need to make any more of them. Answer: I have not done this experiment with mung beans, but I have grown them. Salt water on the leaves and stems will draw water out of the plant. The perfect STEM activity for kids to use a controlled variable and … Too much water or just leaving the seeds in water could make them get a fungus. You might want to look up hydroponic plants. I need to have 2 variables what suggestion could you give? In most areas of Western Australia, about three-quarters of the total soluble salt is sodium chloride, though this may vary in coastal and pastoral areas. The importance of your experiment to real-world problems. Her Science Fair articles are based on her experience helping her children do their projects. Liquids with very high sugar or salt levels can actually pull water away from the plant or seed rather than allowing the water to be absorbed. You want them damp and not wet. We generally kept them sealed shut but if you think you've gotten them too moist, you could leave a corner open to let them evaporate a bit. The plants type was abbreviated WG, and then the letter of the plant. Is it okay to use about four seeds in each Ziploc bag? Stir to dissolve. Crop yields can be markedly reduced before visual symptoms of salinity damage become apparent. For gardeners who can access a well, groundwater issues exist too--sometimes negatively affecting plants. You want to avoid letting them dry out and also avoid having them develop mold. These types of water can leave a residue on plants' leaves, Plunkett says, which can "cause damage or a fungal problem" that could be fatal to houseplants. Stir to dissolve the salt. As the co-ordinator of an elementary science fair, I've seen students do lots of plant watering experiments using different kinds of water, but I've never seen a salt experiment. Chlorinated water and fees from municipal water sources make a gardener yearn to have a well for irrigation. distilled water with ½ teaspoon of table salt. Repeat the watering process every other day until the plants have been watered a total of five times with the salt water, not including day one. Copyright © 2020 Education.com, Inc, a division of IXL Learning • All Rights Reserved. On the groups exposed to salt water, the germination decreased as the salt concentration increased, and no germination occurred at amounts of 1.5 tsp. Here is a cool and easy science project to determine the rate of chlorophyll breaks down and how it affects the color change of grass from green to yellow. of salt or higher. The experiment could have gone wrong in several ways. Though the quality of the water has an effect on the plant’s health, there are many plants that are able to grow even when they are given water that is polluted or that has some salt content. thanks. Why do plants wilt? However, if you have the bag closed tightly, you will probably not need to add more solution. In first trying with concentrated and in second trying with distilled water or normal tap water which we use in our daily life.... Virginia Kearney (author) from United States on August 15, 2017: Hi Farhiya! Solution J: 8 oz. We also did this experiment with white flowers too! Have one 1/4 cup of water with one teaspoon of salt, one with two teaspoons, and one with three teaspoons of salt. Everything else is constant. We had fun with this experiment. Solution I: 8 oz. And I'm also planning to do it at my school with a partner. In your conclusion, you explain: An abstract is a short summary of everything in your experiment. measuring cups....what r these... Actually mam these materials r not available in India so plz mam can suggest some other materials so to perform my IP projects....for my practical exam. You can choose to talk about this in different ways: What do you think about your results? I am wondering how long time it took in total, from the seeding until finished. Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. plants differently? Answer: The concentration of saltwater is the variable. When fresh water is present, water is easily passed through the root cells and up through the rest of the plant as needed. Virginia Kearney (author) from United States on January 18, 2012: Thanks for stoping by learnlovelive! Hypothesis: Legoman predicted that the plant that was given the river water would grow the most. The filters were then placed in the plastic bags. Maggie, who did the experiment first, found that none of her seeds germinated! Trying doing this experiment with mung bean seeds, seeds with salt arnt growing, I closed the bag for first two days and then opened them, control grew but everything else didnt. For some reason, my control fully grew within 4 days except the ones with salt and 1 of them disappeared. You will write what happens each day in a table and then look at those results to write a narrative about your conclusion, which is how your results compared to the hypothesis. All living organisms need salt, and plants absorb theirs through their root system along with their water. Your experiments will give you the results. You can do a variation on this project by watering plants with water with different concentrations of salt to see how salt water affects the growth of plants. Saltwater also affects plants by inhibiting their growth and photosynthetic capabilities. Another child in our family did a variation of this project in 5th grade for her school project, so I know that this experiment also works with younger children, but be sure that your child has at least one to two weeks time for the experimental process. Since this water has been boiled, most of the contaminants will be killed, making the water safer for plants. If you do try, you should probably take them home on the weekend so you can have more days of observation. Plants, like people, need a certain amount of salt to survive, but too much can be poisonous. Plants not seeds: You can do a variation on this project by watering plants with water with different concentrations of salt to see how salt water affects the growth of plants. 4. The one on the left was watered with Tea water, the one on the right was watered with tap water. Focus on teaching your preschooler letters to get him started understanding words and eventually reading. growth by watering the plants with water of varying quality. But the fourth plant (WGD) will be the control, which means it will only be watered with ¼ cup tap water. So please advice if you could. What ends up happening is that water is actually drawn out of the plant, dehydrating it, and causing it to cripple. I did 4 trials or 4 levels : .5 tsp, 1 tsp, 1.5 tsp, and 2. Question: How do various liquids {tap water, river water, salt water, carbonated water, and soda} effect plant growth? do you mean fluid ounces? This information could help gardeners and farmers to know when saline reaches dangerous levels for radish seeds. They found that the hydrogel soil was able to retain water better than sandy soils found in dry areas, and it needed far less water to grow plants. The objective of this science fair project is to examine the effects of acid rain on the growth of marigold plants. Question: How does salt affect the growth of a radish seed? Virginia Kearney (author) from United States on April 17, 2017: Hi Amber--that is a very good question. Place all 10 bags at room temperature out of direct sunlight (seeds don't need light to germinate and light can cause fungus to grow). I would suggest using at least fifty per bag. Question: How could we find out how much salt mung beans can tolerate? Some people claim that watering their Maiden Hair fern with green tea works miracles. Describe what happened day by day to each bag. What does a plant need to grow? A good research question is both comparative and quantitative. The higher the salt level, the more damaging it is to the growth of new plants. For example if it was a Wednesday and the plant WGA was being watered I would put…, Wednesday, December 22, 2010 height=6 inches. learnlovelive from U.S. on January 18, 2012: No problem, Virginia. distilled water with 2 teaspoons of table salt. You could use any container that can be closed so that the water doesn't dry out. my seeds which have salt in it has not germinated at all. Virginia Kearney (author) from United States on March 01, 2012: Nova--thanks so much for telling me! I'm so glad that we have competitions which keep kids interested in science! Question: If the seeds need to be watered, do we have to water with their relative solution? I used food coloring and cabbage leaves to show the kids how plants absorb water (and nutrients) up through their stems. Virginia Kearney (author) from United States on March 28, 2019: I am not sure you can complete the whole project in less than two weeks. The containers need to be covered so that they don't evaporate and cause the salt concentrations to increase. While that sounds promising, many plants don’t mind tap water. The different types of water they used were, tap water, river water, salt water, and carbonated water. I still think that would make a better experiment, however. This is awesome, hence the part about you rocking...and you were actually talking about rocking out with the plants. Solution G. 8 oz. On day two, water each plant with 10 mL of water with the designated amount of salt for its row. distilled water with 3 ½ teaspoons of table salt. I hope this makes sense. Question: What is the link between lack of germination and plant death? Talk about the results for each bag and then compare them. Since you need to check the bags daily to count the seeds that have germinated, it is easy to also check each bag to see if it needs more water. Stir to dissolve the salt. The first of sign of sali… keithlipke from Fort Wayne, Indiana on January 17, 2012: My science project was talking to plants :). How your results compare to your hypothesis. Put a shallow layer of gravel/stones in the bottom of each pot, then top up with soil, until about 3cm from the top of the pot. Sample Abstract of Experiment and Results: The problem was to determine the effect of salt water on germinating radish seeds, and also to determine if there was a maximum concentration that could be tolerated. Someone online did an experiment with two Maidenhair ferns (see below). Too much moisture is going to cause problems with fungus or bacteria growth. Also to see what the timeline of the effects are on each plant with the differing amounts of salt being introduced into the water. I assume that this would work but I don't know how sensitive mung beans are to salt concentrations. Higher salt levels will lead to plant dehydration, and the plant's leaves will show signs of drought and burn (the leaves will begin to yellow, brown and crinkle on the edges) even if it is being amply watered. Please help me out and tell me what I should do I still have a week and 2-3 days left to conduct this experiment. One of the problems with the fields in California is that they have a lot of salt in them. ? Question: Do you need a lot of seeds to see how salt affects seed germination? This is how to do it: put your paper in the bag and add water one teaspoonful at a time. So finding out about how salt inhibits germination and growth is important. 5. Sounds like a great experiment. I want to thank you for being so professional in your demonstration. As saltwater enters the plant cells, all other moisture instantly leaves through the cells permeable membrane. This is a very interesting project. I never new that I was going to find it I love it thank you!!! Label them A through J. And, "You Rock!" In this experiment you will compare the effect of salt water and fresh water on a plant. Salts in irrigation water are mainly common salt (sodium chloride), calcium and magnesium bicarbonates, chlorides and sulphates. Try reducing the salt concentrations by at least half. Your kindergarten and elementary students may have questions about how plants “eat,” “drink,” or grow.Here are a few simple experiments to start with:How leaves get waterWhat leaves need to germinate How water travels through plants How leaves breathe If fresh pine cones are readily available in your area, you might also discu… And since I'm working with a partner I would need to do 10 trials, and have 4 Independent variables too. What is the Doppler Effect, or the Doppler Shift? Sample hypothesis: The more salt added to the water, the fewer seeds will germinate. Divide the 1000 seeds into groups of 100. They had predicted that river water would make the plant grow tallest. If you see there is some dryness, then add just enough water (of the appropriate salt concentration) to make it moist again. but I've never seen a salt experiment. What could we do to improve Education.com? Virginia Kearney (author) from United States on April 09, 2014: Aaliyah--I'm not sure what you mean by dependent and independent variables. In this experiment, 8 plants will be tested. Sugar Water Sugar, like salt, can draw moisture away from plant roots, essentially choking plants to death. distilled water with 3 teaspoons of table salt. For example, in irrigation water at Carnarvon, only about half the total soluble salt is sodium chloride. Virginia Kearney (author) from United States on September 12, 2018: Hi Thomas, I have not tried lettuce seeds but I would assume this project would work with any type of seed that sprouts fairly quickly. https://www.education.com/science-fair/article/saltwater-effect-grass-plants WGA did not grow since Thursday, December 30, 2010. The plants that received distilled water had better growth and more leaves. Do this simple salt water experiment to teach kids about the respective density of salt water and fresh water. Thank You. We did that one time too, and none of them grew. I wasn't sure how long you would continue this project as well. The question is what you are going to test. Saltwater negatively affects plants by dehydrating them. Could watering plants with salty or fresh water remove invasive plants and help restore native plants? I'd love to have you come back and share how it worked for you. Solution C: 8 oz. Three plants were watered with saltwater: plants B, C, and D while plant A will be the control. Just like us, plants need food, water and air! To switch between accounts click on the account below, There are four plants lettered A, B, C, D. The specific plant that was chosen was wheat grass because of its amazing height and its ability to grow faster than most plants. Each bag will be a little bit different because the number of germinating seeds will change the amount of water needed. Question: Why don’t Mung beans grow with salt water? When soil has too much salt, crops won't grow well. Your hypothesis is your guess about what your experiment results will be. For example: Plant B is watered with ¼ teaspoon iodized salt, plant C is watered with ½ teaspoon iodized salt, plant D is watered with 1 teaspoon iodized salt, and plant A is the control and is watered with ¼ cup tap water only and no iodized salt. Water is one of the three vital components any plant needs to survive. DISCUSSION & CONCLUSIONS: The experiment shows that salt is inhibiti ng the plants’ growth. Actually, some people grow plants hydroponically, which means in water without soil. The scientific method is so important, people don't even understand. She also won some special awards because she had tackled a real-world problem. One of the ways they get rid of the salt is to flood the fields with water to let the salt leech out. However, when you use salt water to water a plant, the plant is unable to perform osmosis because the water is too dense. Then send your curated collection to your children, or put together your own custom lesson plan. These are ones used by farmers or home growers. Keep up the good work, your approach is well-appreciated and you are good at demonstrating thorough processes. The Effect of Acid Rain on Marigold Plants, The Impact of Distance on the Doppler Effect, Effect of Artificial Light on Plant Growth, http://www.gardenguides.com/77148-effect-saltwater-plants.html#ixzz19k5aKn5J, Three measuring spoons: with measurements for ¼ teaspoon, ½ teaspoon, and 1 teaspoon. Each plant will receive 1 more teaspoon than the previous cup, so it would be increasing. Learn about the effect of artificial light on plant growth versus natural sunlight and delve into some biology and botany concepts in this science project. Plants Need Water. My son had his science fair at region yesterday and won first in his category--he gets to go on to state again now. Do not let it splash onto the plant’s leaves. 7. We then do the experiment with liquids other than water to see if another type of liquid could be used if … When evaluating the data collected from this experiment it is clear that various water types do play a role in plant growth. distilled water with 2 ½ teaspoons of table salt. Salt. If your experiment doesn't work out but you did everything you said you would do, and you don't have time to revise and do it again, you should still publish your results exactly. I have till April 11th to complete this so do you think it's possible that I could finish this by April 4th? This process results in plants literally dying of thirst. All plants are watered with ¼ cup tap water every day. Solution D: 8 oz. They had tested the height of the plant. Start early: It is always a good idea to start your experiment early so that you have time to re-do it if you have any problems. The plain tap water is the control. A warm, light area to grow the plants, protected from pests. Solution H. 8 oz. Bookmark this to easily find it later. There was also Affecting Plant growth by Lemon Lime Adventures. If you want to test this project with an emphasis on agriculture, you should probably choose a seed crop that is grown by farmers in the ground. Plants obtain water via their root system through osmosis. Your ideas of why your results came out the way they did. WGA watered with ¼ cup water with ¼ teaspoon salt dissolved into the solution. of water. Or an experiment where people put some plants in a room with rock music, and other plants with classical. The 50 seeds were then placed on top of the coffee filters, inside the bag. In this experiment, young ecologists will learn about a type of edge effect: how trees and plants at the edge of a forest can act as a weed filter. Thank you so much, keep posting such inspiring experiments.good job. The radish seeds will not germinate at all in a solution with more than 3 teaspoons of salt in 8 oz. Solution E. 8 oz. If you need to add water to the bag, you need to use the same solution to ensure that the experiment is the same. Pour one tablespoon of solution on the filter in the bag with the same label, making sure it soaks the whole coffee filter. Stir to dissolve the salt. As you conduct your experiment, you should record what happens every day on a chart. The National Student Research Center did an experiment with plants watered with tap, salt, and distilled water. The manipulated It's a fantastic kitchen science experiment that works for an ocean unit or a density science lesson. Now I need to start my Lab report.

Put 100 seeds on the filter of each Bag. Water that has been used for cooking is sometimes strained, cooled to room temperature and used for watering plants. Unable to get rid of this excess salt, the plant accumulates deposits in its cells that interfere with a variety of plant processes. Virginia Kearney (author) from United States on January 21, 2018: Hi Kimi--If none of your seeds with any of the salt concentrations have germinated, you may need to try again using a solution which has less salt. Container and spoon to mix water and salt solutions. Does the sprout die after germination? Question: Will mung beans work in this seed germination experiment? Actually, that would make an interesting experiment to see if you can get a plant to mature and grow fruit without soil. Can you help me make a rough graph of seed germinated vs. salt conc. And try not to use chlorinated, hard, or city water. Answer: Yes. Of course they can't do that when they don't get enough water. Here are the types of things that farmers would be concerned about: 4. What is Saltwater's Effect on Wheat Grass Plants? Observe the bags daily and record the number of seeds that have germinated in each and any other changes in the seeds. When your experiment is finished, you will look at the results and write out what happened. The results were that the germination was 100% with the controls, tap and distilled water. Vaishali--Yes, that was our original plan, but our science fair coordinator did not want us to have two variables. That takes a lot of water and contributes to droughts. Warning - you are about to disable cookies. Learn more about two kinds of aquatic biomesÃfreshwater and saltwater biomesÃand how you can tell them apart. Answer: That is a good title for this project. learnlovelive from U.S. on January 16, 2012: science journal and pen (or computer document). Most plants can tolerate saltwater on their leaves and stems, but they will dehydrate if they drink saltwater from the soil. However, you do need to make sure they have all the nutrients they need. Only add water if they are getting dry. That is, the water will move to the soluti on which has a higher concentrati on of salt. Anything which would hold the water in but not soak the seeds too much. Zip up the Bags. My daughter did the experiment about salt n seeds ,she followed some of your ideas and she won first place in her science fair this yr in 2nd grd. As the coordinator of an elementary science fair, I've seen students do lots of plant watering experiments using different kinds of water, or liquids other than water. In truth, this experiment doesn't really require any particular safety procedures. I hope you enjoy doing this and learn something about the environment and how we need to protect it. They will read the abstract to get an overview of that experiment and decide if they need to read the full article. I will pass this along to my daughter, she will be excited to hear about it.
