That is, the water will move to the soluti on which has a higher concentrati on of salt. 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. 3. In truth, this experiment doesn't really require any particular safety procedures. Chlorinated water and fees from municipal water sources make a gardener yearn to have a well for irrigation. In fact, the overall spiciness is in play based on the amount you water. This process results in plants literally dying of thirst. We also did this experiment with white flowers too! Answer: Do the same experiment but use mung beans. 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. 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! Try reducing the salt concentrations by at least half. Mung beans, which are used as "bean sprouts" when they have sprouted would be a good substitute in this experiment. 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. I never new that I was going to find it I love it thank you!!! This is awesome, hence the part about you rocking...and you were actually talking about rocking out with the plants. Question: How could we find out how much salt mung beans can tolerate? The observable effect that saltwater has on plants depends on just how much salt is in the soil as a result of salt watering. We did that one time too, and none of them grew. If the water was used to boil vegetables, it can act as a natural fertilizer to the soil, but make sure it’s not salted. In this experiment you will compare the effect of salt water and fresh water on a plant. I did 4 trials or 4 levels : .5 tsp, 1 tsp, 1.5 tsp, and 2. I am wondering how long time it took in total, from the seeding until finished. This is the research plan my daughter used for her Junior High Project. 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. Virginia Kearney (author) from United States on August 28, 2017: Hi, Vaishali, Zip Lock bags are plastic bags that close at the top. The containers need to be covered so that they don't evaporate and cause the salt concentrations to increase. Thank You. Does the sprout die after germination? Salts in irrigation water are mainly common salt (sodium chloride), calcium and magnesium bicarbonates, chlorides and sulphates. As you conduct your experiment, you should record what happens every day on a chart. Only add water if they are getting dry. If you need to add water to the bag, you need to use the same solution to ensure that the experiment is the same. The goal of this middle school science fair project is to examine the effect of caffeine on plant growth. Bookmark this to easily find it later. Focus on teaching your preschooler letters to get him started understanding words and eventually reading. This experiment showed that watering plants with any amount of salt water inhibits the growth and life of a plant by dehydrating it. Take ten separate cups. For example if it was a Wednesday and the plant WGA was being watered I would put…, Wednesday, December 22, 2010 height=6 inches. Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. What does a plant need to grow? distilled water with 3 ½ teaspoons of table salt. 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. They had predicted that river water would make the plant grow tallest. I assume that this would work but I don't know how sensitive mung beans are to salt concentrations. What you can put in your conclusion is how you would alter the experiment next time. 7. Stir to dissolve the salt. Crop yields can be markedly reduced before visual symptoms of salinity damage become apparent. Your Hub was about salt, hence the rock pun and you posted a comment about the effects of music on plants. Virginia Kearney (author) from United States on September 04, 2017: Hi Elle! If the seeds are too wet, they can develop mold and that will mean you will have to start the project over again. This information could help gardeners and farmers to know when saline reaches dangerous levels for radish seeds. The variable in this project is the amount of salt in the water. The purpose of this science fair project is to determine how distance impacts the Doppler Effect. In conclusion, simple pure tap water worked best. It's a fantastic kitchen science experiment that works for an ocean unit or a density science lesson. There was also Affecting Plant growth by Lemon Lime Adventures. The plants shall be watered with a solution of ¼ cup water and (depending on the plant I will water them with) different amounts of salt. Answer: I have not done this experiment with mung beans, but I have grown them. Peppers need water like every other plant, but the amount of water and your watering routine has a significant impact on quality. Scientists rely heavily on abstracts when they are researching. 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. Help your child understand more about plant life. If you see there is some dryness, then add just enough water (of the appropriate salt concentration) to make it moist again. Actually, some people grow plants hydroponically, which means in water without soil. Any seeds appropriate to your area would be fine, including ones that are available at Lowes, Home Depot or any garden store. Solution D: 8 oz. The salt in the soil can actually pull water out of the cells and dehydrate the plant. Talk about the results for each bag and then compare them. Label the top and bottom of each bag with the letter of the solution to be used in each one (A through J). 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. Then send your curated collection to your children, or put together your own custom lesson plan. Keep your water concentrations in covered containers so that you don't need to make any more of them. Question: If the seeds need to be watered, do we have to water with their relative solution? Interesting! The amount of salt in soil is a major problem for growers. of water. However, in salinated soil, plants absorb too much salt. 3. You want to avoid letting them dry out and also avoid having them develop mold. If you decide to create an account with us in the future, you will need to enable cookies before doing so. Have one 1/4 cup of water with one teaspoon of salt, one with two teaspoons, and one with three teaspoons of salt. The technique you use for watering your peppers is crucial to the success of your crop whether you are growing bell peppers or Carolina Reapers. Also that the control plant will survive the longest, out of the four plants, according to: To start this experiment you must have at least four plants then label them plant A, plant B, plant C, and plant D. In this case, the plant, wheat grass was used. distilled water with 2 teaspoons of table salt. Question: What is the link between lack of germination and plant death? Answer: The concentration of saltwater is the variable. The experiment could have gone wrong in several ways. The very first time we did this experiment, we found that we had put all of the salt concentrations too high. Actually, that would make an interesting experiment to see if you can get a plant to mature and grow fruit without soil. It is easy but has a very important point. Outdoor plants in the ground use the soil to filter any excess minerals or contaminants. In this experiment, 8 plants will be tested. I will pass this along to my daughter, she will be excited to hear about it. Everything else is constant. Question: Do you need a lot of seeds to see how salt affects seed germination? Thank you so much, keep posting such inspiring experiments.good job. I wasn't sure how long you would continue this project as well. In comparing the results after an average was calculated from each concentration of salt, it was determined that the 8 and 6 ounce salt water concentrations harmed the plant growth the most. 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. The first of sign of sali… Observe the bags daily and record the number of seeds that have germinated in each and any other changes in the seeds. 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. However, if you are required to include this section in your project notes, you can write something like the following: Sample Safety Procedures: You need goggles for the salt water splashing in your eyes, and gloves so you do not transfer bacteria to the seeds. How likely are you to recommend Education.com to your friends and colleagues? That comparison will be your conclusion. 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. Be honest: Scientists are always honest about their results. 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. Question: Will mung beans work in this seed germination experiment? Also to see what the timeline of the effects are on each plant with the differing amounts of salt being introduced into the water. Maggie, who did the experiment first, found that none of her seeds germinated! Question: How does salt affect the growth of a radish seed?
