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. 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. How your results compare to your hypothesis. Plants, like people, need a certain amount of salt to survive, but too much can be poisonous. She won first place at our Regional Contest and competed at State. Most plants are unable to grow out of water that is as salty as the ocean, though there are a few varieties that can. Question: What is the link between lack of germination and plant death? 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. You can choose to talk about this in different ways: What do you think about your results? but I've never seen a salt experiment. Talk about the results for each bag and then compare them. Saltwater negatively affects plants by dehydrating them. Each plant will receive 1 more teaspoon than the previous cup, so it would be increasing. 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. Salt water on the leaves and stems will draw water out of the plant. Salt. A good research question is both comparative and quantitative. This is an easy experiment to do that is actually about a very important problem that we need to solve. Too much moisture is going to cause problems with fungus or bacteria growth. As you conduct your experiment, you should record what happens every day on a chart. Interesting! And I'm also planning to do it at my school with a partner. Hey keithlinpke--I've seen that one too! Then three with just regular unsalted water. Each bag will be a little bit different because the number of germinating seeds will change the amount of water needed. What does a plant need to grow? Virginia Kearney (author) from United States on August 28, 2017: Hi, Vaishali, Zip Lock bags are plastic bags that close at the top. 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. 8. Virginia Kearney (author) from United States on January 24, 2012: Great! On day two, water each plant with 10 mL of water with the designated amount of salt for its row. 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. They will read the abstract to get an overview of that experiment and decide if they need to read the full article. We enable strictly necessary cookies to give you the best possible experience on Education.com. Kids will learn to think critically about what environmental factors affect plants, and what plants need to survive. Answer: Do the same experiment but use mung beans. 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. Solution G. 8 oz. Keep your water concentrations in covered containers so that you don't need to make any more of them. Since different papers absorb differently, you will need to adjust the amount to fit your paper. I hope this makes sense. Solution E. 8 oz. What experiment would you do next to get more information? My question is, do we dampen the filters on a daily basis or skip a day? For my introduction, I need to include background research. This is the research plan my daughter used for her Junior High Project. 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 results were that the germination was 100% with the controls, tap and distilled water. When your experiment is finished, you will look at the results and write out what happened. Your experiments will give you the results. The interpretation of the data collected during the experiment is that: The more salt that is exposed to the plants roots, the more the salt dehydrates the plants, therefore causing the plants to die, though most gardeners water their plants with regular tap water, the plant that was the control was watered with no salt water, yet it still wilted. 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. Do you have any suggestions on what I can put so that it is good for people who are reading it who have no understanding of biology at all? Answer: Yes. Make sure the seeds are scattered evenly over the filter. For example if it was a Wednesday and the plant WGA was being watered I would put…, Wednesday, December 22, 2010 height=6 inches. Is it about a two week time frame of observing the seeds? learnlovelive from U.S. on January 16, 2012: science journal and pen (or computer document). keithlipke from Fort Wayne, Indiana on January 17, 2012: My science project was talking to plants :). What is your favorite part about Education.com? 5. This is awesome, hence the part about you rocking...and you were actually talking about rocking out with the plants. Actually, some people grow plants hydroponically, which means in water without soil. Water is one of the three vital components any plant needs to survive. Three plants were watered with saltwater: plants B, C, and D while plant A will be the control. That comparison will be your conclusion. 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. The expectation for this experiment is that the plant with the most amount of salt will wilt first. The variable in this project is the amount of salt in the water. Go back and do salt concentrations that are half your original and that will probably work. Help your child understand more about plant life. This is a very interesting project. Take ten separate cups. You can do this same experiment in many different ways and create an entirely different experiment by changing one or more of the following: Sample question: How do different concentrations of salt in water affect the germination of radish seeds? Tap and distilled water without salt were used as controls. 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. We had fun with this experiment. I was wondering if seeds need soil to grow or can it grow into a mature plant without soil. Keep up the good work, your approach is well-appreciated and you are good at demonstrating thorough processes. She also won some special awards because she had tackled a real-world problem. We did that one time too, and none of them grew. I still think that would make a better experiment, however. 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. 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. Unable to get rid of this excess salt, the plant accumulates deposits in its cells that interfere with a variety of plant processes. And try not to use chlorinated, hard, or city water. THE EXPERIMENT. Question: How do various liquids {tap water, river water, salt water, carbonated water, and soda} effect plant growth? Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. Only add water if they are getting dry. That takes a lot of water and contributes to droughts. This information could help gardeners and farmers to know when saline reaches dangerous levels for radish seeds. This is how to do it: put your paper in the bag and add water one teaspoonful at a time. If you decide to create an account with us in the future, you will need to enable cookies before doing so. And, "You Rock!" Stir to dissolve. For example, cup 4 will have 4 teaspoons of water and cup 3 would have 3. The observable effect that saltwater has on plants depends on just how much salt is in the soil as a result of salt watering. The perfect STEM activity for kids to use a controlled variable and … Most plants can tolerate saltwater on their leaves and stems, but they will dehydrate if they drink saltwater from the soil. It explains your procedures, your results, and your conclusion briefly. That is, the water will move to the soluti on which has a higher concentrati on of salt. One of my younger daughters just did a version of this one for her science fair project in 6th grade. In this experiment, 8 plants will be tested. Of course they can't do that when they don't get enough water. Peppers need water like every other plant, but the amount of water and your watering routine has a significant impact on quality. Outdoor plants in the ground use the soil to filter any excess minerals or contaminants. 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. Question: Why don’t Mung beans grow with salt water? Solution F. 8 oz. was both a pun and a double entendre. Why don’t Mung beans grow with salt water? I never new that I was going to find it I love it thank you!!! Virginia Kearney (author) from United States on May 14, 2017: Hi Vilda, you probably ought to allow at least 2 weeks for this project, although you might get enough results earlier, depending on how fast the seeds germinate. Question: Will mung beans work in this seed germination experiment? Question: How often you water the seeds, if at all? Solution D: 8 oz. If you do try, you should probably take them home on the weekend so you can have more days of observation. The manipulated 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. 3. Label the top and bottom of each bag with the letter of the solution to be used in each one (A through J). One of the ways they get rid of the salt is to flood the fields with water to let the salt leech out. 3. Your hypothesis is your guess about what your experiment results will be. Do not let it splash onto the plant’s leaves. I am wondering how long time it took in total, from the seeding until finished. Pour the solution around the plant. How much saltwater can a plant withstand, and how long until it wilts? Just like us, plants need food, water and air! All living organisms need salt, and plants absorb theirs through their root system along with their water. Farmers sometimes flood their fields to leech out the salt that accumulates in the soil through water evaporation. Another way to do this experiment is to water full-grown plants with different concentrations of saline water. Thank You. Water. The plain tap water is the control. Describe the overall results and then talk about particularly interesting things that happened. The salt in the soil can actually pull water out of the cells and dehydrate the plant. WGA did not grow since Thursday, December 30, 2010. Answer: Check each bag every day to make sure that the paper towel or coffee filter is moist but not wet. Your ideas of why your results came out the way they did. Virginia Kearney (author) from United States on September 04, 2017: Hi Elle! Be honest: Scientists are always honest about their results. The one on the left was watered with Tea water, the one on the right was watered with tap water. The water did not harm the growth and showed no visual effects on the plants. It was very cool to watch the colours change! Plants Need Water. The experiment found how plants create Abscisic Acid as a stress hormone when the endodermis is exposed to drought or saline environments. Virginia Kearney (author) from United States on January 09, 2018: Hi Selena--The amount you put in the bag depends on the paper towel or filter you are using that absorbs the water and keeps the seeds moist but not wet. However, in salinated soil, plants absorb too much salt. Answer: If the seeds don't germinate, then they can't produce a full-grown plant. 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. When the whole paper is wet, you have enough. Mung beans, which are used as "bean sprouts" when they have sprouted would be a good substitute in this experiment. This process results in plants literally dying of thirst. distilled water with 1 teaspoon of table salt. Luckily, she had started her experiment early enough that she had to time revise her procedures, adding less salt in the water, and re-do her experiment. Learn more about two kinds of aquatic biomesÃfreshwater and saltwater biomesÃand how you can tell them apart. 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. Crop yields can be markedly reduced before visual symptoms of salinity damage become apparent. If sodium levels are high enough, then the soil will form hard crusty salt layers on the surface and your plant will defoliate and eventually die. The goal of this middle school science fair project is to examine the effect of caffeine on plant growth. is it wrong? To conduct your own science experiment… distilled water with 3 ½ teaspoons of table salt. The higher the salt level, the more damaging it is to the growth of new plants. Chlorinated water and fees from municipal water sources make a gardener yearn to have a well for irrigation. Here are the types of things that farmers would be concerned about: 4. S is for seahorse in this alphabet worksheet. Try reducing the salt concentrations by at least half. I'm sure we got them for under a dollar. However, these highly-permeable root cells work against the plant when the soil has a high salt content. All plants are watered with ¼ cup tap water every day. It is easy but has a very important point. To do this, coffee filters were wet with 1 tablespoon of salt water from cups that increased in concentration by 1/2 teaspoon of salt in each cup of 8 oz. A breakthrough scientific experiment conducted by ‘Carnegie Science’ found that soil salinity considerably affects the growth rate in plants. The filters were then placed in the plastic bags. However, you do need to make sure they have all the nutrients they need. Kids use their cutting and coloring skills to make grass for the bugs to hide in on this prekindergarten arts and crafts and coloring worksheet. Virginia Kearney (author) from United States on November 20, 2013: Ladruzzi--Check the filters daily. You might want to look up hydroponic plants. And since I'm working with a partner I would need to do 10 trials, and have 4 Independent variables too. The plants type was abbreviated WG, and then the letter of the plant. thanks. My daughter got 1st place in her regional for this project and also went to state. After doing your experiment, you will compare your hypothesis with the data from your experiment. Or an experiment where people put some plants in a room with rock music, and other plants with classical. Stir to dissolve. What Effect Does Saltwater Have on Plants? Virginia Kearney (author) from United States on March 26, 2018: Thanks for the comment Bob. But the fourth plant (WGD) will be the control, which means it will only be watered with ¼ cup tap water. https://www.education.com/science-fair/article/saltwater-effect-grass-plants Instead of coffee filters (which is thin but strong paper that you use to put coffee in and then drip water through it to brew the coffee), you could use any paper towel or napkin.
