What is your favorite part about Education.com? It's a fantastic kitchen science experiment that works for an ocean unit or a density science lesson. Since this water has been boiled, most of the contaminants will be killed, making the water safer for plants. This is awesome, hence the part about you rocking...and you were actually talking about rocking out with the plants. Virginia Kearney (author) from United States on April 02, 2019: Hi Faizhan--You probably used too high of a salt concentration. As for the plants that do grow in salt water, these plants have developed specialized systems in their roots that filters out the salt and saves the fresh water in water bladders. 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. I assume that this would work but I don't know how sensitive mung beans are to salt concentrations. For gardeners who can access a well, groundwater issues exist too--sometimes negatively affecting plants. But the fourth plant (WGD) will be the control, which means it will only be watered with ¼ cup tap water. Salt in the soil can be drawn into the plant along with water and nutrients. As follows: No safety issues associated with this project. Hi! The experiment found how plants create Abscisic Acid as a stress hormone when the endodermis is exposed to drought or saline environments. 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. This information could help gardeners and farmers to know when saline reaches dangerous levels for radish seeds. Hey keithlinpke--I've seen that one too! Or an experiment where people put some plants in a room with rock music, and other plants with classical. While you may notice the soil around the plant roots stays wet due to the sugar water, the ability to absorb that moisture is blocked. Focus on teaching your preschooler letters to get him started understanding words and eventually reading. Solution J: 8 oz.

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. Mung beans, which are used as "bean sprouts" when they have sprouted would be a good substitute in this experiment. They had predicted that river water would make the plant grow tallest. Thank you so much, keep posting such inspiring experiments.good job. You want them damp and not wet. Outdoor plants in the ground use the soil to filter any excess minerals or contaminants. The concept that’s being tested is to see how much saltwater a plant can withstand. 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. Teaching children about how plants work is often a simple a matter of building on their natural curiosity. The salt in the soil can actually pull water out of the cells and dehydrate the plant. Does the sprout die after germination? Different types of seeds: Radish seeds sprout quickly, but many other types of crop seeds could work as well. What you can put in your conclusion is how you would alter the experiment next time. 7. Zip up the Bags.

Actually, that would make an interesting experiment to see if you can get a plant to mature and grow fruit without soil. There was also Affecting Plant growth by Lemon Lime Adventures. 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. You want to avoid letting them dry out and also avoid having them develop mold. 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. I hope you enjoy doing this and learn something about the environment and how we need to protect it. She also won some special awards because she had tackled a real-world problem. This is the research plan my daughter used for her Junior High Project. thanks. Virginia Kearney (author) from United States on November 10, 2013: Yash, If you are looking for an easy way to do it, you might want to have several bar graphs representing the progression of days with the numbers of germinated seeds indicated by different bars under the different salt concentrations. How you would revise the experiment to make it better. Too much water or just leaving the seeds in water could make them get a fungus. The one on the left was watered with Tea water, the one on the right was watered with tap water.

Answer: This project could be done with all kinds of seeds that sprout easily on wet paper towels or coffee filter paper. Do not let it splash onto the plant’s leaves. Stir to dissolve the salt. They had tested the height of the plant. 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. Saltwater negatively affects plants by dehydrating them. Virginia Kearney (author) from United States on April 21, 2014: Glad you like it Chelsea. On day two, water each plant with 10 mL of water with the designated amount of salt for its row. 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. I wasn't sure how long you would continue this project as well. 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). Most plants can tolerate saltwater on their leaves and stems, but they will dehydrate if they drink saltwater from the soil. 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. 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. When fresh water is present, water is easily passed through the root cells and up through the rest of the plant as needed. It was very cool to watch the colours change! My son had his science fair at region yesterday and won first in his category--he gets to go on to state again now. The radish seeds will not germinate at all in a solution with more than 3 teaspoons of salt in 8 oz. Question: How does salt affect the growth of a radish seed?

Peppers need water like every other plant, but the amount of water and your watering routine has a significant impact on quality. If you do try, you should probably take them home on the weekend so you can have more days of observation. 6. 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. Tell the Whole Story: In her conclusion and results, Maggie wrote the whole story of her experiment, the original failure, and her second try, which is exactly what my husband does when his experiments don't work the first time! Crop yields can be markedly reduced before visual symptoms of salinity damage become apparent. Take ten separate cups. 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 enable strictly necessary cookies to give you the best possible experience on Education.com. Even if they don't dehydrate, they may be poisoned by an excess of salt in their systems. The plants that received distilled water had better growth and more leaves. 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 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. 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. A warm, light area to grow the plants, protected from pests. Your hypothesis is your guess about what your experiment results will be. However, you do need to make sure they have all the nutrients they need. Have one 1/4 cup of water with one teaspoon of salt, one with two teaspoons, and one with three teaspoons of salt. One of the ways they get rid of the salt is to flood the fields with water to let the salt leech out. 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. Also to see what the timeline of the effects are on each plant with the differing amounts of salt being introduced into the water. This osmosis is facilitated by cells around the hairs of the plant's roots that water passes through very easily. My daughter got 1st place in her regional for this project and also went to state. Stir to dissolve. Luckily, the salt tends to prevent the growth of fungus and mold. I'm sure we got them for under a dollar. These are very inexpensive seeds. Saltwater also affects plants by inhibiting their growth and photosynthetic capabilities. Do this simple salt water experiment to teach kids about the respective density of salt water and fresh water. Virginia Kearney (author) from United States on September 04, 2017: Hi Elle! but I've never seen a salt experiment.

Try reducing the salt concentrations by at least half. It may be that is your problem too. I hope this makes sense. This experiment studies how salt affects seed germination. The reason this simple project did so well is that she was able to explain how important it is for farmers to be able to determine when the salt concentration in soil hurts the germination of plants. 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. 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. As saltwater enters the plant cells, all other moisture instantly leaves through the cells permeable membrane. I want to thank you for being so professional in your demonstration. Virginia Kearney (author) from United States on March 01, 2012: Nova--thanks so much for telling me! distilled water with 2 ½ teaspoons of table salt. The cells of the seeds lose water to the saline soluti on via osmosis. This experiment showed that watering plants with any amount of salt water inhibits the growth and life of a plant by dehydrating it. This supported the hypothesis, which was, "The more salt in the water, the fewer seeds will germinate.". You might want to save the solution you make in a sealed container (so it does not evaporate and change the salt concentration) in case you need to do this. I used food coloring and cabbage leaves to show the kids how plants absorb water (and nutrients) up through their stems. Question: How could we find out how much salt mung beans can tolerate? Stir to dissolve. For example, in irrigation water at Carnarvon, only about half the total soluble salt is sodium chloride. Label them A through J. Tap and distilled water without salt were used as controls. Answer: That is a good title for this project. 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. 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.
