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. If the seeds are too wet, they can develop mold and that will mean you will have to start the project over again. If 100 radish seeds are put in on coffee filters in Ziplock bags and then the filters are saturated with water that has had different amounts of salt added to it, how does the germination rate change and at what amount of salt do the seeds stop germinating? Sample hypothesis: The more salt added to the water, the fewer seeds will germinate. Describe the overall results and then talk about particularly interesting things that happened. 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. Salty water is the test; Fresh water is the control. The containers need to be covered so that they don't evaporate and cause the salt concentrations to increase. Have one 1/4 cup of water with one teaspoon of salt, one with two teaspoons, and one with three teaspoons of salt. Watering plants with hot water "can cause stress to the plant leaf and root systems," Plunkett explains. Your Hub was about salt, hence the rock pun and you posted a comment about the effects of music on plants. How much saltwater can a plant withstand, and how long until it wilts? Virginia Kearney (author) from United States on January 18, 2012: Thanks for stoping by learnlovelive! 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. This experiment studies how salt affects seed germination. 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. 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. Sugar Water Sugar, like salt, can draw moisture away from plant roots, essentially choking plants to death. Does the sprout die after germination? However, in salinated soil, plants absorb too much salt. VirginiaLynne is an educator and mom of 5. 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! 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 plants type was abbreviated WG, and then the letter of the plant. This information could help gardeners and farmers to know when saline reaches dangerous levels for radish seeds. The hypothesis did support the experiment, as predicted, the control plant did live the longest, and the plant with the most salt intake was the first to wilt. As follows: No safety issues associated with this project. This is the research plan my daughter used for her Junior High Project. 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. keithlipke from Fort Wayne, Indiana on January 17, 2012: My science project was talking to plants :). 8. However, when you use salt water to water a plant, the plant is unable to perform osmosis because the water is too dense. Please note: Use the Contact Us link at the bottom of our website for account-specific questions or issues. Your experiments will give you the results. This osmosis is facilitated by cells around the hairs of the plant's roots that water passes through very easily. In fact, the overall spiciness is in play based on the amount you water. 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. What is Saltwater's Effect on Wheat Grass Plants? 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. 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. Peppers need water like every other plant, but the amount of water and your watering routine has a significant impact on quality. Virginia Kearney (author) from United States on March 01, 2012: Nova--thanks so much for telling me! Warning - you are about to disable cookies. When evaluating the data collected from this experiment it is clear that various water types do play a role in plant growth. Different types of seeds: Radish seeds sprout quickly, but many other types of crop seeds could work as well. We also did this experiment with white flowers too! Sodium decreases soil permeability, which reduces the flow of water to the plants possibly affecting germination. Solution F. 8 oz. Observe the bags daily and record the number of seeds that have germinated in each and any other changes in the seeds. What could we do to improve Education.com? Unzip the bags and put a coffee filter in each one. Plants obtain water via their root system through osmosis. It may be that is your problem too. You can choose to talk about this in different ways: What do you think about your results? I'm so glad that we have competitions which keep kids interested in science! Describe what happened day by day to each bag. I just answered a question about whether you could do this with mung bean seeds. 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. The question is what you are going to test. Solution D: 8 oz. The concept that’s being tested is to see how much saltwater a plant can withstand. My question is, do we dampen the filters on a daily basis or skip a day? 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. Make sure the seeds are scattered evenly over the filter. Learn more about two kinds of aquatic biomesÃfreshwater and saltwater biomesÃand how you can tell them apart. Stir to dissolve. But the fourth plant (WGD) will be the control, which means it will only be watered with ¼ cup tap water. If you put about 20 seeds in each bag, would you recommend still adding 1 Tbsp of solution to each bag? How your results compare to your hypothesis. Or an experiment where people put some plants in a room with rock music, and other plants with classical. The very first time we did this experiment, we found that we had put all of the salt concentrations too high. The higher the salt level, the more damaging it is to the growth of new plants. Too much moisture is going to cause problems with fungus or bacteria growth. That is, the water will move to the soluti on which has a higher concentrati on of salt. Focus on teaching your preschooler letters to get him started understanding words and eventually reading. On day two, water each plant with 10 mL of water with the designated amount of salt for its row. In this experiment, 8 plants will be tested. The takeaway is to avoid watering your plants with saltwater if you want them to thrive. Right now in California they have a terrible drought. THE EXPERIMENT. Virginia Kearney (author) from United States on February 06, 2017: Hi Brianna! One of my younger daughters just did a version of this one for her science fair project in 6th grade. Virginia Kearney (author) from United States on March 26, 2018: Thanks for the comment Bob. 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. In truth, this experiment doesn't really require any particular safety procedures. Most plants can tolerate saltwater on their leaves and stems, but they will dehydrate if they drink saltwater from the soil. Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. We enable strictly necessary cookies to give you the best possible experience on Education.com. The experiment found how plants create Abscisic Acid as a stress hormone when the endodermis is exposed to drought or saline environments. Most plants and gardens depend on regular watering to grow, but how often do they really need to be watered? Solution G. 8 oz.
