I never new that I was going to find it I love it thank you!!! When fresh water is present, water is easily passed through the root cells and up through the rest of the plant as needed. A little extra is all right but you don't want lots of extra water. Virginia Kearney (author) from United States on January 08, 2018: Hi Conny--we bought the seeds at our local seed store. 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. distilled water with 1 teaspoon of table salt. The 50 seeds were then placed on top of the coffee filters, inside the bag. I'm sure we got them for under a dollar. but I've never seen a salt experiment. They had used different types of water and coke for their experiment. Please note: Use the Contact Us link at the bottom of our website for account-specific questions or issues. Your hypothesis is your guess about what your experiment results will be. The concept that’s being tested is to see how much saltwater a plant can withstand. 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. Hey keithlinpke--I've seen that one too! Put 100 seeds on the filter of each Bag. Warning - you are about to disable cookies. Salt water on the leaves and stems will draw water out of the plant. distilled water with 2 teaspoons of table salt. Virginia Kearney (author) from United States on February 06, 2017: Hi Brianna! Most plants are unable to grow out of water that is as salty as the ocean, though there are a few varieties that can. distilled water with 1 ½ teaspoons of table salt. DISCUSSION & CONCLUSIONS: The experiment shows that salt is inhibiti ng the plants’ growth. Take ten separate cups. 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. This is how to do it: put your paper in the bag and add water one teaspoonful at a time. We determined 1 TB worked best for our paper. 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. The takeaway is to avoid watering your plants with saltwater if you want them to thrive. Just wondering if the ziplock bags need to be sealed shut, or should they be open for airflow? I was wondering if seeds need soil to grow or can it grow into a mature plant without soil. Question: What is the link between lack of germination and plant death? A breakthrough scientific experiment conducted by ‘Carnegie Science’ found that soil salinity considerably affects the growth rate in plants. keithlipke from Fort Wayne, Indiana on January 17, 2012: My science project was talking to plants :). Water is one of the three vital components any plant needs to survive. What experiment would you do next to get more information? Question: How does salt affect the growth of a radish seed? Thank You. My question is, do we dampen the filters on a daily basis or skip a day? I would suggest using at least fifty per bag. A good research question is both comparative and quantitative. I wasn't sure how long you would continue this project as well. 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. What is your favorite part about Education.com? The radish seeds will not germinate at all in a solution with more than 3 teaspoons of salt in 8 oz. 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. Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. If you see a lot of water in the bag, it is probably too much water. In your conclusion, you explain: An abstract is a short summary of everything in your experiment. 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. 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. In this experiment you will compare the effect of salt water and fresh water on a plant. Since this water has been boiled, most of the contaminants will be killed, making the water safer for plants. If you see there is some dryness, then add just enough water (of the appropriate salt concentration) to make it moist again. Virginia Kearney (author) from United States on January 24, 2012: Great! Virginia Kearney (author) from United States on March 01, 2012: Nova--thanks so much for telling me! We enable strictly necessary cookies to give you the best possible experience on Education.com. I have till April 11th to complete this so do you think it's possible that I could finish this by April 4th? Also to see what the timeline of the effects are on each plant with the differing amounts of salt being introduced into the water. 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. My daughter got 1st place in her regional for this project and also went to state. Be honest: Scientists are always honest about their results. 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. While that sounds promising, many plants don’t mind tap water. of salt or higher. Some people claim that watering their Maiden Hair fern with green tea works miracles. This is a very interesting project. It's a fantastic kitchen science experiment that works for an ocean unit or a density science lesson. distilled water with 3 ½ teaspoons of table salt. I hope this makes sense. Two weeks is just about right. do you mean fluid ounces? Solution G. 8 oz. All living organisms need salt, and plants absorb theirs through their root system along with their water. Do this simple salt water experiment to teach kids about the respective density of salt water and fresh water. The question is what you are going to test. I am wondering how long time it took in total, from the seeding until finished. Virginia Kearney (author) from United States on January 18, 2012: Thanks for stoping by learnlovelive! 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. distilled water with 3 teaspoons of table salt. 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.
