Have you ever wondered whether a plant or seed needs anything except soil water and light to grow. Here is your chance to learn for yourself.</span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">Go to your local garden store and pick up 5 pots soil and a fast growing seed like radishes. Also get some soil but make sure you purchase regular clay or top soil. You don’t want to get a soil that already has a fertilizer nutrient mixed into the dirt. Get a very small amount of these fertilizers:12-12-12</span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">Nitrogen fertilizer nutrientsPhosphorus fertilizer nutrientsPotassium fertilizer nutrientsYou can also get some plastic bottoms for the pots but you can easily use a plastic container top like a cottage cheese or sour cream top.</span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">When you get home with your supplies you will want to get started right away as the seeds need several days to a week to sproute.</span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">Arrange the pots on a counter area what will be out of your way from everyday work but will allow for them to have adequate light water and be at the same temperature. </span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">In each pot fill it 2/3 full with the dirt. You may want to put a rock in the bottom hole of the pot before you do this. This will keep the soil from running out when you water the seeds but won’t totally clog it up.</span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">Sprinkle several seeds in each pot and then cover them with about another ¼ inch of soil.On one pot sprinkle about 1 or 2 tsp 12-12-12 fertilizer. On another pot sprinkle nitrogen fertilizer nutrients and yet another put phosphorus fertilizer nutrients and on the 4th put potassium fertilizer nutrients. The last pot you will leave with no fertilizer at all.</span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">Use a watering can for this if you can and put about an 1/8 cup of water on each pot. If you bought really big pots you will probably need ¼ cup of water. </span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">Now leave the pots alone and water daily. Watch the pots every day and make a visual observation of any changes you notice. Use graph paper. You may also want to use some chalk and mark a number or letter on each pot to easily graph and plot the information.</span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">Notice the color of the plants as they germinate and also note how fast they eash grow. What did you determine by this experiment. What nutrient caused the seeds to sprout the fastest? Which one grew the fastest and which one grew the tallest.</span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">This is a great 7th or 8th grade science project for kids and also high school students. </span><br /><span style="color:#3333ff;"></span><br /><span style="color:#3333ff;">About the Author<br />Get more information on science projects at http://scienceprojects.fetching.usBindi Watts is a contributor to science projects Source: </span><a href="http://www.articletrader.com/"><span style="color:#3333ff;">ArticleTrader.com</span></a><span style="color:#3333ff;"> </span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/5872296866191085561-8112667338136837686?l=eclipping-science.blogspot.com' alt='' /></div>Alifiahttp://www.blogger.com/profile/00999631714802358741noreply@blogger.com0tag:blogger.com,1999:blog-5872296866191085561.post-85589099900844165302008-04-12T12:21:00.000-07:002008-04-12T12:24:51.153-07:00by <a href="http://www.articletrader.com/author/bindi-17619.html">bindi</a><br /><br />Have you ever noticed that salt is sold in the store when we have snow and ice on the roads? If you have ever wondered about salt and what effect it has on water. If you put salt on the frozen ice in the road it seems to melt so does it keep water from freezing? You have just discovered a science project for the school fair.<br /><br />Science projects are right under our noses and can be as simple to find as looking at what we do every day in our lives.<br /><br />This experiment will not cost you anything except a little bit of ordinary table salt.<br /><br />Get together 3 containers that you can put water into and freeze. They should be plastic that will freeze well. Also you do not want them to be too large. If you can use a sour cream container or a few small plastic cereal bowls that works well.<br /><br />Fill each container half full with water from the faucet.<br /><br />In the first bowl put in 2 teaspoons of salt and stir well to dissolve most of the salt<br /><br />In the second container put in 1 teaspoon of salt and stir to dissolve<br /><br />In the last cup only have water and no salt. Make sure the water is room temperature.<br /><br />Now place them all on a baking sheet and place in the freezer in a stable place that will not tip over.<br /><br />Leave these there all day or over night. In the morning remove the containers and make a visual observation. Were all the containers frozen solid? If not were they somewhat frozen? Did any not freeze at all? Did the amount of salt in the water effect how much the water froze?<br /><br />Make sure to document your information and take photos. This project is not a demonstration that you can do immediately at a fair but you can show what happened to the salt and water combination in the science project.<br /><br /><strong>About the Author</strong><br />Get more information on science project ideas at http://scienceprojects.fetching.usBindi Watts is a contributor to science projects Source: <a href="http://www.articletrader.com/">ArticleTrader.com</a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/5872296866191085561-8558909990084416530?l=eclipping-science.blogspot.com' alt='' /></div>Alifiahttp://www.blogger.com/profile/00999631714802358741noreply@blogger.com0
