Elementary Science Fair Projects - Preventing Soil Erosion Elementary Science Fair Project [sciencetechnology-center.blogspot.com]

In this elementary science fair project we are going to find out what can be done to prevent soil erosion. I think we all know that soil erosion is a very big problem all over the world.

Here are some of the Scary Facts:

Did you know that the worlds' deserts grows by about 16 000square miles a year? In the US alone about 7 billion tones of very valuable topsoil is eroded by streams and rivers, as they carry the topsoil away. Did you know that about 75% of the rocks on earth are made up of small grains and particles that are pressed together under the weight of tons of water over very long periods? These rocks are called "sedimentary rocks." This is a really worrying situation, don't you agree?

Well in this elementary science fair project we are going to be looking at one of the methods we can use to prevent this. We are going to do an elementary science fair project to find out whether planting grass or other plants in areas with a lot of erosion can help.

What you will need for this science experiment:

Some easy growing grass seeds Two rectangular cake pans 2 Tick books of the same size Enough soil to fill the pans A jug to pour the water with Water What you have to doFirst of all you have to fill one of your cake tins with the soil. Plant your grass seeds in this cake tin. Water this tin thoroughly with water. Place this tin in a sunny spot where the grass can grow well. Now you have to gently water your seeds and make sure that the soil in the pan is moist at all times without over watering. Wait for your grass to grow about 3 inches high. Fill up the other cake tin with soil. Water it just enough to be as moist as the tin with your grass in it. Now you have to place the one end of both your tins on your books to make them lie at an angle. Fill your jug with water and pour the water down the cake tin without the grass. Note what happens. Now you pour the water down the cake tin with the grass growing in it. Make a note of what happens. What is the difference? What is the reason for the difference?. write down your explanation.

What happens here is that in the pan without grass the some of the dirt is carried away with the water. This is what happens in nature in places where there is nothing to stem the flow of water. In the pan with the grass growing in it, the grass stems the flow of the water and less soil is carried away with the water. So, by planting indigenous grass and other indigenous plants in areas where soil erosion is a problem, the soil erosion can be slowed down.

Question by : What are best computer science and game design colleges in the world? I want to learn computer science and game design together. What are best computer science and game design colleges in the world, especially in usa and in uk, please? Best answer for What are best computer science and game design colleges in the world?:

Answer by RoaringMice
Most game design employers want you to have either majored in computer science or software engineering, so you're making a good choice. In general, you can get into game design out of any CS program, even if they don't offer many game design classes. You'd gear your CS studies toward game design, and you'd do a game design internship. Game design is a competitive field to enter, and a lot of the work gets done overseas. So be aware of that. It's thus even smarter that you're majoring in CS, because if game design doesn't work out for you, you can work in another CS field, no problem. Some of the best CS programs in the US are at: MIT, Carnegie Mellon, Stanford, UC Berkeley, Cornell, U Illinois Urbana, U Washington, Princeton, U Texas Austin, U Wisconsin Madison, Cal Tech, Georgia Tech, UCSD, U Maryland College Park, Harvard, UCLA. I don't know which of those offer game design. In the UK, my list would include Imperial College London, Cambridge, Oxford, and U Manchester. I would also suggest U Toronto, in Canada.

RIT has one of the better game design programs in the US.
