This video is supposedly will help those who needs the most in order to do the experiment of various methods of soil erosion. Three ways to do perform the soil erosion are bare soil, soil covered with dry leaves, and grass sod or the soil covered with green grass. This Lab experiment is to determine the more or less soil erosion based on the covered or uncovered soil. I believe its going to an exciting experiment for us all. I hope we all enjoy the experiment.

find Jaguar from the funsciencedemos the big idea today is erosion and how water has the power to shape Our Land but we don't want the water to shape our land too much because we need that so I'll to grow plants we use those plants for food and animals use those plants for food so what you see in front of me are three different types of land this first type is just bare soil it's just so this next has dead leaves on top and the third type has plants growing in the soil this may not look too exciting right now but when it rain that water has the power to change the land and we're going to make it rain to see what that water is going to do to our land  so we cut the stop off of 3 plastic bottles and we put the same soil in each of those three bottles all of these bottles have the same soil we covered this tell with that leaves and we grew some plants in this bottle we've also use other plastic bottles to catch the water that's going to come out of these when we pour it into the bottle we want to pour water into each bottle and see what happens does that water have the power to change the land what do you think's going to happen when we pour water into this bottle and it comes out into the cup will it be any different from the water we pour into this bottle as it comes into the cop be any different when we pour water and it comes out in the  so I'm going slowly pour water in your going to see the water level rise and we'll see what happens with our soil we'll keep it coming and ouch coming out  take a look at the bottle used to catch the water what do you notice what's cloudy so why is it cloudy that's because dirt in the soil from our bottle was washed into the cup the water had the power to actually take the dirt in the soil with it out of the Rolling In The Cut the water moved the soil it shaped the soil  so now I'm going to pour about the same amount of water into the next bottle what do you think's going to happen the water that we catch will it be just as dirty will be less dirty when we even be able to see a difference well that's poor the water find out here we go some pouring water in making it rain adding water  to our bottle  I can see the leaves floating to the top do we have any overflow yes we do stop the rain and see what we have so we zoomed in so you can compare the two this one has a lot of the soil in the in the container this one just has a little bit of the particles a little bit of soil in that water  so why do you think this container is a little bit cleaner or what's different between the two this one had leaves that leaves on top and I think most of these Dead Leaves helped protect the soil underneath from moving with the water so what do you think's going to happen with our third container we have plants growing in the soil what's going to happen when you add water and make it rain in this container here we go let's add the water about the same amount water in what do you think's going to happen here add a little bit more coming out we're going to stop pouring and see if we can compare what we see coming out the water coming out of this container looks a whole lot cleaner than this one in a little bit cleaner than this one the question is why why is this water cleaner I poured about the same amount of water into each container of soil if this one looks really clean what to answer the question why we have to zoom in and take a closer look at what's really going on here  so now we're all set to take the clothes we'll look at why the water coming out of this bottle was so clean and clear compared to the others to do that I'm going to actually lift these plants out of this bottle let's see what happens  what I noticed right away is what comes along with all of the plants will the soil is actually coming out to when I flip it over I think you'll be able to see why  so exhumed we can see what's going on here what is this so staying together why is it staying in place but you can see the roots from our plants through into the soil and almost like little fingers those roots are holding the soil together so when it rains The Roots keep the soil from washing away the roots of the plant that's what keeps the water from a roading the soil besides holding the soil to turn in place routes to another amazing thing to show you that I'm going to squeeze this and I want you to watch what happens where did all that water come from will that came from when we made it rain on our soil the roots of the plants help all that water in  plant roots actually go deep into the soil in this model is going to help us see how deep do they can go we're going to zoom see if we can see those really tiny plant roots that we have growing in our soil we've zoomed in now so you can see these tiny roots in action I'm going to point them out and they actually extend from the plant all the way down to the bottom of our soil I'll point out some of the bigger ones grow down into the soil and think about what they're doing there holding that soil in place all of these tiny roots nutrients from the soil but they're also helping the soil out plants do an amazing job at keeping a rose in from washing away too much so we need that so we depend on that soil to grow plants and animals depend on that soil to grow plants if you want to learn more about plants and soil in a rose check out our links in the video description sometimes it's dirty thanks for watching
