-Sand (or very dry soil)
-a pan-water


-1st Make a pile of sand in the pan.
-2nd To blow gently on the sand. (People should not stand close to the sand for erosion experiments for kids)


Was ist passiert? Warum denkst du, das passiert ist? 


1st Make a pile of sand inn of the pan. 
2nd Fill the watering can with water.
3rd Sprinkle the top of the pile with water.

Why did this happen?
They happen to be caused erosion. In the first part, you created a “wind”. The ”wind” moves the sand. This happened because the sand was not protected. In the second part, youcreated ”rain”. The ”rain” to move the sand. The sand was not protected.

How could you PROTECT THE SAND?
Would a wall to stop the wind from causing erosion experiments for kids? Try around it, a cardboard wall. Whatwould cause the water to stop erosion? Think about ways to stop erosion. Try it on your pile of sand. Do you think that this will work in the real environment?


Erosion Experiment 2

This experiment we have in our backyard:

Michael mounded dirt in an area of the garden. He insisted on using a piece of dirt on top of his “mountain.” I thought it would fall off … hmm, another erosion experiments for kids!

Once the mountain was made​​, we had to practice patience now, to watch it erode. We also had the neighborhood kids to keep off it!
Every week we would go and measure that mountain. It began as a 42 “wide, 19 1 / 2″ high,including the chunk. We had a chart we have completed. On this we would log the date, height, width, observations and make a little drawing of the mountain on our map in a 1 ”x 2″.

After only two weeks ago, the mound of dirt spread out more than 2 cm and had taken about 3 inches.

After a few weeks (and some rain), showed clear signs of weathering of the mountain:

The song remained at the top! The whole pile of dirt had survived down. (The photo shows a green bean Michael, whom he grew up, rises from the top. In his mind, they climbed themountain and was victorious!)
We would have proposed to continue with the measurements for the 12 weeks of the erosion experiments for kids, but something or someone in the dirt hill during the night and we were not ableto take accurate measurements. But we got to the effects of weather on that dirt mound to see!
By the way, Michael thought it was important to wear the same clothes for each photo. :-)
More about weathering and erosion. We have many of these experiments, too!

Weathering – If stones will be carried by water, wind, or by other means, is that weathering.The floor is made of weathered rock particles, ie without weathering, there would be no bottom. Try to see the following activities, such as rocks can weather.

Chemicals such as weather rock?
Place an equal number of limestone or marble chips in each of the two glasses. Cover the stones in a glass with water and those in the other with vinegar, then screw on the glasses.Let the jars stand overnight. You may find that some bubbles in the glass with the vinegar for the erosion experiments for kids.Ask students about what might speculate mean. The next day, pour the liquid from each tube into separate bowls. Label the cups “water” and “vinegar”. Allow the water to evaporate into the shells. Compare the amount of solid material remaining in the two shells.The shell, which contained vinegar will have a larger amount of solid material. (Limestone, marble and other carbonate rocks react together with acid to carbon dioxide and salts. Rainwater is often acid and lime erode easily. Acidic groundwater dissolves limestone underground, forming caves and sinkholes. Study or visit caves or sinkholes near you. Examine You see other kinds of rocks, whether they react vinegar in the same way as carbonate rocks.

As streams weather rock?
Place a few small, freshly broken pieces of rock or stone in a large plastic container. Softer rocks such as sandstone, shale and limestone work best. Fill the jar about half full with clean water. Set aside a few other pieces of the broken rocks. Close the lid of the glass and shake it 1,000 times, remove the stones and any change in their appearance with the rocks, shaken not been compared. Describe these changes. Filter the water through a piece of filter paper or funnel lined with paper towels. What do you see in the filter paper?You might want to experiment with different types of rocks to see that change more types.What could happen to rock in a stream? (Weathered rock in streams of water and erosion experiments for kids)

How does weather Ice Rocks? (Teacher demonstration)
To completely fill a glass with water and cap it firmly. Place the jar in a resealable plastic bag. Put the jar and the bag in a freezer overnight. If you remove the glass, it will be broken.Handle and dispose of the broken glass carefully. Ask students to predict what could this demonstration, rocks and weather to tell us. (When water freezes, it expands. When there are cracks in the rock solidifies, the expansion may cause the rock to break.)

Erosion – When particles weathered from rocks are carried away, it is called erosion.Erosion is responsible for the erosion of exposed places and depositing sediment in high places.

What happens to a mountain?
Build a “mountain” of the bottom 50 cm high in an undisturbed location in the schoolyard.Note the mountains once a week for three months. Have students measure the height and width and any change in its surface. After observing the mountain for an extended period, ask students to indicate which forces might have caused changes in your mountain. How long do they think the mountain would remain, if you leave it there? (Our experiment above.)

How does vegetation affect soil erosion?
Holes in the bottom of a plastic cup, a sprinkler system. Insert four fifty-seven centimeters of soil in each of the two plant flats. Sprinkle grass seed on the ground in one of them and cover lightly with soil. Two flats with water every day of the shower until the grass is two inches tall. Prop up the ends of the two apartments at a moderate angle bricks or blocks.Sprinkle each evenly flat with water until you see the soil erosion. In which subject the land had eroded more? What could be the effect of removing plants like trees from a steep mountain slope? How could the soil erosion on steep sites be controlled? What other factors may think the students that would affect the amount of erosion? Let the students identify the areas in your community that are steep. Take a trip to search for signs of erosion.

Wave Action – How beaches formed
Slope a generous amount of sand from one end of a dishpan. Add water until the sand is about half covered. Use to stabilize the side of a ruler to create waves even in the shell. Let the students observe the effect of waves on the sand. You should see that the water removed sand from the upper part of the “beach” and places them below the waterline.This is, as sandbars and barrier islands are formed. If you can make very small, fast waves, you can see that the sand is redeposited on the beach.

How does water carry Particles Of Rock And Soil?
Mix some gravel, sand, mud, silt, and clay in a large pot. Add water until the glass. Cover the jar with the lid, shake vigorously then the glass. Let the students observe the glass over a period of time and note how long it will settle for the different materials on the floor increases. They see different layers on the bottom? What is different about them? Allow students to think about different types of streams and rivers. Where would you expect to find a rock or gravel bottom? Where would be a muddy or silty soil? What kind of material could be carried out for the longest distance? (The smaller particles remain in suspension in the water for the longest time. You have a larger ratio of surface to mass and therefore sink experience more resistance from the water, like them.)

Model of the Grand Canyon
Cut the middle section of the short sides of a carton. (The lid of a cardboard box works well.) Cover the bottom of the box with a layer of mud or moist soil. Let it dry on the mud.Cover this layer with another layer of a different color. Repeat with many layers until the box is full, so that each layer to dry. Then you tilt the box under an outdoor faucet with the open end down, and run water in a steady stream on the upper end. Let the students observe how a gorge is formed. Ask students to describe the effect of the various layers to the erosion experiments for kids of the canyon.
