一、Soils

There are many different kinds of soils. Different soils have different types of rock and minerals in them. Some soils have more water in them than others. Some soils might have more plant and animal material in them, too.

Different kinds of soils are found in different parts of the world. There are several kinds of soils found in the United States. In some areas, the soil has a lot of clay. Other soils are very sandy. Loam is a kind of soil that has a good mixture of clay and sand.

In some places, soil layers are very thick. Lots of plants grow in places with a thick soil layer. In dry and windy places soil layers are much thinner. Layers of soil on mountains are thin because gravity pulls the soil downhill.

The type of soil in a particular place affects what kinds of plants can grow there. (150 words)

二、Waves

How does light get from the sun to the earth? How does music get from the stage to the audience? They move the same way —in waves!

Light and sound are forms of energy. All waves carry energy, but they may carry it differently. Light and sound travel through different kinds of matter. For example, light waves cannot move through walls, but sound waves can. That is why you can hear people talking in another room even though you cannot see hem. The energy of some waves is destructive. An arthquake produces seismic waves.

Catch a wave. Ask a friend to stand a few feet away from you. Stretch a spring between you. Shake the spring to transfer energy to it. What happens? The spring bounces up and down in waves. When the waves reach your friend, they bounce back to you!

Light waves travel 300,000 kilometers (186, 000 miles) per second! They can also travel through a vacuum. That is why light from the sun and distant stars can travel through space to the earth! (175 words)
