The water cycle song.

I have chosen this song but there are many interesting ones about the water cycle; search for other ones and learn new things about the water and the Earth.

The Groundwater Story Song.

Severe weather

Severe weather is dangerous. Be sure you don't travel under severe weather risk.

 

• Thunderstorm: an electric storm. The thunder is the sound and the lightening is a bright flash of electricity.

 

 

 

 

 

• Snowstorms: storms with lots of snow.

 

• Flood: It happens after very heavy rain, snow melting or when rivers rise.

 

 

 

• Drought: It occurs when it doesn't rain or rains a little bit for a long time.

The elements of weather

Temperature: we measure temperature with a thermometer.

Wind is air in motion. We measure wind with an anemometer.

 

Humidity is the amount of water in the air. We measure humidity with a hygrometer.

Rain is a type of weather precipitation. We measure the rain with a rain gauge.

 

Changes in matter.

There are two kinds of changes in matter:

- Physical changes.
- Chemical changes.

Physical changes: The matter is the same before and after the change. There is a change in physical properties ( size, smell or colour).

Chemical changes: a material or substance is changed into another one. The change is not reversible, the material or substance is different after this type of change.

Natural materials Vs. man-made materials.

Natural materials

They are found around us.
We have to take them from the living things or extract them from the ground (Minerals).

Man-made materials

We transform natural materials in many different ways, making them man-made materials. This process changes the properties of materials.

Layers of the atmosphere.

-Troposphere: the weather occurs.
-Stratosphere: aeroplanes fly.
-Mesosphere: the coldest layer.
-Thermosphere: astronauts orbit the Earth.
-Exosphere: atoms and molecules escape into space.



 

The air.

The air main components are: nitrogen and oxygen.

NB "other gases" includes carbon dioxide (0.03 %) and small
prportions of other gases icluding argon and water vapour.
