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.
