The document provides information about weather and climate. It defines weather as the current conditions of the atmosphere such as temperature, precipitation and cloud cover, which can change daily due to winds and storms. Climate is defined as the average weather conditions over 30 years for a particular region, and differs from weather which describes shorter term conditions. Key terms are also defined, including atmosphere, temperature, precipitation, air pressure, cloud cover and seasons. Students are asked questions about the current weather and Australia's climate and what they want to learn.

1. Weather!!
Term 2 Science unit of work

2. What is weather?
• The weather is just the state of the
atmosphere at any time, including things such
as temperature, precipitation, air pressure and
cloud cover.
• Daily changes in the weather are due to winds
and storms.
• Seasonal changes are due to the Earth
revolving around the sun.

3. What is climate?
• Climate is the average weather usually taken
over a 30-year time period for a particular
region and time period.
• Climate is not the same as weather, but
rather, it is the average pattern of weather for
a particular region.
• Weather describes the short-term state of the
atmosphere.

4. Buzz words!
• Atmosphere - The atmosphere covers the Earth. It is a thin layer of mixed
gases which make up the air we breathe. This thin layer also helps the
Earth from becoming too hot or too cold.
• Temperature – How hot or cold the atmosphere is at any given point.
Measured in degrees Celsius and Fahrenheit.
• Precipitation – Any form of water falling from the sky, for example
water, snow, sheath and hail.
• Air pressure – The force per unit area exerted on a surface by the weight
of air above that surface in the atmosphere of Earth.
• Cloud cover – The percentage or fraction of the sky that is covered by
clouds
• Seasons - A season is a subdivision of the year, marked by changes in
weather, ecology, and hours of daylight.

5. The weather today
• What is today’s weather like?
• What season are we in?
• What is the temperature today?

6. What do we know about Australia's climate?

7. Is the weather the same in Sydney as
the weather in Alice Springs?

8. What do you want to learn about the
weather?
• Fill out one of the surveys at the front of the
classroom and return it to Mr Williams by the
