Air & Weather Unit Overview


How does the weather change?
Why is it important to learn about the weather?


Students will begin to understand and appreciate that . . .

• The Sun is the most important source of heat. The Sun provides the light and heat necessary to maintain the temperature of the Earth.
• Weather changes from day to day and over the seasons (wet and dry).
• We need to dress appropriately for the weather conditions.
• We need to behave safely in response to storms.
• Weather observations can be organized, compared, and predicted, which can help keep people and animals safe.
• Objects in the sky have patterns of movement. The Moon
moves across the sky on a daily basis much like the Sun.
The movements can be observed and described.
• Understand that scientists use different kinds of
investigations and tools to develop explanations using
evidence and knowledge.


Students will be able to. . .

• Ask and answer questions.
• Plan and conduct simple investigations.
• Employ tools and techniques to gather data.
• Use data to construct reasonable explanations.
• Communicate investigations and explanations.
• Describe the properties of air as it interacts with other materials.
• Describe the properties of air when it is
put under pressure.
• Compare the path a balloon rocket travels
along a flight line to that of an air-filled
plastic bag.
• Compare the action of
moving air and its effects on pinwheels,
bubbles, and kites.
• Describe the direction of the
wind using wind vanes.
• Describe the speed of the
wind using an anemometer.

• Record and organize data from daily weather observations using a class calendar and individual journals.
• Compare cloud types.
• Measure temperature and rainfall.
• Compare seasonal weather
• Identify the changing location of the Sun
during a day.
• Record nightly weather and
the changing appearance of the Moon.


Students will know that . . .

• Air is matter and takes up space. It is all around objects.
• Air interacts with objects.
• Air can be compressed.
• Air resistance affects how things move.
• The pressure from compressed air can
move things.
• Air is a gas.
• Wind is moving air.
• Wind speed and wind direction are
components of weather that can be
described using anemometers and wind
• Wind scales are tools used to describe
the speed of the wind.
• Air has specific properties, which can be measured using tools.
• We use tools to collect data about weather conditions.
• Tools help scientists make better observations.

• Weather can be described by measurable quantities, such as
temperature, wind direction and speed, and precipitation.

• Meteorologists are scientists who study
• There are different kinds of clouds.
• Rain is water that comes from clouds.
• The Sun heats the Earth during the day.

• Each season has a typical weather
pattern that can be observed, compared,
and predicted (in Bangkok - wet and dry seasons).
• Earth materials include air (gases of the atmosphere).

ASSESSMENTAlong with on-going student observations and anecdotal notes, the following assessments can be used to form instruction and provide evidence of student understanding:
