6th Grade Science – Miss Fox
Scientific Method A series of steps used to investigate a problem
 Be prepared to describe each of the steps in the scientific method
 Purpose
 Hypothesis
 Materials
 Experiment
 Analysis
 Conclusion
Weather: is the condition of Earth's atmosphere at a given time in a given place.
Atmosphere: is the layer of air surrounding Earth.
Troposphere: lies next to Earths surface and is the lowest layer of the atmosphere. The atmospheric pressure is
higher due to gravitational forces. This is the layer were weather occurs.
Meteorology: is the scientific study of weather.
Meteorologist: is a person who studies the cause and effects of Earth's weather.
Weather tools – be prepared to describe how to use each of the following weather tools and what they measure.
 Thermometer – measures temperature
 Compass – is used to determine the direction from which the wind is coming.
 Anemometer – measures wind speed
 Hygrometer – measures humidity
 Barometer – measure air pressure
Properties/characteristics of air
 Air: is a mixture of gases in Earth’s atmosphere. Air is composed mostly of nitrogen (78%) and oxygen
(21%).
 A major source of oxygen in Earths atmosphere comes from plants.
 Three physical states of water in the atmosphere – solid, liquid and gas/water vapor. Be prepared to
give examples.
 The atmosphere/air also contains small particles of dust, volcanic ash, sea salt and dirt.
 Matter: anything that has mass and volume (takes up space) – air which is a mixture of gases is matter.
 Air pressure: the measure of the force with which air molecules push on a surface.
 Air pressure deceases as altitude increases.
 Air temperature changes as altitude increases. The temperature changes result mainly from the way
solar energy is absorbed as it moves through the atmosphere. Some parts of the atmosphere are warmer
because they contain a higher percentage of gases that absorb solar energy.
