Quiz 1 Study List 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.
