This PowerPoint and bundle explains the features of our atmosphere. It first describes the composition of our atmosphere of mainly nitrogen and oxygen. It also discusses that there are three variable components to the atmosphere: water vapor, dust particles, and ozone. Ozone is discussed further and there is the distinction between “good” ozone in the stratosphere and “bad” ozone in the troposphere.
Finally, the layers of the atmosphere are discussed and the major components of each. The troposphere is where humans live, where weather occurs, and where most air molecules are located. The stratosphere is where we find the jet stream and where “good” ozone is found. The third layer of the atmosphere is the mesosphere where the coldest temperatures are found and where meteors start to burn due to friction. The top layer is the thermosphere which is the hottest layer and is divided into two sub-layers: ionosphere and exosphere. The ionosphere has many charged particles and is responsible for the auroras and where radio waves from Earth bounce off to return to the Earth. The upper most sub-layer of the thermosphere is the exosphere and it is where satellites and space vehicles orbit.
One of the main assignments with this bundle is Layers of the Atmosphere. This assignments has students distinguish between the four layers and place major components in each.
The main lab with this bundle is UV Radiation and Sunscreens. Students investigate with UV color-changing beads the effects of sunscreen, clothing and sunglasses on UV rays.
Included in the Atmosphere Super Bundle:
• PowerPoint: Atmosphere
• PowerPoint Notes Handout: Atmosphere
• Quiz: Atmosphere
• Quiz Key: Atmosphere
• Worksheet: Auroras
• Layers of the Atmosphere
• Lab: UV Radiation and Sunscreens
This PowerPoint and bundle starts with distinguishing between weather and climate and continues discussing weather conditions and observation. For temperature, it is measured with a thermometer and when combined with humidity can cause heat stress. During air pressure, highs, lows, isobars and barometers are discussed.
Wind speed and wind direction instruments are introduced as are naming winds and the Beaufort Scale for wind speed is explained.
The next topic is water in the atmosphere, so the water cycle, humidity, dew point, clouds and precipitation are explained. Use of a sling psychrometer is explained with relative humidity.
Types of air masses and how air masses interact are discussed with fronts. Cold, warm, stationary and occluded fronts and predicting weather conditions are explained.
Finally, the topic of severe weather, hurricanes and tornadoes are investigated. Hurricanes form in warm, ocean waters while tornadoes form during thunderstorms. More formation information is included as is the Saffir-Simpson Scale (hurricanes) and the EF Scale (tornadoes). And of course, there is the discussion of Tornado Alley.
The lab associated with the bundle is a favorite of students. Students go outside for 4-5 days to collect weather data, including temperature, wind speed and direction, air pressure, cloud type, precipitation, and relative humidity.
