I can explain it to a classmate or teacher orally or written without the use of notes. I can give specific real world examples. I understand the learning goal and can explain the main points. I am still unsure about the fine points, details and/or real world examples. I understand parts of the learning goal. I will need to review the main ideas, details, and examples so that I can become more confident in achieving this goal. I can identify what I have completed and learned, and where I need assistance. I do not understand this learning goal. I do not feel that I would be successful in answering questions about this learning goal. Confidence Level High Medium Low None ***In order to be successful on the quiz for this lesson one should complete the following tasks associated with Chapter 13 Lesson 1. Level Tasks 1 Read Describing Weather page 209 to 214 Respond to the key concept questions and the questions that are associated with them (see below) 2 Create a set of flashcards for the vocabulary on page 214 3 Review the assignments and activities that were associated with this lesson Complete Content Practice A and Crossword Vocab that is attached to this Study Guide Key Concepts these responses should be thorough and inclusive 1. What is weather? the atmospheric conditions, along with short-term changes, of a certain place at a certain time 2. What happens to air pressure as altitude increases? Air pressure decreases. 3. What instrument measures air pressure? a barometer 4. Compare humidity and relative humidity. Both measures the amount of water vapor in the air, but relative humidity compares the amount to the maximum amount the air could contain at that temperature.
5. Compare the shape and altitude of the 3 main cloud types Stratus Cumulus Cirrus Piled, Description Flat, layered heaped, wispy of shape fluffy 2,000- Altitude 0-2,000m Above 6,000m 6,000m 6. Describe fog. What is it, how does it form? Fog is a cloud a suspension of water droplets or ice crystals that forms close to Earth s surface. 7. What is the difference between snow and sleet? Snow consists of ice crystals that fall into cold air without melting. Sleet starts out as snow, melts to raindrops in warm air, and then falls through cold air and refreezes. 8. What variables are used to describe weather? air temperature, air pressure, wind speed and direction, humidity, cloud coverage, and precipitation Use the diagram on page 213. 9. Which process of the water cycle changes liquid water into water vapor? evaporation 10. Which process of the water cycle changes water vapor into liquid water? Condensation 11. How is weather related to the water cycle? Water evaporates into the atmosphere when the air temperature is warm and then it falls back to Earth when the temperature cools enough to cause condensation and precipitation. Additional Vocabulary Be able to explain the difference between the 4 types of precipitation and the weather instruments below. Precipitation Hail ice pellets Instruments Anemometer measures wind Sleet freezing rain Rain water droplets Snow --solid frozen crystals Thermometer measures temperature Barometer -- measures air pressure
Content Practice A LESSON 1 Rain Snow Sleet Hail Directions: Use the diagram to answer each question. Question Rain Snow Sleet Hail What form is the water in when it is in the clouds liquid or solid? What is the air temperature near the clouds warm or cold? What is the air temperature near Earth s surface warm or cold? What is the form of precipitation that falls liquid or solid? How are rain, snow, sleet, and hail part of the water cycle? Liquid Liquid & Solid Liquid Solid Warm Warm Warm Cold Warm Cold Cold Warm Liquid Solid Solid Solid They are different forms of precipitation that move water from the atmosphere to Earth s surface. What role does temperature play in the type of precipitation that develops? Temperature determines whether water falls in liquid or solid form.
