  1. Earth Science Unit Overview: Chapter 4 – Earth’s Water Lesson 1 – Earth: The Blue Planet Lesson 2 – The Water Cycle Lesson 3 – Fresh Water Resources Lesson 4 – California’s Water Supply Chapter 5 – Earth’s Weather Lesson 1 – Earth’s Atmosphere Lesson 2 – Air Current and Wind Lesson 3 – Ocean’s and Air Temperature Lesson 4 – Severe Weather Lesson 5 – Predicting Weather Chapter 6 – The Solar System Lesson 1 – The Sun Lesson 2 – The Structure of the Solar System Lesson 3 – Gravity and Orbit

  2. Air Currents and Wind Lesson Overview: 1) What do we already know? (BrainPop) 2) Vocabulary 3) Drawings 4) Main Ideas 5) Review Earth’s Weather: Lesson 2

  3. Page 1 Air Currents and Wind What do we already know?BrainPOP Teaser What is air pressure? a) The force put on a given area by the weight of the air above it. What variables can change air pressure? a) Temp, volume, altitude, water vapor 3) What happens to air pressure when air is cooled ? a) Air pressure increases because gas particles slow down and get close together. Earth’s Weather: Lesson 2

  4. Page 2 Air Currents and Wind: Vocabulary Part I 1) convection: the transfer of heat through the movement of gas or liquid. 2) Global wind: are winds that blow steadily in predictable directions and over long distances. Earth’s Weather: Lesson 2

  5. Page 3 Air Currents and Wind: Drawings(pg. 244) Earth’s Weather: Lesson 2

  6. Page 4 Air Currents and Wind: Drawings(pg. 245 ) Earth’s Weather: Lesson 2

  7. Page 4 Air Currents and Wind: Drawings(pg. 246 ) Earth’s Weather: Lesson 2

  8. Page 5 Air Currents and Wind: Main Ideas Why are temperatures different around the world? (pg. 244-245) a) Because the earth is curved, the sun energy will be less concentrated in some areas than others. Quick Check (pg. 245) -Critical Thinking: On what part of Earth is sunlight the least concentrated? a) The poles. Earth’s Weather: Lesson 2

  9. Page 6 Air Currents and Wind: Main Ideas 2) How do land and water temperatures affect air pressure? (pg. 246-247)During the day a) the land heats up faster than water, so the air over the water is more dense and wants to go where it is less dense (over the land). Quick Check (pg. 247) -Why does convection happen in liquids and gases but not in solids? a) Convection happens in liquids and solids because the atoms are able to move. Earth’s Weather: Lesson 2

  10. Page 7 Air Currents and Wind: Main Ideas 3) What are global winds? (pg. 248) a) See vocabulary Quick Check (pg. 248) -Critical Thinking: Why did captains need to know where global winds were found? a) To take advantage of the winds and thus, travel faster. Earth’s Weather: Lesson 2
