  15. Moving Circles Lab V: 2 • Put on your safety goggles. • Fill the plastic container ¾ full of water • Balance the container on the 4 cups and let the water settle.

  16. Moving Circles Lab V: 2 • Slowly squeeze red food coloring onto the bottom of the container toward one side. • Remove ice from cup and place in the container on the opposite side.

  17. Moving Circles Lab V: 2 • Using safety gloves, pick up beaker of hot water and place it under the container beneath the red food coloring. • In your INB, draw a picture and record your observations.

  28. Convection Current Reading V: 0 In your INB, set up a page with the following:

  29. Convection Current Reading V: 0 Read “Why does the wind blow?”

  30. Convection Current Reading V: 0 ANSWER and DRAW A PICTURE IN EACH BOX.

  31. CONVECTION transfer of heat by the movement of warmed matter; hot air/water rises, cool air/water sinks

  32. Hot Air is Less Dense! (so it rises)

  33. What Can Convection Do?

  34. Turn to your partner and answer the question: “What is wind?” “What causes the wind to blow?” • Together, select the explanation you both think is the most accurate. • Share with the class!

  35. CONVECTION Moves air in the atmosphere!

  36. Wind over the shore changes direction because of EARTH’S UNEVEN WARMING & COOLING! CONVECTION

  37. BrainPop What is wind?

  38. What is wind? Wind is air in motion. How is wind made? It is produced by the uneven heating of the earth’s surface by the sun.

  39. What causes the wind to blow? • As the sun warms the Earth's surface, the atmosphere warms too. • Some parts of the Earth receive direct rays from the sun all year and are always warm. • Other places receive indirect rays, so the climate is colder. • Warm air, which weighs less than cold air, rises. • Then cool air moves in and replaces the rising warm air. • This movement of air is what makes the wind blow.

  40. What Causes Wind? Bill Nye’s Explains Wind in 2 minutes! http://www.youtube.com/watch?v=uBqohRu2RRk&feature=related Bill didn’t use the word “convection”… but he described it! How did he demonstrate convection?

  41. BrainPop Video V: 0 Ocean Currents

  42. CONVECTION causes deep ocean currents!

  43. Ocean Currents and Coastal Temperatures

  44. Ocean Currents Map V: 1 Label currents on the ocean map. Cold Currents – BLUE Warm Currents – RED Glue the ocean current map into your INB.

  45. Ocean Currents Map V: 1

  46. Inland vs. Coastal Cities

  47. Wrap Up Questions V: 1 Answer on page of your INB. • Explain how the blue water and red water moved in the container in the Moving Circles lab. • Why do you think they moved that way? • If the water in the containers represented the ocean, how does the water in the ocean move? • Recall that thermal energy moves in a predictable pattern from warmer to cooler areas. How is this concept illustrated in this model?

  48. Grade Level: Text Reading V: 1 • Take out pages 424-433 (wind) OR 437-449 (ocean) • Complete the Reading and Activities for each section • Make a list of the most important points of your reading and activities • Share with someone who did the opposite topic as you

  49. Pre-AP: Stations V: 1 At each station…. • Read the instructions • Complete the task • Discuss the objective of that station

  50. Summary Posters V: 1 Make a poster that includes the following: • A picture of the sun with 8 rays • On each ray, identify how the sun drives convection currents of the wind and ocean. MUST BE IN COMPLETE SENTENCES • Write a summary statement on your poster
