1. Water and Weather Unit Week 15 Directions 1.Prepare your desk for science. 2.Use voice level 0 (no voice) to look at notebook pg. 40 & 41. Think about these questions: What is high pressure? What is low pressure? What is a cold front? What is a warm front?

2. Targets & Warm Up Targets: Students will read weather maps to determine the weather. Warm Up: What is high pressure? What is low pressure? What is a cold front? What is a warm front?

3. Weather Maps Meteorologists make weather maps from information gathered using various weather instruments. There are six basic types of weather maps: –Satellite –Radar –Precipitation –Temperature –Wind speed –Front

4. Satellite Maps

5. Radar Maps

6. Temperature Maps

7. Precipitation Maps

8. Wind Speed Maps

9. Fronts Maps

10. We will focus on… Fronts Maps

11. Table of Contents DateTitlePage Reading Weather Maps46 Once you are finished with the Table of Contents, go to page 46 and add the title and date to the top of the page.

18. Weather Forecast Video Pay attention to the meaning of the four symbols and what weather is expected in areas that have each of the symbols.

19. Practice Reading Maps

20. Questions 1.Which city is likely to have sunny and clear skies with no clouds? 2.Which city is likely to have cloudy skies with no change in temperature? 3.Which city is likely to have warmer temperatures and a few days of light rain? 4.Which city is likely to have colder temperatures and one day with heavy rain thunderstorms? Dallas Austin El Paso Houston

21. Reflection Questions What type of weather can you expect near… – High pressure areas? – Low pressure areas? – Cold fronts? – Warm fronts?

22. Targets (Revisited) Targets: Students will read weather maps to determine the weather.
