QFD: I am not a vegetarian because I love animals; I am a vegetarian because I hate plants. A. Whitney Brown
?FD: Describe a Cold Front? Warm front?
Objective 5c. Students know the origin and effects of temperature inversions.
1) day 1 0f 2 Weather forecast
WOD: Detrimental – a negative consequence
You will create a 3-5 minute Weather forecast
1) You must write a script for your weather forecast
2) you must edit, and film your video (Optional for EC) Due Jan 15
3) You must create a colored weather map, that includes:
4 cities with high/low temp., 3 forms of precipitation, 2 fronts, a H and a L pressure systems, cloud covers & wind speeds for each city, ec. if you mention a temperature inversion in proper context
5) You may create your map using paint or other program ( optional)
6) You may create your entire presentation using windows movie maker or imovie (optional)
7) You may create a commercial, your commercial should reflect a positive message
I will not provide a camera and time during the last few days in December for your group to film your weather forecast so you need to get together with classmates over the break to finish. You an do this project by yourself
