This is a weather game I came across on the NASA Space Place website. It is going to take a little time for you to print and prepare the materials, but I think this would be a hit at any weather themed scout meeting.
Weather Merit Badge
Meteorology is the study of Earth's atmosphere and its weather and the ways in which temperature, wind, and moisture act together in the environment. In addition to learning how everyday weather is predicted, Scouts can learn about extreme weather such as thunderstorms, tornadoes, and hurricanes, and how to stay safe.
Printable helps for requirements:
The water cycle is an important part of any discussion of the weather. This printable water cycle explanation aid will help explain it.
This is a water cycle demonstration which will add some pizazz to a meeting about weather or a Weather merit badge workshop.
Tornadoes are destructive storms are caused by a vortex. You can use the classic “tornado in a bottle” demonstration to explain how a vortex forms. This demonstration goes well with a weather related activity or just for some STEM fun.
Doing the requirements for the Weather merit badge helps Scouts learn about meteorology. They learn about weather hazards, high and low pressure systems, the science of weather, and the water cycle. They explore climates and the way humans alter their environment. They make a weather instrument and find out about careers related to weather.
The Thomas Alva Edison Supernova Award is the silver (second) level Supernova Award for Scouts BSA. To earn this award, Scouts must earn the Dr. Bernard Harris Supernova award, one additional Nova award, and four additional Nova approved STEM related merit badges. They must also complete two additional Supernova activities.
